CHLORIDE 70-NET

UPS Systems from 10 to 60 kVA

1. Scope

The following specification describes a continuous duty three phase, static,

IGBT Uninterruptible Power System

(UPS). The UPS shall automatically provide continuity of electrical power, within defined limits and without interruption, upon failure or degradation of the commercial AC source. The continuity of conditioned electric power shall be defined by the battery system for the autonomy time period; the battery system will be automatically recharged by the UPS upon restoration of the commercial AC source.

2. System Description

70-NET is an intelligent double conversion UPS, as shown in Figure 1.

The systems shall operate on a DSPbased IGBT inverter. Through Vector

Control technology, the performance of the inverter shall be enhanced and shall be capable of providing reliable, high quality AC power. In order to increase system redundancy, an independent electronic static bypass shall be integrated into the UPS.

By adding system components, such as parallel kits, safety and disconnecting devices, system bypass switches, as well as software and communications solutions, it shall be possible to set up elaborate systems ensuring the complete protection of the supplied loads.

2.1 The system

The UPS shall provide high quality AC power for electronic equipment loads and shall offer the following benefits:

• Increased power quality, for optimal and safe operation of loads.

• Full noise rejection, for complete load protection against upstream network disturbances

• Full compatibility with all types of loads, including heavily non-linear ones

• Power blackout protection in case of power outages

• Full battery care, to preserve the useful life of the battery system

• Transformer-less design, allowing reduced footprint and weight

(galvanic isolation transformers are available as standard options)

The UPS shall automatically provide continuity of electrical power, within the defined limits and without interruption, upon failure or degradation of the commercial AC source. The length of the backup time, i.e. autonomy time in the event of network failure, shall be determined by the battery capacity.

3. General Requirements

3.1 Applied Standards

Chloride is certified by the British

Standard Institution (BSl), as a company with a quality and environmental system in accordance with the ISO

9001 and ISO 14001. 70-NET shall carry the CE mark in accordance with the Safety and EMC Directives

2006/95 (superseding the 72/23 and successive amendments), 89/336,

92/31 and 93/68. 70-NET is designed and manufactured in accordance with the following international standards:

3.3 Neutral/Earth

• IEC/EN 62040-1-1 General and safety requirements

• EN 50091-2 EMC requirements

• IEC/EN 62040-3 Performance and

Operating requirements

3.2 Components and materials

70-NET neutral output shall be electrically isolated from the UPS chassis. 70-NET shall not modify the neutral state. Therefore, the downstream distribution shall be of the same type as the input distribution whilst the upstream neutral is connected to the UPS.

All materials and parts contained within the UPS shall be new and in current production and, to ensure maximum reliability, they shall be used well within the parameters recommended by the supplier.

70-NET must be used in installations with grounded neutral; for further details please contact Chloride

Technical Support (special versions may be used - see Chapter 12).

4. Device Description

In this section the main functional blocks of 70-NET and operating modes of this UPS are described.

4.1 Functional blocks

The UPS shall consist of the following major functional blocks (refer also to

Figure 1):

• AC/DC converter. The rectifier shall be capable of delivering the necessary power to the DC bus to drive the inverter, absorbing virtually only active power from the upstream network (Power Factor

Correction)

• Battery Charger. This device shall be able to completely recharge the battery bank, by delivering DC power to the batteries with a very low voltage and residual current ripple

• Booster. This DC/DC converter will boost the rectifier/battery DC voltage, creating a split DC bus, which will allow the inverter to recreate the AC nominal voltage without the need for an output transformer

• DC/AC converter. The IGBT transformer-less inverter shall be controlled by a Digital Signal

Processor (DSP), see section 4.3

for details

• Static bypass with separate input feeder. The electronic static switch on the reserve supply shall be capable of switching the load from the inverter line to the direct line, and vice-versa, with a Make Before

Break (MBB) transition, either upon manual or automatic command

(see section 4.4 for details)

• Manual maintenance bypass switch.

This manual switch shall allow complete internal maintenance of the unit without interruptions to the load power supply

• Integrated batteries into the UPS cabinet (10 - 40 kVA range) for basic autonomies

• Matching battery cubicles for extended battery autonomies

4.2 Microprocessor diagnostics and control

Control of the power electronics modules will be optimised in order to provide:

• An optimum three-phase supply of the load

• Controlled charging of the battery

• Minimum phase effects upon the upstream supply network

4.2.1 Redundancy, preventative monitoring

In order to maximise the reliability of the system, the control unit shall monitor a wide number of operating parameters of the rectifier, inverter and battery. All the important operating parameters, such as temperature, frequency and voltage stability at the system output, as well as all the load parameters and internal system values shall be continuously monitored and controlled for irregularities. The system shall react automatically prior to a critical situation for the UPS or the load, in order to ensure the supply of the load even in the most critical situations.

Operation and control of the UPS shall be provided through the use of microprocessor controlled logic.

Indications, measurements and alarms together with battery autonomy shall be shown on a back-illuminated graphical

LCD display. The procedures for start up, shut down and manual transfer of the load to bypass and return from bypass shall be described by clear step-by-step actions, reported on the user manual and assisted through the LCD display.

4.2.2 Remote diagnosis and control

Using an advanced remote diagnosis and control system, it shall be possible to remotely monitor and control the UPS from a location such as a service centre in order to maintain the reliability of the system at optimal levels.

CHLORIDE 70-NET

UPS Systems from 10 to 60 kVA

4. Device Description

4.3 Digital Vector Control System

4.4.1.2 Overload

By using digital signal processors

(DSP), 70-NET shall implement the most advanced Digital Vector Control system. Special arithmetic algorithms shall be implemented to ensure quick and flexible processing of measuring data. As a result, controlled variables

4.4 Intelligent Double Conversion operating modes

If the inverter stops, via operator intervention or due to an overload, the UPS automatically transfers to the direct line (if available) without interruption. When the overload ceases, return to the inverter is automatic.

This enables 70-NET to handle the inrush shall be rapidly generated and transferred to the IGBT drivers in

PWM mode (Pulse Width Modulation).

Thus, real time control of inverter current of the load without the need to over-size the UPS. The transfer to direct line is only allowed when voltage and frequency of the mains power supply electronics shall be possible. are within limits. In the event of an

This results in advantages concerning the performance of power components.

Advantages involved shall include:

• Improved short circuit behaviour, since the individual phases can be quickly and individually controlled

• Synchronism or phase angle precision between UPS output and reserve supply even in the event of a overload with an unsuitable mains supply, 70-NET prevents the transfer and the inverter continues to supply the load for a period, depending on the degree of overload. Appropriate visual and audible alarms inform the user of the particular abnormal operating condition.

4.4.1.3 Emergency distorted mains voltage

• High flexibility and reliability in parallel operations. Furthermore, parallel blocks can be placed in different rooms

If the mains supply has failed or is outside tolerance limits, the batteries are used to power the load. The user is alerted to the battery discharge through visual and audible alarms and the battery capacity is displayed on the graphical display. It is possible to extend the autonomy remaining by turning OFF non-essential loads. The warning indicator on 70-NET will display battery operation. 70-NET adopts Intelligent Double

Conversion technology which allows

UPS to operate in double conversion or digital interactive mode according to the selected priority. The UPS will operate as follows:

4.4.1 Double Conversion Mode

4.4.1.1 Normal

4.4.1.4 Return to normal conditions

When the mains power supply returns within tolerance limits, 70-NET resumes normal operation. The battery charger automatically recharges the battery to ensure maximum autonomy in the shortest possible timeframe.

On the basis of the analysis performed, it shall decide whether to supply the load through direct line or conditioned line. This operational mode, which allows significant energy savings by increasing overall UPS AC/AC efficiency, is primarily intended for general purpose ICT applications. However, it does not provide the same output power quality as when the UPS is operated in Double

Conversion mode. Therefore, it shall be necessary to verify whether this mode is appropriate for special applications.

Digital Interactive mode shall not be available for parallel systems.

4.4.2.1 Normal

The operating mode will depend on the quality of the mains during the recent past. If the line quality has remained within permitted tolerance levels, the direct line continuously supplies the critical AC load through the static switch. Control of the IGBT inverter constantly operates and is synchronised with the direct line. In the event of any deviation from the selected input power tolerance levels, this ensures that the load can be transferred to the conditioned line without any break in supply. If the direct line failure rate has reached outside permitted parameters, 70-NET shall supply the load from the conditioned line. The battery charger supplies the energy necessary to maintain the optimal charging level to the battery.

4.4.2.2 Inverter stop or overload

The IGBT inverter continuously supplies the load. The rectifier derives power from the mains supply and converts it into DC power for the inverter. The

AC/DC rectifier corrects the load power factor to a value of >0.95 and, for the 10 - 40 kVA range, also reduces the input current total harmonic distortion (THDI) to a value of less than

8% (at P

OUT

= P

NOM

). The battery charger automatically maintains the battery in a fully charged and optimum operational condition. The IGBT inverter is constantly synchronised to the direct input line, thus allowing load transfer from the inverter to the direct bypass line without any interruption in power to the load in the event of overload or inverter stop.

4.4.1.5 Recharge

Even if batteries are completely discharged, the rectifier/charger shall automatically restart upon restoration of the commercial AC source and shall take over the inverter after a programmable delay. This shall be a fully automatic function and shall cause no interruption to the critical load.

4.4.2 Digital interactive mode

If priority has been set to digital interactive mode, intelligent double conversion technology shall allow 70-NET to continuously monitor the condition of the input supply to ensure maximum reliability for critical users.

If the Inverter is stopped either by the operator or due to an overload, there is no transfer to the conditioned line and the load continues to be supplied by the direct line. Mains voltage and frequency values must remain within the specified tolerance limits. In the event of an overload lasting more than the maximum specified capacity, the load is transferred to the conditioned line, which will supply it for a specific time depending on the level of overload. In the event of an overload and an unsuitable mains supply, 70-NET transfers the load from the direct line to the conditioned line

(assuming 70-NET was operating from direct line) and the inverter continues to supply the critical load for a time that depends on the degree of the overload and the UPS features. Visual and audible alarms alert the user to the problem.

CHLORIDE 70-NET

UPS Systems from 10 to 60 kVA

4. Device Description

4.4.2.3 Emergency (the mains supply has failed or is outside tolerance limits)

If 70-NET supplies the load via direct line and the mains supply reaches outside the tolerance levels (adjustable by software), the load will be transferred from the direct line to the conditioned line.

The load is powered from the mains via the rectifier and inverter, provided the input mains remains within its nominal tolerance. If the input mains is outside these limits, batteries are used to power the load via the inverter. The user is alerted to the battery discharge by visual and audible alarms and the autonomy remaining is displayed on the graphical display. At this time, it is possible to extend the autonomy remaining by turning off non-essential loads.

4.4.2.4 Return to normal conditions

When the mains supply returns to within tolerance limits, 70-NET continues to supply the load via the conditioned line for a period of time dependant upon the direct line failure rate (the conditioned line draws power from the mains not the battery). When the direct line has stabilised, 70-NET returns to normal operation. The battery charger automatically begins to recharge the battery. Consequently, maximum autonomy is guaranteed in the shortest possible time.

from the rectifier by means of battery switches provided in the UPS or in the external battery cabinet. During the maintenance, the UPS will continue to operate and meet the performance criteria specified, with the exception of back-up capability.

4.5 Backfeed protection (from

November 2005)

4.4.3 Maintenance bypass

If for any reason the UPS has to be taken out of service for maintenance or repair, the UPS shall be provided with an internal maintenance bypass switch which enables a load transfer to reserve supply with no interruption in power to the critical load. Bypass isolation shall be complete, all serviceable components such as fuses, power modules etc. shall be isolated.

4.4.4 Operation Without Battery

If the battery is taken out of service for maintenance, it shall be disconnected

This feature shall prevent any potential risk from electric shock on the UPS bypass input AC terminals in the event of failure of the bypass static switch SCR.

The control circuit shall include a contact

(available for the user) which activates an external isolating device, such as an electromechanical relay or a tripping coil, upon backfeed detection. The external isolating device is not included in the

UPS, in compliance with IEC/EN 62040-1.

The external isolating device shall be an air gap isolator, and shall be defined according to clause 5.1.4 of the previously cited standard.

11. Parallel Configuration

The 70-NET series of uninterruptible power systems shall have the capability to be connected in parallel for multi module configurations between units of the same rating. The maximum number of UPS in modular parallel configuration shall be 8. The load sharing shall be equal between the individual UPS systems, at any output load percentage.

The parallel connection of UPS shall increase redundancy (for reliability) and power.

Redundancy

If the installation requires more than one unit in redundant configuration, the power of each UPS should not be lower than P tot

/(N-1) where:

P tot

= Total load power

N = Number of UPS units in parallel

1 redundancy

Under normal operating conditions, the power delivered to the load shall be shared between the number of UPS units connected to the parallel bus. In case of an overload the configuration is able to deliver P ov x N without transferring the load onto the reserve, where:

P ov

= Max overload power of a single UPS

N = Number of UPS units in parallel

In the event of a failure of one of the

UPS units, the faulty unit shall be disconnected from the parallel bus and the load shall be supplied from the remaining units without any break in supply continuity.

Power

It shall be possible to increase the power of the system using a nonredundant parallel configuration

(redundancy coefficient = 0). In this case, all connected UPS units shall deliver the rated power, and in the event of a unit failure or overload the system shall transfer the load to reserve.

The parallel connection of UPS shall improve reliability or the total output power or both. When 70-NET is supplied with the parallel kit option, up to 8 equal UPS units can be operated in parallel for power upgrade or increase of redundancy. This option can also be added on at a later date in the field. It shall consist of one subassembly POB (Parallel Operation

Board) and 25 pole, screened data lines to the neighbouring UPS modules. A multi-module system shall be controlled and monitored automatically by controlling the individual UPS systems (distributed control system). The communication bus which connects the paralleled units shall be arranged as a loop, allowing proper parallel operations even in the case of a single interruption occurring to this bus (firstfailure proof bus). The reserve lines and inverters included in each UPS share the load, at any load percentage.

See Figure 3 for details about the power connections.
