1.UPS definition

1.1.Purpose

The purpose of this specification is to define the design, manufacture and testing characteristics required in view of supplying, putting into operation and maintaining an Uninterruptible Power Supply (referred to as a UPS hereinafter).

The UPS shall be designed to supply dependable electric power to:

1.2. Brief description

The UPS shall be a single UPS, operating in double-conversion mode (also called on-line mode); it shall be a VFItype UPS (as per standard IEC 62040-2), made up of the following components, described in detail in this specification:

ωRectifier

ωBattery charger

ωInverter

ωBattery

ωAutomatic bypass (via a static switch)

ωManual bypass (for maintenance)

ωUser and communications interface

ωBattery management system

ωAny and all other devices required for safe operation and maintenance, including circuit breakers, switches, etc.

2.Operating principles

The UPS shall operate in double-conversion mode as indicated below.

2.1. Normal operation

(normal AC source available)

The rectifier shall supply the inverter and the charger with DC current. The inverter shall continuously supply the load with backed up electrical energy and the charger shall float charge the battery.

2.2. Operation on battery power

(normal AC source not available or outside tolerances)

Upon failure or excessive deterioration of the normal AC source, the inverter shall continue to supply the load from battery power without interruption or disturbance, within the limits imposed by the battery backup time.

2.3. Battery recharging

(normal AC source restored)

When the normal AC source is restored, the rectifier shall again power the inverter, without interruption or disturbance to the load, while the charger automatically recharges the battery.

2.4. Transfer to bypass AC source

In case of a major overload or if the UPS shuts down, the static switch shall instantaneously transfer the load, without a break in the supply of power, to the bypass AC source if it is available and within tolerances. Transfer of the load back to the UPS output, synchronized with the bypass AC source, shall be automatic or manual. During transfer, the load shall not suffer an outage or disturbance in the supply of power.

On request, the UPS system may automatically transfer the load with a micro-interruption (adjustable from 15 to 1000 ms) if a major fault occurs on the UPS system and if synchronization with the bypass source has not been established.

2.5. UPS maintenance

For maintenance purposes, the UPS shall include a mechanical manual bypass system with one-button operation. For personnel safety during servicing or testing, this system shall be designed to isolate the UPS while continuing to supply power to the load from the bypass AC source.

ω Steady-state conditions

Variations in the rated voltage shall be limited to ± 2% for a balanced load between 0 and 100% of the rated load, whatever the voltage level on the normal AC source and the DC voltage level, within the limits defined in sections 4.1 and 5.1.4.

To that end, during normal operation, a synchronization system shall automatically limit the phase deviation between the voltages to 3 degrees, if the bypass source frequency is sufficiently stable (within adjustable tolerances of 0.5% to 8% with respect to the rated frequency).

ω Synchronization with an external source

It shall be possible to synchronize with all types of external source.

ω Autonomous operation following loss of synchronization with bypass power

When the bypass source frequency deviates beyond these limits, the inverter shall switch over to free-running mode with internal synchronization, regulating its own frequency to within ± 0.02 Hz. When bypass power returns to within tolerances, the inverter shall automatically resynchronize.

ω Variation in frequency per unit time

To avoid transmitting to the inverter any excessive frequency variations on the bypass AC source when it is within tolerances, inverter frequency variations per unit time (dF/dt) shall be limited to 1 Hz/s or 2 Hz/s (user defined).

5.3.4. Overload and short-circuit capacity

The UPS shall be capable of supplying for at least:

ω10 minutes a load representing 125% of the rated load

[290 / 235 / 277 / 230 / 234 / 245% ] ... for 150 ms to allow highly disturbed transient operating states without transferring the load to the bypass.

ωThe overload capacity shall be capable of taking into account temperature conditions for more than ten minutes, by allowing a continuous, 10% overload when the temperature is less than or equal to 20°C.

5.3.5. Higher power ratings for lower temperatures

5.4. Automatic bypass

5.4.1. Load transfer to the automatic bypass

The UPS shall be equipped with an automatic bypass comprising a static switch. Instantaneous transfer of the load from the inverter to bypass power and back shall take place without a break or disturbance in the supply of power to the load, on the condition that the bypass source voltage and frequency are within the tolerances specified in section 4.2 and that the inverter is synchronized.

Transfer shall take place automatically in the event of a major overload or an internal inverter fault. Manually

Edition - 01/2010

Single UPS spec - p. 5

Specification guide

Single UPS, three-phase, 160 to 500 kVA (cont.)

initiated transfer shall also be possible.

5.4.2. Static-switch protection

The static switch shall be equipped with an RC filter for protection against switching over voltages and lightning strikes.

5.4.3. Static-switch withstand

For the specified power rating of …[ 500 / 400 / 300 / 250 / 200 / 160 ]… kVA, the static switch shall be capable of handling an over current of …[ 16 / 16 / 21 / 25 / 18 / 23 ]…. times the rated current of the UPS to facilitate discrimination within the electrical installation.

5.5. Discrimination and short-circuit capacity

If the bypass power is within the tolerances specified in section 4.2, the presence of the static switch shall make it possible to use the short-circuit power of the bypass source to trip the downstream protection devices of the inverter.

To ensure tripping in a selective manner, the available power shall be sufficient to trip protection devices with high ratings (circuit breaker rated In/2 or UR fuses rated In/4, where In is the rated inverter current).

If the bypass source is outside the specified tolerances, the inverter on its own shall, for the same discrimination requirements, be capable of tripping circuit breakers rated In/2 or UR fuses rated In/4, irrespective of the type of short-circuit.

5.6. System earthing (grounding) arrangements (SEA)

The UPS shall be compatible with the following system earthing arrangements (SEA):

ωUpstream source SEA: …[TT/ IT / TNS / TNC]…

ωDownstream installation SEA: …[ TT/ IT / TNS / TNC ]
