Introduction
DMS 600 4.2
General about DMS 600 software
MicroSCADA Pro Distribution Management System DMS 600 4.2 (DMS 600) is a new version of Open++ Opera software version 3.3 with extended functionality. DMS 600 functionality is very deeply integrated to MicroSCADA Pro Control System SYS 600 version 9.x (SYS 600). Most of the functionality can be used also with MicroSCADA
SYS 500 version 8.4.2, 8.4.3, 8.4.4 or 8.4.5.
The abbreviation SYS 600 is used only when the topic is valid only for SYS 600. Abbreviation MicroSCADA is used when the topic is valid for both SYS 500 and SYS 600.
DMS 600 is a geographical distribution network management system (DMS). The software extends traditional SCADA capabilities by providing geographically based network views. DMS 600 (Base) package provides network component data management and network modeling to provide network overview and topological coloring to see the network's state. In addition, DMS 600 has many optional modules with advanced functions.
DMS 600 can be used with MicroSCADA, without SCADA or with other SCADA systems using OPC Data Access interface. The software has been designed to assist the operation's personnel of electric companies in monitoring and operating their networks.
Both raster and vector based maps can be used as backgrounds for the network window.
It is also possible to create and use schematic network views, instead of geographically based network presentations and maps.
The software runs on PCs using MS Windows 2000, MS Windows XP or MS Windows
Server™ 2003 operating systems both in separate workstations or workstations connected to a fileserver. Additional (regional) servers can be used to store network data to keep the start up time reasonable in low speed LAN/WAN networks. MS SQL Server, Oracle or MS Access can be used as database for DMS 600. Also other database servers can be used if they support the required features of a DMS 600 database. The graphics-based user interface of DMS 600 is unambiguous and the standard Windows ‘look and feel’, together with the online help, makes it easy to learn.
General about DMS 600 Workstation
The DMS 600 system consists of three programs for users: DMS 600 Network Editor
(DMS 600 NE), DMS 600 Server Application (DMS 600 SA) and DMS 600 Workstation
(DMS 600 WS). The architecture of the DMS 600 system is described in more detail in
System Administration. DMS 600 Workstation (DMS 600 WS) is a program for the operative personnel of electric companies to monitor and operate their medium and low voltage distribution networks.

The functional content of the system depends on the licenses, sublicenses and definition of optional functions (for more information about installing DMS 600, see Installation
Manual and System Administration).
The basis of DMS 600 WS is a distribution network database managed by DMS 600
NE/Integra and real time process data from MicroSCADA. You can control actions using
MicroSCADA graphics, or you can open SYS 600 control dialogs directly from DMS
600 WS. You have control rights to an opened control dialog only if your username and password in the DMS 600 match with the user information in SYS 600 and if you are authorized to control the selected switch.
Open++ Integra is an information management system for a geographical distribution network. It can be used to replace
DMS 600 NE in a DMS 600 distribution management system.

New features and functions in DMS 600 4.2
DMS 600 4.2
Extended automatic fault isolation and restoration
In addition to control actions, the generated sequence file includes the circuit breakers to be checked. The information can be used to check that the circuit breaker feeding the back-up connection remains closed. If that circuit breaker is opened due to relay trip, the restoration will be cancelled.
Switch state updates with modified time and possibility to correct times in event list
The switch control dialog for manual devices includes a control that gives the real time when the switch was operated. In addition, the event time can be changed in the DMS
600 event list afterwards. This enables, for example, the creation of outage reports with corrected event times.
Relational database servers
DMS 600 can use relational database servers (such as MS SQL Server and Oracle) instead of MS Access database to store data. The connection to a database is made using ODBC data source name (DSN) definitions. MS Access databases without DSN definitions are still supported. For Hot Stand By systems, two relational database servers with a replication feature are recommended instead of Access databases.
Parallel network views
It is possible to select the used network view independently in each program instance
(workstation). The user has the possibility to create a new view by moving and hiding nodes and lines in the main view without overwriting already existing data. For example, a parallel schematic diagram can be created (orthogonal schema) to make network operation clear and effective but exact locations of objects can be viewed on a map using a geographic view. All views can use the real time network coloring to show the state of the network as before.
Switch state quality (status) separated from switch state
Separate symbols can be defined for uncertain switch states (open, uncertain or closed, uncertain). These symbols are used when the switch state is known in the SCADA
19
DMS 600 4.2
MicroSCADA Pro
1MRS755274
Operation Manual database but quality is uncertain. In the OPC interface this means that OPC quality
QUALITY_UNCERTAIN used, and in the SCIL API interface the status values 1, 2 or
3 are used. The OPC quality QUALITY_BAD or status 10 (not sampled) cause the state of the switch to be shown as error, as before. The user can define if uncertain state will cause network coloring to use unknown color. Error state will always cause unknown coloring.
Manual state update for switches connected to SCADA
Disconnectors and circuit breakers that normally reserve the state from SCADA can be moved to manual state update in DMS 600. This can be used as a temporary solution, for example, to see known state in DMS 600 if communication to station is broken and
SCADA is not showing the known state. There are separate symbol definitions for closed and open, manually updatable switches.
Distribution Contingency analysis
The user can define sequences that can be used to check if the system is capable of handling known fault situations with present loads. For example, the sequence can check whether there are acceptable back-up feeds when some main transformers have to be switched off. The power of generators and motors can be changed in the study, too.
Power values for motors and generators
Real time measurement values from SCADA can be linked to motors and generators so that the load flow calculation in state monitoring mode can use measured values. In the simulations the user of WS can change the values with simulation dialogs.
IED (relay) modeling
For documentation purposes the network database can include data for any kinds of protection and control devices. For example, distance and differential protection devices with their properties and setting values data can be added. The user can define additional data fields for any protection devices.
LIB 500 not required anymore
DMS 600 can be used with SYS 600 without installing LIB 500. The tools that were earlier available only when also LIB 500 was installed are now available without a LIB
500 installation.

Operation Manual
Improved fault management
• Switching to another fault instance is faster than before since all existing faults are in main memory.
•
Operation is faster when there are several unrepaired faults since switch state changes are not anymore stored to each fault file. For reporting the switch state changes are read from the event log instead of the fault files.
• The fault management dialog is resizable. For example, the list presentation of present faults can be increased so that more information can be seen at the same time.
•
Extreme conditions switch is added. When there are a lot of simultaneous faults and lots of switch state changes, the operation of the system can be changed by pressing one button so that the screen update interval is increased and automatic load flow after changes is switched off.
Customer service points in MV network
A customer service point can be added to the MV network to represent a so called MV customer that has their own transformers. The load or energy data can be given for a service point so that the service point will be included in the load flow calculation without modeling MV/LV transformers owned by the customer.
Generic OPC DA client
The DMS 600 OPC DA client can be used with any compatible OPC DA server to get real time switch states and measurements to DMS. However, alarm indications can be obtained with OPC DA only from MicroSCADA Pro SYS 600 by using SYS 600 specific alarm attributes.
Extended tracing functionality
The user has a possibility to view all switching devices along the selected trace in the tracing order. The list shows the type and the existing state of each switch. Through this dialog a selected switch can be located and it’s switching state can be changed. If the state of any of the switches in the list is changed, the dialog becomes outdated and the trace coloring will be cancelled and the dialog closed. The network window can be zoomed to show all line sections included in the trace to easily see how far the trace continues in the network. This zoom function is available in same shortcut menu where trace functions are located.
Network presentation enhancements
A radial network fed by a circuit breaker but not having any loads connected can be presented with a special no-load color. This helps the user to see which circuit breakers

User and region management
DMS 600 4.2
General about user and region management
Login and logout functions in DMS 600 WS are based on user identifiers (username and password).
Network data can be divided into several regions according to primary transformers and generators. The total amount of primary transformers and generators defines the maximum number of regions.
User right levels can be defined for each region separately. User identifiers, regions and user levels for regions are defined by the administrator. For more information about region and user level management, see System Administration. After a successful login, network windows show the medium voltage network which associates with regions that the user has rights to view. The program operates according to the rights given to the user that is logged in.
Logoff mode
If login is quitted or failed during start up, DMS 600 WS will return to the logoff mode.
DMS 600 WS also returns to the logoff mode after you select File > Logoff. You can login with the menu command File > Login.
DMS 600 software has very strictly restricted functions in the logoff mode. The operation of DMS 600 WS in the logoff mode is restricted to the following:
• Viewing of the medium voltage network switching state
• Viewing of the fault list (fault location is not working)
•
Zooming and panning of the network window
•
Login to the software
• Most menu commands are disabled
• Restricted closing of the DMS 600 WS.
If you close DMS 600 WS in the logoff mode, user logoff is performed in the optionally associated MicroSCADA monitor window. Afterwards the monitor can be used normally but before any control actions can be done you must login to
MicroSCADA again by selecting Main > Login from the
MicroSCADA menu.
User level rights
DMS 600 contains four user levels with different rights:

The user name "Admin" always has all rights for every region and every action regardless of later definitions.
The user needs control rights, for example, to carry out switching operations.
The user level with no viewing rights can be used to prevent the user from viewing the network of a special region.
If a user does not have sufficient rights to perform an action, the action will be disabled in the user interface but the user can still see it.
4.4.
Regions
DMS 600 software uses three different types of regions:
• Dynamic region contains all supplied network components of the primary transformer or generator in the current switching state. The content of a region changes dynamically according to the switching state. Any unsupplied section of the network is not included in the region.
• Normal region contains all network components in the normal switching state (also the unsupplied network components). The content of normal region is saved automatically when the normal switching state is saved in DMS 600 WS (for more
information about saving normal switching state, see 8.4.2, Updating normal switching state).
• Extra regions can be defined to contain freely chosen network components and nodes. This makes it possible, for example, to control the same switching device from the control rooms of several regions.
To carry out a switching operation, the user needs the control rights to only one region type (dynamic, normal or extra region).

Starting DMS 600 WS
DMS 600 4.2
Starting DMS 600 WS
DMS 600 WS is normally started from SYS 600 menu Tools > DMS 600 Workstation
(Open++ Opera > OperaWS in older MicroSCADA versions). SYS 600 login information is used automatically. If the username and password entered in SYS 600 login do not match, the username and the password are required (for more information about user levels, see System Administration). Last successful login username is proposed in the Login window.
DMS 600 WS can also be started by double-clicking the DMS 600 WS icon or the file named OperaWS.exe in file manager. In this case, the integration to MicroSCADA is defective.
DMS 600 WS can be started also from the start menu using the program group added during installation (for more information about the program group, see Installation
Manual. However, to be able to open classic monitor graphics from DMS 600 WS, the program must be started from the classic monitor menu. The way the Monitor Pro graphics are opened is not dependent on how DMS 600 WS is started.
If DMS 600 WS is started but the program is in the logoff state, select File > Login.
During the start up process from MicroSCADA, DMS 600 WS:
1.
Tests the connection to the primary fileserver. If the primary fileserver is disconnected, DMS 600 WS tests the connection to the secondary fileserver. If the secondary fileserver is not responding, an error message is displayed and DMS 600 WS shuts down.
2.
Tests the connection to the MicroSCADA system. If the connection is OK, DMS
600 WS reads the real time status of the switches (from the DMS 600 database) obtained from MicroSCADA via DMS 600 SA or OPC Data Access. If the connection to MicroSCADA is not in use, a message is displayed and the last statuses of the switches are read from the DMS 600 database. While disconnected, changes in the statuses of the switches are saved to the DMS 600 database. After reconnecting to MicroSCADA, the real time statuses of the switches are obtained by DMS 600
SA or OPC Data Access.
3.
Loads the medium voltage distribution network data from the binary network file and the temporary network data from the temporary network file.
4.
Creates a medium voltage distribution network topology from the distribution network data, temporary network data and the statuses of the switches.
5.
Performs the network and protection analysis of the present network topology.
6.

7.
Checks for and announces if any new fault has occurred while disconnected. If new unrepaired faults are found, DMS 600 WS asks if the faults should be displayed on the screen.
Upon completing start up, DMS 600 WS is in State Monitoring Mode. If login is canceled or failed software starts in logoff mode (for more information about logoff mode, see
4.2, Logoff mode). During the Simulation Mode or Switching Planning Mode, the ESC
key returns DMS 600 WS to this mode.

User interface
DMS 600 4.2
General about user interface
In the user interface data is represented in dialog boxes, lists, graphics-based network windows and diagrams, geographic maps, and colors. You can select functions from menus and submenus that are controlled with the mouse and keyboard, or with toolbar buttons. The dialog boxes contain scrolling bars, list boxes, check boxes, option buttons, command buttons, and other elements similar to MS Windows user interfaces.
The user interface of DMS 600 WS consists of title bar, menu, toolbar, status bar, and main and auxiliary network windows showing the distribution network. The toolbar can be hidden with the Window > Toolbar command . If not restricted by the administrator, the Window > Arrange Windows command arranges the windows back to their preset places.
If the pointer is held for a moment over a toolbar button, a description of the function pops up near the button. At the same time, text describing the function is displayed on the status bar.
To display a shortcut menu, right-click the main network window. The menu content depends on the position of the mouse.
To open the Print shortcut menu, right-click any list window. The command opens a separate window for saving or printing the list data. The width of columns can be changed in the preview window. The font used in printing is the defined Base font (for more
information about font definitions, see 7.3.3, User interface fonts settings).
Workstation status bar
The DMS 600 workstation status bar is divided into three separate panes. The first pane is dedicated to application messages and function descriptions. The second pane shows
the active operation mode (for more information, see 8.2, Selecting operational modes).
The third pane shows the main status of application connections. This value is a combination of several options based on the environment configuration. Combinations where the value is 'Online' are presented in the following table. In all other cases, the status text is 'Offline', and the indicator color is red. A yellow indicator color is used when some of the available communication interfaces are not in ‘Online’ state.

maps, see 7.9.2, Outlook of background maps and 7.9.3, Storage location of background maps).
Free database layout can be set network component or object-specifically using the functions in the appropriate data form. For more information about free data form layout,
see 8.7.4, Content of free data forms.
The administrator can specify the symbols, line colors and background color used in the network windows and diagrams. DMS 600 software uses geographic maps as the background for the distribution network. The administrator can set background map usage.
For more information about administrator settings, see System Administration. The size and location of most windows can be changed. The state of the windows (visibility, size and location) is saved when quitting the program.
Network windows
General about network windows
DMS 600 represents the distribution network in two network windows. The auxiliary network window always shows the whole network or selected region(s). The view of a low voltage network with a very accurate zoom is an exception. In that case, the auxiliary network window shows a more general view from the appropriate low voltage network.
The main network window shows a specific area of the network in more detail. The area covered by the main network window is shown as a rectangle in the auxiliary network window. Normally the medium voltage network is visible in network windows. Low voltage networks are always read separately to the memory.

Coloring of network windows
The information displayed in the two network windows can be chosen using the submenus in the View > Coloring menu. The functions focus on the active network window.
The colors represent different kinds of information. The colors of network lines are defined in DMS 600 NE/Integra. It is possible to define fixed and pre-selected pen colors and pen widths for primary transformers and for the MV-feeders. The fixed colors are available parallel to dynamically changing network colors. When presenting feeder topology (View > Coloring > Topology by Feeders), adjacent feeders are colored with a separate color so that an open switch is easy to find. Cold lines, lines in looped connections, earthed and uncertain/unknown lines are presented with separate colors. Main transformer topology (View > Coloring > Topology by Primary Transformers) and conductor types according to predefined classification (View > Coloring > Line Types) are presented. MV voltage levels (View > Coloring > Voltage levels) can be presented with different colors. An extra window with color information is opened onto the screen if needed.
The symbols of MV/LV transformers and substations (diagrams) can be drawn with the defined feeder color regardless of the selected coloring option. The color of symbols, including subsymbols and special symbols, is changed to match the feeder color. You can turn this coloring option on and off by selecting View > Coloring > Use Feeder
Colors For MV/LV Substations.
You can switch between fixed and dynamic coloring modes by clicking View > Coloring
> Use Fixed Colors or by clicking the Fix button in the toolbar.
The function Use Fixed Colors is common for the coloring modes Topology by Primary
Transformers and Topology by Feeders. It is common also for the network windows.
When Use Fixed Colors is selected, a line color legend appears to show the defined colors for the Feeders / Primary Transformers that are visible in the primary network window.
View > Feeder command enables the selection of the feeder by the name or code. The selected feeder is shown in the main network with a warning color, automatically zoomed to the feeder area. Meshed network feeders cannot be zoomed.

General about station diagrams
With station diagrams you can handle station components in greater detail and show the switching states of station components.
DMS 600 WS uses two kinds of station diagram presentations:
•
Station and control pictures from MicroSCADA and
• Internal station diagrams.
A particular symbol in the network window means that the object includes a station diagram presentation. Codes or names of the substations displayed in the network window can be defined in the submenu of the View > Show > Substation Labels menu.
Station and control pictures
Station and control pictures are used for controlling the states of switches.
To open the MicroSCADA station or control picture in a separate window in the State
Monitoring Mode of DMS 600 WS:
1.
Right-click the corresponding symbol or the station diagram in the network window.
2.
Click Diagram in the shortcut menu.
The View > Station Diagram command can also be used to open separate station diagram windows. Type in the name of the station you wish to open in the diagram window. It is possible to have several internal station diagram windows open at the same time.
MicroSCADA control dialogs
When SYS 600 configuration files for switches are available, the SYS 600 switch control dialog can be opened directly by selecting the remotely operated switch in the network window or diagram or in the switch device lists. SYS 600 control dialogs can be used for control actions. In an opened control dialog the user has control rights only if the username and password in DMS 600 match the user information in SYS 600 and if the user is authorized to control the selected switch.
Internal station diagrams
Internal station diagrams are used for managing station component data during simulations. DMS 600 NE/Integra uses only internal station diagrams. Normally internal station diagrams are imported from MicroSCADA. Station diagrams can also be created in DMS
600 NE/Integra (for more information about creation of station diagrams in DMS 600

A value is given as the factor of fuse melting time.
The fuse melting times are based on the melting time diagram. The melting times are average values, because the dispersion of melting times is observed. Fuses are selective if their melting times are different in certain fault current. For the fuses of the same manufacturer, 20% of the longer melting time is considered as an adequate time marginal.
In any other case, the corresponding value should be bigger, about
30%.
Defines the prevention of tripping to be taken into account during the selectivity analysis.
Defines the delayed reclosing time to be used in the selectivity analysis.
The relay of circuit breaker and fuses in relay-fuse protected lines are usually selective if the high-speed initial tripping of the relay clears the transient faults. The fuse, or fuses, operates during a delayed tripping period to isolate persistent faults and to minimize the section of network without supply.

After the receipt of a fault to be repaired, resets states in SYS
600 database for all remote readable fault detectors along the faulted feeder. Also DMS 600 WS could be set to ask confirmation for this for each detector.
DMS 600 SA will check for all faults received from SYS 600 if there already is an unrepaired fault at the same feeder. If such a fault is found a new fault is not generated.
When a fault is removed from the fault management dialog
(repaired, removed or archived), DMS 600 WS will automatically search fault files for the new unrepaired faults.
If a new unrepaired fault is found in any fault file search, DMS
600 WS will ask confirmation to locate it.
Switching data is not stored to fault files of unrepaired faults. If this option is not set, the switchings are read from the switching log file when the fault report is opened for the first time.
This setting will affect dropdown boxes and lists in Fault

Updating network data and normal switching state
Updating network data
When starting up, DMS 600 WS reads network data from the binary network file of the fileserver. Correspondingly, the temporary network data is read.
When an LV network containing temporary network changes is loaded for the first time, the user has to choose whether temporary network changes are loaded or not. The function thereafter depends on the selected option:
Table 8.4.1-1 Options during the first loading of LV network containing temporary network changes
Option: Function:
Yes To All
No To All
Possible temporary network changes are executed for every LV network to be loaded. No further confirmation is asked.
Possible temporary network changes are not executed for none of the LV networks to be loaded. No further confirmation is asked.
DMS 600 NE/Integra can be used to update network data (also temporary network data) while the instances of DMS 600 WS are running. DMS 600 NE/Integra updates the binary network file and the temporary network file in the fileserver according to user input. At the same time, it also sends a message to all instances of DMS 600 WS about the new network data. The binary network file is saved only to the local workstation, if the updating of DMS 600 WS is prohibited.
Update new network data to DMS 600 WS for immediate use by accepting the suggestion in the message window or later by clicking File > Refresh Network Data.

NE is in logon state during a scheduled update, a message is displayed and the user can prevent the update by clicking Stop or pressing ESC within 10 seconds.
Updating normal switching state
When starting up, DMS 600 WS reads the real time status of the medium voltage switches
(from the DMS 600 database) obtained from MicroSCADA via DMS 600 SA. If the connection to MicroSCADA is not in use, a message is displayed and the last statuses of the switches are read from the DMS 600 database. The switching state is used to present the distribution network topology.
During start up, DMS 600 WS reads also the saved normal switching state data from the file. Select View > Show > Abnormal Switching States to view the medium voltage switches, which are in different state, using the defined symbol.
Select File > Save as Normal State to update the existing medium voltage network switching state to the user-defined normal switching state file. At the same time, a message about the new data is sent to all instances of DMS 600 WS. New switching state data is automatically updated immediately.
The user-defined normal LV network switching state file is created in DMS 600
NE/Integra.
The normal switching state also defines the normal region for the region and user man-
agement (for more information about normal regions, see 4.4, Regions).
Locating network components
To locate a network component, select:
• View > Find > Switch/MV/LV Station and select the object from the list. By selecting "Mark", the code and label of the selected object are shown in a white box near the object. By selecting "Locate", the object is located using the default location mark. The list can be sorted according to codes or labels. The sorting order is saved when quitting the program.

General about alarms, warnings, notices and events
Alarms and warnings are generated in DMS 600 WS based on network topology, network and protection analysis and fault location. The presentation of MicroSCADA alarms and warnings is in use if the General Extensions license with the Alarms Presentation sublicense is in use, and the functionality has been selected.
DMS 600 WS alarms and warnings are presented using colors in the network windows and inserting text to notices and an event list. MicroSCADA alarms and warnings are presented with user-defined symbols in network windows and changes in object alarm states presented by inserting text to an event list.
Events are presented using the event list. The contents of the event list is stored to permanent log files. Earlier events can be reloaded in DMS 600 WS. Notices are not stored.
MicroSCADA alarms
This chapter does not apply to the DMS 600 (Base) license.
The General Extensions license with the Alarms Presentation sublicense is required for MicroSCADA alarms.
The alarms of the following object types are transferred from MicroSCADA to DMS
600 WS:
• Disconnector
• Primary substation
•
Circuit breaker
• Measurement
• Fault detector.
The following table shows the MicroSDACA alarm types in the order of criticality

Meaning
The value of the object is currently alarming and the alarm information has been acknowledged.
The value of the object is currently warning. This alarm type in DMS 600 WS contains both the low and high warnings of MicroSCADA.
The value of the object is not warning or alarming.
It is possible to define symbols for the first four alarm/warning types in the table. For more information about symbol definition, see System Administration.
If the primary substation is drawn using a substation symbol, the alarm symbol common for all substation components is used. If the substation has several objects having alarms or warnings, the alarm symbol for the whole substation is the most critical and it uses the criticality order.
Unacknowledged alarming primary substations, circuit breakers, disconnectors, fault detectors and measurements can blink in defined colors. The symbol is the same that is used for an unalarming object, for example, the symbol used for an open circuit breaker in the current zoom level. The symbol is blinking switching between the defined blinking alarm color and the normal symbol color. The interval for the color switching is 1 second.
Blinking can also be disabled from all workstations, for more information about setting, see System Administration.
MicroSCADA alarms are also visible in DMS 600's events list, which means that they are stored into a permanent log.
Showing alarms and warnings in network windows
In the network topology presentation the unsupplied lines, lines in looped connections, and earthed or uncertain lines are presented with separate colors. For more information about the settings for topology alarming, see System Administration.
Warning level and alarm level colors are used to present the network and protection analysis results when the calculated values exceed the corresponding settings for the limits. The way the calculation results are presented depends on the network coloring

Simulation of historical events
General about historical events
Any switch state change event can be found from the saved event history log files. With the step-by-step proceeding list of state change events you can analyze the situation before and after a historical event. A topology analysis and load flow and fault current calculations are performed, and the results are shown on the screen after each step. Load models for the selected time are used in a network analysis if the load curves are in use.
The simulation can be used for training purposes with real situations.
Step-by-step simulation contains the switch state changes of:
• Disconnectors
• Circuit breakers
•
MV fuses
• Line sections.
The possible events for the devices are Open, Close and Uncertain. Other devices are skipped in simulation and LV switching actions are not included.
Alarm states of the devices are updated during the step-by-step simulation according to the alarm information and saved into the event list.
Significant uncertainty occurs when using event log files created with Open++ Opera version 3.3, because the normal switching state file must be used as a starting point in the historical simulation of those weeks (the normal switching state of medium voltage network is saved to the file by selecting File > Save as normal switching state). Some extra uncertainty occurs because the normal switching state file

texts (for more information, see 7.8.5, Setting up switching state document).
A switching state document can also be generated automatically (for more information about automatic generation of document, see System Administration).
The document is created using MS Word. The program has to be installed in the workstation. The supported MS Word versions are 97, 2000 and 2002.
Inserting the value for additional load and border switch
This chapter does not apply to the DMS 600 (Base) license.
The Extended Data Management license is required for the definition of additional load and border switch. The additional load points and border switches have to be defined as separate load points in DMS 600 NE/Integra before they can be used in DMS 600 WS.
Separate load points connected to any node in the medium voltage network can be used in network calculations. The separate load points are taken into account during the network calculation by adding the active power of the measurement to the active power of the node.
Separate load points connected to a disconnector, which is the ending point of a branch can be used to model additional loads or a supply from a neighboring network that is not included in the network database. If the state of the disconnector is 'closed' and the value of the measurement is negative (<0), the switch node supplies electricity to the network. The branch becomes energized or a loop connection is formed if the electricity supply to the switch is also coming from another direction. The discovery of loop connection is presented with a different color in the network window. If the supply is coming only from the switch, the network supplied by this switch is colored with its own color in the network window.

Topology management
Basic functions in topology management
1MRS755274
General about topology management
Topology management in the DMS 600 WS network is an advanced and computerized method which replaces the pins on a wall and/or mimics.
The state of switches defines the topology of the network. Topology management in
DMS 600 WS is based on the integration of DMS 600 and MicroSCADA (for more information about integration, see System Administration and Integration with SYS
600). DMS 600 WS contains information on the switching state of the distribution network, that is, information on the states of all remotely and manually operated switches
(including fuses) and line sections. In addition, you can use the manually updateable measurement data of border switches in topology management (for more information
about border switches, see 8.19.2, Inserting the value for additional load and border switch).
The states of switches that are connected to MicroSCADA are updated using the
MicroSCADA station and control pictures or control dialogs. If there is no connection between DMS 600 and MicroSCADA, DMS 600 WS opens a dialog box in which you can update the state of the switch. The status of line sections is always updated in DMS
600 WS.
Switch state quality (status) received from SCADA
The DMS 600 interface to SCADA systems includes separate management of switch state and its quality data. Separate symbols can be defined for uncertain switch states
(open, uncertain or closed, uncertain). These symbols are used when a switch state is known in SCADA database but switch quality is uncertain.
In an OPC interface, OPC quality QUALITY_UNCERTAIN and in a SCIL API interface, status values 1, 2 or 3 are interpreted as uncertain.
OPC quality QUALITY_BAD or SCIL API status 10 (not sampled) will cause the state of a switch be shown as error.
The user can define whether uncertain state will cause the network coloring to use unknown color. Error state will always cause unknown coloring for the network.

Operation Manual
Monitoring network topology
Normally the medium voltage network is visible in network windows. Low voltage networks are always read separately to the memory. All functions focus on the active network.
Every change in the state of the switches causes an update in the network topology (unless the topology is disabled in the general settings, for more information about general set-
tings, see 7.4.1, Defining automatic function settings). The new network topology is
immediately shown in the user interface.
After a failure in the MicroSCADA system or in data transfer between DMS 600 WS and MicroSCADA, the real time switch status is read from MicroSCADA and the network topology is updated accordingly.
The switch and measurement objects can have both an OPC code and a scadacode defined.
If the OPC interface is closed in DMS 600 SA, the switch states and measurement values having scadacode definition are still transferred through the SCIL API interface.
If the OPC interface is closed in DMS 600 WS, the switch states and measurement values that are transferred through the SCIL API interface of DMS 600 SA are also transferred to DMS 600 WS.
Select View > Coloring > Topology by Feeders to display the adjacent feeders of the real time topology with different colors. The feeder topology color settings are used in network diagrams, internal station diagrams, and in the root points of MicroSCADA station and control pictures.
Select View > Coloring > Topology by Primary Transformers to display all lines fed from the same transformer in the real time topology with a common color.
Select Window > Notices and Events to open a window containing the last alarms of
DMS 600 WS.
Network topology coloring has special colors for the following (these also generate a warning to the list):
• Looped connections (alarm also)
•
Unsupplied lines (alarm also)
•
Uncertain state
• Grounded lines (temporary grounding or grounding switch).
The state of a switch is shown with the defined symbols of the network.
The definition of symbols and line colors is made by DMS 600 NE/Integra (for more information about definitions, see System Administration).

Changing switching states
General about switching states
• The switching states of all switches connected to MicroSCADA (real process objects and virtual process objects) are updated using the MicroSCADA station and control pictures or control dialogs.
• If there is no connection between DMS 600 and MicroSCADA for a switch, DMS
600 WS opens a dialog box in which you can update the state of the switch.
• The state of line sections is always updated in DMS 600 WS.
DMS 600 WS has to be in State Monitoring Mode when updating the real time state of the switches. In Simulation Mode the changes are saved temporarily for the use of the workstation.
In Automatic Fault Isolation and Restoration Mode, DMS
600 WS performs the switching actions automatically.
9.2.2.
Changing switching state of switches connected to MicroSCADA
Switches that are connected to the MicroSCADA process can be either remotely operated real process objects or manually operated virtual process objects. For more information about the integration of switches, see System Administration and Integration with SYS
600.
The switching states of switches are updated with the dialog boxes of DMS 600 WS only if there is a failure in the MicroSCADA system or in the data transfer between DMS
switch to Simulation Mode. When data transfer capabilities are recovered, the real time switch status is read from MicroSCADA and the network topology is updated accordingly.

information about general settings, see 7.4.1, Defining automatic function settings).
Manual state update for switches connected to MicroSCADA
Disconnectors and circuit breakers normally receive status information from SCADA, but they can be changed into manual mode in DMS 600. In the manual mode, the state can be updated like any switches that are not connected to SCADA.
Manual state can be used, for example, as a temporary solution to update and monitor the state if communication to the station is down. Closed and temporarily open manually updatable switches have different symbols.
To change a switch into manual mode right click the switch and select Manual state
update. This option is available only for switches that are connected to MicroSCADA and that are not in manual mode. The switch changes into manual mode, and a dialog opens, where you can update the state of the switch. If the quality of the switch was uncertain or bad, it will be restored to normal.
To restore the switch back into normal update mode, unselect Manual state update.

Network and protection analysis

General about network and protection analysis
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license is required for network and protection analysis.
DMS 600 WS network analysis replaces traditional off-line calculations with on-line calculations using the real-time state of the network.
With the network and protection analysis you can examine the electrical state of the network and assure the technical functionality of the network in various circumstances.
Network and protection analysis functions require the Network Analysis license.
Network analysis functions offer calculations for load flow and fault current (2- and 3phase short-circuits and earth-faults) and the protection analysis of radial-operated and meshed networks.
Generators and synchronous motors are taken into account as a source of short-circuit current. The strong starting currents of asynchronous induction motors can be studied in the load flow calculation. Additionally, distributed generators and capacitors are taken into account in the load flow calculations. The calculations can also use measurement data provided by MicroSCADA.
With the protection analysis function you can analyze overcurrent relays that have definite time-delays and inverse time types. The data source of all relay settings can be changed between network models and active relay settings via MicroSCADA. In addition, the medium voltage fuses are taken into account during the protection analysis. The solid earthed networks and networks earthed via resistors are supported in the protection analysis.
The network analysis has different kind of aims in network information system and distribution management system. The network analysis of the network information system is made in the peak load condition to be able to focus on the improvements and additions of the network. With the network analysis of DMS 600 you can analyze the real-time network state and, thus, ensure the most effective and safe use of the network. The load flow in DMS 600 is calculated using the given or estimated load information.

Load modeling
1MRS755274
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license (with the Extended Load
Modeling sublicense) is required for network analysis.
Load modeling uses Velander's factors or defined load models (load curves) to change annual energy information for active and reactive power. The load model is selected normally during the installation. The load model selection can be changed later on. In this case, the programs must be restarted and the network database updated.
The loads of MV/LV stations and customer nodes (if LV networks are included) and the effect of capacitors are taken into account in load modeling during the network analysis.
The loads inside the primary substations are not modeled. The load modeling uses singleline modeling that is capable to analyze balanced medium voltage networks (all medium voltage lines are 3-phased and the load on medium voltage side is nearly equally distributed to all the three phases).
Manually updateable, separate load points connected to any node of the medium voltage network can be used to model the separate load point, load of the border switch or backup feeder from neighboring distribution network. The separate load points are taken into account during the network calculation by adding the active power of the load point to the active power of the node.
Manually updateable, separate load points connected to a disconnector that is the ending point of a branch, can be used to model an additional load or supply from a neighboring network that is not included in the network database. If the state of this switch is 'open', the switch is handled normally in calculations. If the state is 'closed' and the value of the measurement is negative (<0), the switch node supplies the electricity to the network.
The branch either becomes energized or a loop connection is formed, if the electricity supply to the switch is also coming from another direction. The discovery of the loop connection is presented with a color code in the network window. If the supply is coming only from the switch, the network supplied with this switch is colored with its own color in the network window. This network is not calculated during the load flow calculation.
If the positive active power measurement is inserted into the switch, the amount of active power is added to the power of the node as in the case of separate load points.

Load forecasting and load estimation
DMS 600 4.2
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license (with the Extended Load
Modeling sublicense) is required for network analysis.
Load forecasting means the calculation of load forecast for MV/LV stations and line sections for the next 0...168 hours. The forecast is based on the load data of MV/LV stations or LV/MV network customers depending on the selected load modeling method.
Load estimation means the correction of loads given to MV/LV stations so that the total calculated loads of the feeders approximate to the current measurement of the feeder.
The electrical state of the network can then be calculated as accurately as possible. The absence of load estimation means that the forecasted loads are created directly from the given MV/LV station load data.
DMS 600 SA automatically calculates a load estimation and a load forecast for the
MV/LV stations once an hour. The calculations use the latest MicroSCADA measurement
data (for more information about MicroSCADA measurements, see 10.2.4, Using of
MicroSCADA measurement data in network analysis ). After the load forecast database
is updated, it is loaded to be used in DMS 600 WS workstations.
Showing load curve for MV/LV stations and line sections
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license (with the Extended Load

DMS 600 SA maintains load forecasts for MV/LV stations as a background process.
Load estimation is used to correct the given loads of MV/LV stations so that the total calculated load of the feeders approximates to the current measurement of the feeder
once in an hour.
To show the load forecast graphically:
• Open the shortcut menu by right-clicking a node or a line section. Select Load

• The red line describes the forecasted load generated in the load estimation.
The window also contains the forecasted maximum and minimum powers and the interval of them from the present time. In case of a line section, the forecast calculation is started to illustrate the forecast in the window.
With the load curve information for a selected line section you can find a convenient time period, for example, for a maintenance outage. To show the distance from the present time and the forecasted load in that time, click the load curve.
Using of MicroSCADA measurement data in network analysis
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license is required for network analysis.
The configuration of the connection between MicroSCADA measurements and the DMS
600 network database is made in DMS 600 NE/Integra (for more information about configurations, see System Administration).
If the measurement data is connected to the nodes of the network, the measurement data serves as input data for the network analysis of DMS 600 WS in the following way:
• To make the load data of the feeder and the MV/LV stations more accurate, use the current measurement connected to the feeder's node or to the node that limits the
MV/LV station and the feeder (node type feeder) during the load estimation (for
belongs to a feeding HV/MV substation cannot be used in the load estimation.
• A current measurement, an active power (P) measurement, or a reactive power (Q) measurement connected to a motor node: The change in motor measurement data affects to the load flow calculation results in the radial calculation of WS. If only current measurement is available it is used so that the voltage in the measurement point is used to estimate the total power (S). In Simulation Mode the user can switch the P and Q values. When returning to State Monitoring Mode the real measurement values are restored.
•

•
Use the primary substation voltage measurement as a supplying voltage for feeders in the load flow calculations. When available, always use the measured voltage instead of the primary transformer's nominal voltage from default busbar voltage
node belonging to the HV/MV substation which is used in the calculation. A voltage measurement connected to a feeder node cannot be used in the calculation.
• Separate load points connected to any node of the medium voltage network can be used in network calculations. The separate load points are taken into account during network calculation by adding the active power of the measurement to the active power of the node.
• Separate load points connected to a disconnector that is the ending point of a branch can be used to model additional loads or a supply from a neighboring network that is not included in the network database.

Using starting motors in network analysis
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license is required for a network analysis.
The use of starting motor data means that the real and reactive powers of induction motors are replaced with the starting current and power factor during a network analysis.
You can define only induction motors to be used as a starting state in the network analysis.
To define induction motors that are in the starting state:
1.

When the start up process is completed, DMS 600 WS is in State Monitoring Mode (if the fault location is not started). A medium voltage network topology is displayed in the main network window.
The network analysis is automatically performed during the start up process. The network and the results of the network analysis in the network windows are based on data from the network database, temporary network and real time switching state. The feeding voltage (busbar voltage) is received from a primary substation voltage measurement or from primary transformer settings and the loads are received from the given load information and from separate load points. The current measurement is used during the load estimation to make the load data of the feeder and MV/LV stations more accurate.
An auxiliary window contains the voltage drops in different parts of this existing medium voltage network. The default contents of the windows can be changed during projecting.
The change in network and/or switching state data automatically recalculates the network and updates network topology on screen (if not disabled in the general settings. For more
information about general settings, see 7.4.1, Defining automatic function settings). The
analysis is executed for radial feeders. After this the meshed network load flow and maximum short-circuit current calculation for the whole medium voltage network are performed automatically, if this is configured in the settings and the time interval from the last calculation has elapsed (for more information about general settings, see
7.4.1, Defining automatic function settings).
If a current measurement, an active power (P) measurement, or a reactive power (Q) measurement are connected to a motor node, the change in the motor measurement data affects the load flow calculation results in the radial calculation of WS. If only the current measurement is available, it is used so that the voltage in measurement point is used to estimate the total power (S).
The meshed network load flow is calculated for the total network even if it consists of several isolated networks. An isolated island is a part of network fed by one or several primary feeding transformers but isolated from other network. Several islands can be connected to each other but isolated by open switches. If automatically meshed network analysis is used, the maximum short-circuit currents are calculated for all the isolated islands after a change in switch status (for more information about general settings, see
7.4.1, Defining automatic function settings).

Setting date and time for network analysis
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license is required for a network analysis.
Network analysis in DMS 600 WS is normally used to analyze the real time network state for the most effective and safe use of the network. When using load curves, DMS
600 WS can also simulate the network analysis using the defined date and time. The load flow in DMS 600 WS is calculated using the load information of defined date and time according to the used load curves.
To define the date and time for network analysis:
1.
Select Analyze > Set Calculation Time. The dialog opens and shows the calendar with the defined date and fields with the defined time. The default is the current date and time. The current date is shown in red. The defined date is shown in blue.
2.
Select the date from the calendar with the mouse. Browse months with the arrow buttons or click the month name and select the desired month. Change the year by browsing the months or click the year and insert the desired year.
3.
Insert the exact time of calculation to the Time(hh:mm) fields.
4.
Click Set calculation time to take the date and time into use and close the dialog.
If DMS 600 WS is not in Simulation Mode, it is changed to this state. At the same time the load data of the defined time is loaded and the network analysis is performed with the new load data.
Select Analyze > Back to State Monitoring or click Use present time in the Set calcu-
lation time dialog to take the current date and time into use and calculate the network analysis with the current load data. DMS 600 WS changes back to State Monitoring
Mode. The Use present time button does not change the mode back to State Monitoring
Mode if the mode has been Simulation Mode already before setting the time.

General progress of the MV fault management
This chapter does not apply to the DMS 600 (Base) license.
The Fault Location license is required for fault management.
The progression of fault clearance depends on the use of the automatic fault isolation and restoration function and the type of fault.
A new fault causes automatic zooming into the area of the faulted feeder. Other simultaneous faults are not zoomed, but the faults are processed in the background (for more
information about automatic zooming, see 7.4.1, Defining automatic function settings).
Fault management starts with fault location (for more information about fault location,
see 11.4.1, General about fault location). After fault location, a GSM message about the
outage can be sent to important customers automatically or manually. The default values used in the message are based on the active fault and possible reconfiguration. The default
GSM message is sent to customers without supply.

Fault location
General about fault location
DMS 600 4.2
This chapter does not apply to the DMS 600 (Base) license.
The Fault Location license is required for fault management.
The fault location function deals with permanent feeder faults occurring in radial operated, neutral isolated, compensated or neutral earthed distribution networks. In meshed networks, the fault location works only if the faulted feeder or an opened circuit breaker is feeding a radial branch. Busbar faults (no feeder for an opened circuit breaker) are located in the same way as radial feeder faults.
If there are problems with the MicroSCADA connection, the fault location simulation
Permanent faults in a distribution network are detected by relays connected to Micro-
SCADA. When a permanent fault has occurred, the required fault data collected by
MicroSCADA is automatically sent to DMS 600 WS. The states of the remotely readable fault detectors are obtained from MicroSCADA.
After that, DMS 600 WS automatically starts the fault location function and shows the present topology of the network. DMS 600 WS analyzes the fault data and inferences the most likely fault locations. All line sections that are possible fault locations based on the fault distance calculation are shown on the screen using the alarm color.
Possible fault locations along the feeder in which a fault has occurred are determined on the basis of the following information:
• Fault distance calculation (based on sequence representation, if necessary).
• Fault detector data.
• Type of line sections (underground cable/overhead line).
• Overload conditions for distribution transformers and cables.
The fault location of short-circuits and earth-faults based on the transferred fault detector data can be used in any kinds of networks. However, fault location based only on fault detectors can locate a fault to a feeder zone determined by fault detectors not accurately to a point along feeder.
The fault distance calculation requires fault current or impedance registration, for example, for relays and data transfer from process via MicroSCADA. The fault data needed for the fault location function of DMS 600 WS can be automatically transferred from
MicroSCADA. Only fault detector data that is read on-site has to be updated manually in DMS 600 WS (for more information about fault detectors read on-site, see
11.4.3, Management of on-site readable fault detector state).

1MRS755274
Operation Manual
If data is missing and the fault location cannot be calculated, the faulted feeder is still displayed on the screen with zooming, and the fault management dialog indicates a new fault.
Fault distance calculation
Fault distance calculations cac use the following methods:
1.
Magnitude of short circuit current (A)
2.
Impedance (reactance) from the relay to the fault location
The method using current magnitude can calculate the fault distance in case of 2- or 3phase short-circuits and 1-phase or 2-phase to earth short-circuits in earthed networks.
However, earth short circuits cannot be located if the substation is fed from a loop because the feeding impedance components cannot be determined. In neutral isolated or compensated networks, 1-phase to earth short-circuits cannot be located using the current magnitude method.
The method using reactance from the relay to the fault location can be used in any kinds of networks. The distance to fault can also be calculated in case of 1-phase to earth faults in neutral isolated networks. In these cases the given reactance is the sum of positive and zero sequence reactances. Normally the accuracy of available reactance measurement is lower, especially in compensated networks.
Management of on-site readable fault detector state
This chapter does not apply to the DMS 600 (Base) license.
The Fault Location license is required for fault management.
The states of the remote readable fault detectors are obtained from MicroSCADA but the on-site readable detectors are managed by the user interface of DMS 600 WS.
If there are any faults under fault management in DMS 600
WS, a change of the fault detector state also causes a new fault location function for the active fault to be run again using the new fault detector information.

Operation Manual
To change the operational state of detectors:
1.
Click a fault detector in the network window or on the diagram to open the Fault
detector data form.
2.
Change the operational state of an on-site readable detector by selecting Operated or Non-operated. The network window is updated and a message sent to all instances of DMS 600 WS to read the new fault detector state from the DMS 600 database.
The fault location function for the active fault is run again using the new fault detector information.
The operational time of an on-site readable detector is managed by DMS 600 WS, so that the operational time is always the present time relating to the selection of a state.
If DMS 600 WS is in Simulation Mode (for example, while studying an old repaired fault), you are asked if you want to store the update permanently in the real time DMS
600 database, too. The selection of a state always affects the network model and the fault file under simulation.
Progress of the fault location
This chapter does not apply to the DMS 600 (Base) license.
The Fault Location license is required for fault management.
MicroSCADA detects a fault and switches to DMS 600 SA and DMS 600 WS. When
DMS 600 WS receives information of a new fault, it runs the fault location function. For
more information about settings, see 7.4.1, Defining automatic function settings. When
the fault location function is running, the user interface of DMS 600 WS contains two network windows. The main network window is automatically zoomed to the feeder in which a fault has occurred. The feeders are shown according to the switching state (the feeder that has been faulted is shown with an unsupplied color) and possible faulted line sections are shown with an alarm color in the main network window. Other feeders are shown according to the switching state of the feeders. The bottom-right corner includes the resizable Fault Management dialog box which is the basic dialog box for getting information on faults.
If the fault location function of DMS 600 WS cannot locate the fault definitely ("Fault
not located" text is visible in the dialog), the management of the fault is continued with the functions of the Fault Management dialog (for more information about fault man-
agement, see 11.6.1, Selection of active fault).
If DMS 600 WS is in the Automatic Fault Isolation and Restoration Mode, the Fault
Management dialog is disabled and the Automatic Operation Mode Running dialog is active. For more information about automatic fault isolation and restoration, see

The fault isolation and restoration planning necessitate the definition of fault locations
(for more information about fault location, see 11.4.1, General about fault location).
Fault location can be based on the automatic fault location function or the faulted zone can be defined manually. The definition of the faulted zone for the isolation and restoration planning is done automatically, if the probability of the fault in some remotely controlled zone is larger than the lower limit of the faulted zone and the probability of a fault in other zones is smaller than the upper limit of the other zones (for more information about
faulted zone parameters, see 7.8.2.3, Faulted zone location settings).
Fault isolation and restoration planning generates the switching sequence that takes into account the technical constraints of the network and the protection demands. Voltage drop, short-circuit detection, earth-fault detection, short-circuit capacity and load level for each line section included in the planning are checked (for more information about
switching planning parameters, see 7.8.3, Switching planning settings).

Operation Manual
After Automatic Fault Isolation and Restoration Mode detects a new fault:
1.
DMS 600 WS receives information of a new fault, waits for a delay (defined by
Fault Location Start Delay (s) in DMS 600 NE/Integra) and runs the fault location function automatically.
2.
If DMS 600 WS cannot locate the fault definitely, the management of the fault must be continued manually. For more information about manual fault management, see
11.5.3, General about manual fault isolation and restoration. If DMS 600 WS can
locate the fault definitely to a remotely controlled zone (or a feeder without remotely operated switches), DMS 600 WS automatically starts the fault isolation and restoration planning. The result of the planning is the switching sequence.
3.
The generated switching sequence is automatically executed. After the startup of the automatic sequence, DMS 600 WS presents the status the Automatic sequence
running. If the whole switching sequence was successful, DMS 600 WS waits for the delay (defined by Switching State Update Delay (s) in DMS 600 NE/Integra) and checks that the current switching state is similar to the switching sequence plan.
Only if no errors occur during the sequence, and the two switching states are similar,
DMS 600 WS continues normally and may start another restoration sequence if a new fault appears, otherwise the status will be changed to "Automatic fault isolation
mode interrupted". In the latter case, DMS 600 WS cannot start another sequence before manual resetting by the Reset button in the Automatic Operation Mode
Running dialog. For more information about processing the switching sequence, see System Administration.
4.
After the successful execution of the switching sequence, the fault must be marked as repaired in the Fault Management dialog. If you are using the same workstation, the system assumes Automatic Fault Isolation and Restoration Mode is quitted. The function can also be done with another DMS 600 WS workstation. Click Repaired in the Fault Management dialog to indicate that the active fault has been repaired.

After MicroSCADA detects a new fault, the fault location function runs using the real fault data that is automatically transferred from MicroSCADA and the fault location parameters defined by the administrator. To simulate a real fault, you can select it from the list of all faults.
Changing fault information
This chapter does not apply to the DMS 600 (Base) license.
The Fault Location license is required for fault management.
To change real fault data transferred from MicroSCADA:
1.
Click Fault information in the Fault Management dialog box. The Fault
information dialog box opens showing the detailed information on the active fault.
For more information about fault data, see 11.6.3.1, Base data of fault.
2.
Change the fault information. Here are some notes for the changing:
• Earth short-circuit faults can be selected only if the network is earthed.
• In the case of a permanent fault and final tripping, which normally starts the fault location function, the last measured value of the short-circuit current is used as a default in the fault distance calculation. Generally, an autoreclosing has preceded the final tripping. Therefore, the register also includes the measured values relating to the autoreclosing operation. For simulating the fault location with the fault current of the first circuit breaker opening (that is, when the fault really occurs), the correct value is selected from the buffer dialog box and written in the fault current field.
• Normally fault location uses the feeding network's short-circuit impedance values that are associated with the main transformers. To use alternative switching states in the feeding network, you need different feeding network impedance values. Alternative feeding network impedance values can be used if they are defined (for more information about the definition of alternative network impedance values, see System Administration). If the alternative impedance values are defined, the Fault information dialog contains the
Alternatives box which presents the descriptions of the alternative feeding network for the selected main substation and circuit breaker. Select the desired alternative situation and the corresponding resistance and reactance values. To use the values associated with the main transformers, select Default.
• If resistance or reactance values are changed manually during fault location, they can be saved to the fault file when the defined fault state is "repaired" (will be prompted). These values cannot be saved at the fault simulation.
3.
Click Simulation to locate the fault using the changed data.
You can always retrieve the original values of the real fault from the fault file by clicking

Switching planning
General about switching planning
DMS 600 4.2
This chapter does not apply to the DMS 600 (Base) license.
The Network Analysis license with the Operation Planning sublicense is required for switching planning.
Switching planning functions require the Network Analysis license. The isolation and restoration planning made during the fault management also requires the Fault Location license.
The main functions of switching planning are:
• Isolation and restoration planning can be used in experimental switching planning
(for more information about fault isolation and restoration planning, see
11.5.1, General about fault isolation).
• Maintenance outage planning is used in the planning of switching actions that are needed to disconnect line sections for outages and to restore supply after an outage with as little disturbance to the customers as possible.
•
Contingency analysis by stepping through predefined sequences. The sequences present major outage situations in the network. Measurement value adjustments of load and generation points (motor and generator power changes) can be included into the sequences. Also Analyze Contingency commands can be used in the sequences, and if any violations are found in the network analyses, a report is generated. The report can be set to contain both topology and calculation violations, or only violations during the network calculation.
• Reconfiguration planning helps to find an optimal switching state with minimal losses in the existing load situation.
Automatic planning functions generate the switching sequence which informs about the technical constraints of the network and the protection demands. Voltage drop, shortcircuit detection, earth-fault detection, short-circuit capacity and load level are checked for each line section included in the planning (for more information about switching
planning parameters, see 7.8.3, Switching planning settings). In addition to automatic
switching planning, you can also create a switching sequence manually in DMS 600
WS.
The switching sequence contains the opening and closing of switch devices, simulated power values to motors and generators if contingency analysis was used, and other actions needed during an outage (for more information about the data content of the switching
sequence, see 12.10.1, Plan data). You can modify, simulate and execute switching
sequences that are created manually or with the maintenance outage planning function.

Outage data management
General about outage data management
DMS 600 4.2
This chapter does not apply to the DMS 600 (Base) license.
The Outage Reporting and the Statistics licenses are required for outage data management.
The outage data management requires the Outage Reporting and Statistics license. The
Fault Location, Low Voltage Networks and Operations Planning licenses are needed for the full operation of the function.
The main functions in outage data management are:
• LV network outage reporting
•
MV fault reporting
•
MV maintenance outage reporting
• Reclosing reporting
• Retrieval of customer and MV/LV station specific outage data
• Archiving of outage reports
Reporting fault and maintenance outages
General about reporting fault and maintenance outages
This chapter does not apply to the DMS 600 (Base) license.
The Outage Reporting and Statistics license is required for outage data management.
Outage reporting is used for the reporting of basic outage data and actions during a fault clearance and maintenance outage.
When a fault report is opened for the first time and if Save switchings to fault file is not selected, a dialog box for confirming fault starting and ending times is shown.
Switching data is read from the switching log, and stored to the fault file. For more
information, see 11.1, General about fault management.
DMS 600 WS generates an outage report template. Most of the template's fields are filled in advance on the basis of the executed sequence. You can define the exact MV fault location by pointing the location in the network window before reporting. The system calculates key values of the MV outage on the basis of outage data (for more information

about reporting settings, see 7.8.4, Reporting settings). The operator completes the report
and saves the data into archives for later use.
The fault reporting function is used after the fault has been repaired, the supply is restored and the fault is set to repair. The maintenance outage reporting function is used after the outage has been repaired and supply is restored.
Fault and maintenance outage reports can also be created by defining an interruption area. In this case outage data is not needed.
Outage reporting is performed in the control center. Other workstations can only scan the outage report data. Only a user who has rights to perform the fault management and is responsible for the appropriate fault or maintenance outage can update the fault report data of the outage.
Reporting of LV network outages
This chapter does not apply to the DMS 600 (Base) license.
The Outage Reporting and Statistics license is required for outage data management.
The customer normally notifies about a low voltage network fault. Information about a fault can be saved to DMS 600 WS during the fault. LV outage maintenance data can also be saved using LV network outage management in the same way as in fault cases.
which can be archived in an archive.

Database analysis
DMS 600 4.2
General about database analysis
The database analysis produces summaries and data collections from the network database.
The analysis is based on queries. DMS 600 software contains a default group of queries.
An experienced user can create queries of his/her own using the capabilities of the full version of MS Access (for more information about creating queries, see System
Administration). Simple queries can also be created using the graphical query creation feature in DMS 600.
A query can cover the entire network data or a selected object group. The query filters can contain one or more constraints (for example, manufacturing year before 1970 and the last maintenance made before year 1995) which are then used to filter the data from the database.
The results of queries can be viewed in table format in MS Access. The queries containing coordinate or node code data can be viewed in graphical form in DMS 600.
Any saved queries can be added to DMS 600 menu commands. Reports from the network database can also be run using DMS 600 WS menu commands.
A full or runtime version of MS Access is needed, depending on the covered tasks.
Queries in DMS 600 software
Query results in DMS 600 software
Graphical queries saved in MS Access can be executed in DMS 600. Simple graphical queries can also be created using the functions of DMS 600.
Only graphical queries are shown in DMS 600.
Any saved MS Access queries can be added to the DMS 600 software menu View >
Access Queries as a command (for more information about adding queries to menu, see
14.4, Adding query command to menu ). Select View > Access Queries > "Query
Name" to open MS Access and show the query results in table format (for more information about functions in MS Access, see System Administration).
