General Description

The 0.2 kW Protective Relaying Training System is a complete program that extends training in protective relaying beyond the operation and calibrations of individual relays into broader circuit applications. The program provides hands-on training at the system level in Generator Protection, Transformer Protection, and

Induction Motor Protection.

The 0.2 kW Protective Relaying Training System consists of several modules, which can be divided into five groups: Common Electrical Modules, Power System Modules (Series 3700), Protective Relaying Control Station,

Protective Relays (Series 3800), and Additional and Optional Equipment. These modules are described in detail below:

Common Electrical Modules – Power supply, synchronous generator, induction motor, prime mover / dynamometer, resistive loads, voltmeters, ammeters, and others. Most of these modules are part of the 0.2 kW

ElectroMechanical System (EMS), Model 8001 or 8006.

Power System Modules, Series 3700 – Modules specially designed for training in the protective relaying area, including current transformers, voltage transformers, power transformers, source impedances, a transmission grid, and others. These modules are designed to be installed in an EMS workstation.

Protective Relaying Control Station – A mobile rack for protective relay operation, including a dc power supply, dc control relays for system studies, and an interconnection panel to facilitate connection of the protective relays to the system to be protected.

Protective Relays, Series 3800 – Selection of protective relays. Each relay is mounted on a metal panel which facilitates relay installation in the Protective Relaying Control Station. Each relay panel is equipped with fault switches that allow fault insertion for troubleshooting at the system level. The following types of protective relays are available: undercurrent/overcurrent, undervoltage/overvoltage, synchronism check, underfrequency/over-frequency, phase balance, phase sequence, reverse power, and power factor.

Additional and Optional Equipment – Various modules, such as distribution busses, a ring bus, transmission lines, distribution transformers, protective relays, and reactive loads are available. These modules can be added to the basic 0.2 kW Protective Relaying Training System to allow the instructor to create more elaborate hands-on exercises.

The 0.2 kW Protective Relaying Training System courseware consists of a student manual and an instructor guide. The student manual is divided into several units, each consisting of a series of hands-on exercises dealing with one of the fields of protective relaying mentioned above. Each exercise provides a clearly stated objective, a discussion, textbook references, a summary of the exercise procedure, a detailed exercise procedure, a conclusion, and a set of review questions. A ten-question test at the end of each unit allows the student to verify what was learned in the unit. Completion of some exercises in the student manual requires a digital storage oscilloscope and a digital multimeter, which must be purchased separately.

The instructor guide contains the practical results as well as the answers for each hands-on exercise in the student manual. It also contains the answers to the unit test questions in the student manual. The reference textbook provides more elaborate discussions of the theory presented in the student manual.

The prerequisites for the 0.2 kW Protective Relaying Training System include: completion of a course in relay operation and calibration, and completion of a course in electric power technology that covers electric power generation, power transformers, and induction motors.

The modular structure of the 0.2 kW Protective Relaying Training System, together with the subdivision of student manuals into topical units, enables instructors to choose equipment that matches their budgets while progressively enhancing their systems over time.

For power utility users, it is possible to combine their own protective relays with a selection of modules from the

0.2 kW Protective Relaying Training System to obtain equipment setups that correspond to existing one-line and three-line diagrams.

Protective Relaying Control Station

3806-40

The Protective Relaying Control

Station is a standard 48 cm (19 in) rack, mounted on castors, that forms the basis of a typical protective relaying control station. Two sets of dc control relays, a dc power supply, and an interconnection panel are mounted on the rack.

The two sets of dc control relays (six relays per set) allow basic contacts of protective relays (either normally open or normally closed contacts) to be converted into multiple normally open

(NO) / normally closed (NC) contacts to actuate ac circuit breakers

(contactors) in the electrical power system. Two of the dc control relays have adjustable time delay. The dc power supply is used to energize the relay coils.

The interconnection panel consists of three sets of twelve 4 mm safety banana jacks mounted on a standard 48 cm (19 in) panel. Three multiple contact connectors, also mounted on the panel, allow connection of cables from the Interconnection Module, Model 3787.

A set of metal rails and three standard 48 cm (19 in) blank panels are supplied with the Protective Relaying

Control Station. The metal rails are used to mount the protective relays in the control station. Customers can use the three blank panels for mounting their own protective relays in the control station.

Resistive Load

8311-00

The Resistive Load consists of a halfsize EMS module housing nine wirewound power resistors arranged in three identical groups. Each group consists of three resistors connected in parallel that can be switched on or off with toggle switches to obtain various resistance values. This allows the total (equivalent) resistance of each group to be increased or decreased by steps. Six safety banana jacks on the module front panel provide access to each resistor group. The three resistor groups can be connected separately for operation in three-phase circuits. Also, the three resistor groups can be connected together for operation in single-phase circuits.

The Resistive Load is commonly used in conjunction with other basic load modules, like the Inductive Load,

Model 8321, and the Capacitive Load, Model 8331, to experiment with the effects of different types of load on a circuit.

The Power Supply cannot supply all the amounts of current indicated by the current ratings on its front panel at the same time. The current indicated for the fixed ac three-phase output section can only be obtained if no current is drawn from any other section, because this section is protected by the main circuit breaker common to every section. If currents flow in other sections, the available current for the fixed ac three-phase output section decreases. The variable ac output section and the variable dc output section are protected by a common set of circuit breakers placed after the fixed ac three-phase output section, which means that the current capacity has to be shared between the two sections. For instance, if current of the variable dc output section is at 70% of its nominal value, current drawn from the variable ac output section should not exceed 30% of its nominal value. The fixed dc output section is also protected by circuit breakers placed after the fixed ac three-phase output section.

Power Diodes

8842-10

The Power Diodes consists of six power diodes mounted in a half-size

All the anodes and cathodes of the diode are terminated on the front panel by color-coded, 4 mm safety banana jacks. The diodes are interconnected in three groups of two, i.e., one group for each phase of the power supply. To reduce the number of external connections on the front panel, the upper cathodes can be connected together as well as the lower anodes, through the use of a toggle switch.

In the Power Supply mode, the unit becomes a four-quadrant power supply that can act as a dc voltage source, dc current source, ac power source, etc.

In each operating mode, key parameters related to the selected function are displayed. Speed, torque, mechanical power, and energy are displayed in the Dynamometer mode while voltage, current, electrical power, and energy are displayed in the Power Supply mode. Optional functions, such as a small wind-turbine emulator, a hydraulic turbine emulator, a solar panel emulator, battery chargers, an SDK (Software Development Kit) etc., can be added to the standard functions to further enhance the training possibilities of the Four-Quadrant

Dynamometer/Power Supply.

Two modes are available to control the function which the Four-Quadrant Dynamometer/Power Supply performs: Manual and Computer-Based.

In the Manual control mode, the module operates as a stand-alone unit, and the function performed is selected, set, and monitored using front-panel mounted controls and display. This mode provides access to all basic functions. In the Computer-Based control mode, the function performed by the module is selected, set, and monitored using the LVDAC-EMS software. In this mode, communication between the Four-Quadrant

Dynamometer/Power Supply and the host computer running the LVDAC-EMS software is achieved through a

USB connection. This mode provides access to all basic functions, as well as to additional advanced functions.

Workstation

(Optional)

8134-20

The Workstation is a fully assembled workstation that serves the same purpose as the Mobile Workstation,

Model 8110-2, but has no storage cabinet or pull-out work surface. This workstation is intended for use on a bench (not supplied) and is fitted with wooden feet to protect the bench top.

Alternatively, this workstation can be mounted on either a Mobile Storage

Cabinet, Model 89117-1, to make a

Mobile Workstation, Model 8110-2, or on a Mobile Base, Model 88863, to make a mobile workstation without storage cabinet. In that case, it is possible to mount and lock a second

Workstation, Model 8134-2, on top of the first Workstation to double the space available for EMS modules.

The Workstation consists of three rows of compartments designed to house EMS modules. Two of these rows have full-height compartments while the other row has half-height compartments. Each row of full-height compartments can accommodate up to three full-size EMS modules or six half-size EMS modules whereas the row of half-height compartments can accommodate up to three half-size EMS modules.

Module Installation

The EMS modules are guided into position along stainless steel guide rails. Separators between each bay of the workstation ensure perfect alignment of the EMS modules and allow their easy insertion in the workstation. A holding mechanism ensures that each EMS module stays in place once it is installed in a compartment of the workstation. Front-mounted push levers allow all EMS modules on a single row to be released for easy removal.



Safety Padlock Bars



Six holes in the rear panel of the workstation allow connection to a power supply, as well as the connection of 2 kW machines to their interconnection modules. Assembly of the workstation before painting ensures that each

EMS module in the workstation is correctly grounded.

Inductive Load

(Optional)

8321-00

The Inductive Load consists of a halfsize EMS module housing nine ironcore power inductors arranged in three identical groups. Each group consists of three inductors connected in parallel that can be switched on or off with toggle switches to obtain various inductance values. This allows the equivalent inductance of each group to be increased or decreased by steps. Six safety banana jacks on the module front panel provide access to each inductor group. The three inductor groups can be connected separately for operation in three-phase circuits. Also, the three inductor groups can be connected together for operation in single-phase circuits.

A permanently-connected discharge resistor reduces the voltage across the terminals of each group of capacitors to 5% of the applied voltage within 15 seconds after the load is disconnected from the supply. The

Capacitive Load may be used with both dc and ac power.

The Inductive Load is commonly used in conjunction with other basic load modules, like the Resistive Load,

Model 8311, and the Capacitive Load, Model 8331, to experiment with the effects of different types of load on a circuit.
