Parallel UPS, three-phase, 250 to 3000 kVA*
* Power rating for an N+1 redundant configuration
2 - Operating principle
The double-conversion UPS (also called on-line) shall operate as defined below.
2.1 - Normal operation
(normal AC source available)
The rectifier supplies the inverter with DC current while the charger simultaneously float charges the battery. The load is continuously supplied with dependable electrical power by the inverter.
() for parallel connection with a centralized bypass cabinet, up to six units)
A current-loop system shall ensure automatic distribution of the total load between the various parallel-connected units.
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 specified battery backup time.
2.3 - Battery recharge
(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 - Parallel operation with redundancy
………………………………………………………………………………………………………………………………….
() without redundancy)
The system shall not be redundant. The [ 2 / 3 / 4 ] UPS units must operate in parallel to supply the load. Shutdown of one unit shall result in transfer to
…[ the various static bypasses, connected to the same bypass AC source ] …[ the centralized bypass ]
…………………………………………………………………………………………………………………………………..
() with redundancy)
The units shall operate in parallel and redundantly, with the load shared equally between the units. Redundancy shall be of the "n+1" (or n+2) type, i.e. "1" (or 2) units shall be redundant in the total of n units. If a major fault occurs on a unit, it shall automatically disconnect.
If the remaining unit(s) are sufficient to supply the load, it/they shall remain in operation.
If the total available power is insufficient, the load shall be automatically transferred, without interruption, to the bypass AC source, if it is within tolerances.
…………………………………………………………………………………………………………………………………..
2.5 - Transfer to bypass AC source
In the event of an overload exceeding system capabilities or UPS shutdown, the static bypass switch shall instantaneously transfer the load to the bypass AC source without interruption, on the condition that bypass power is available and within tolerances.
…………………………………………………………………………………………………………………………………..
() for parallel connection with an external maintenance-bypass cabinet, up to four units)
During transfer, the system shall simultaneously switch the static switches.
…………………………………………………………………………………………………………………………………..
() for parallel connection with a centralized-bypass cabinet, up to six units)
Transfer shall be carried out by the common static bypass in the centralized-bypass cabinet, with simultaneous orders to the UPS units.
………………………………………………………………………………………………………………………………….
Transfer of the load back to the UPS-unit output, synchronised 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 if a major fault occurs on the UPS system and if synchronisation with the bypass source has not been established.

2.6 - UPS maintenance
For maintenance purposes, all electronic components shall be accessible from the front of the UPS. In addition, a manually operated mechanical bypass system shall be:
…………………………………………………………………………………………………………………………………..
-Built into each UPS unit () for a two-UPS system with active redundancy)
…………………………………………………………………………………………………………………………………..
-Installed separately in the external maintenance bypass cabinet () with external maintenance-bypass cabinet)
…………………………………………………………………………………………………………………………………..
-Installed separately in the centralized bypass () with centralized-bypass cabinet).
This system shall be designed to isolate the UPS while continuing to supply power to the load from the bypass AC source. The UPS shall also include a device making it possible to isolate the rectifiers and the chargers from the normal AC source.
2.7 - Battery maintenance
For safe maintenance on the battery, the system shall include a circuit breaker to isolate the battery of each parallel-connected UPS unit from the rectifier, the corresponding charger and the inverter. When the battery is isolated from the system, the UPS shall continue to supply the load without interruption or disturbance, except in the event of a normal AC source outage.
2.8 - Cold start (normal AC source absent)
The battery of each unit shall be capable of ensuring UPS start-up even if normal AC power is not available and continuing operation within the specified back-up time (start on battery power shall be possible on the condition that the system was already started with AC power present).
3 - Sizing and general characteristics
3.1 - Technology
Each unit in the UPS system shall be based on IGBT technology with built-in thermal monitoring and a high freefrequency chopping mode to dynamically optimise efficiency and power quality.
3.2 - Rating
The UPS system shall be sized to continuously supply a load of kVA, at a power factor (pf) of 0.8.
It shall be made up of ...[2 / 3 / 4 / 5 / 6]... UPS units, each with an identical rating of ...[ 250 / 300 / 400 / 500 / 600]... kVA.
The total installed power rating shall thus be kVA. ...[Consequently, 1 (or 2) unit(s) may be redundant.]
3.3 - Battery backup time
The battery backup time in the event of a normal AC source outage shall be _______ minutes, for a load power factor of 0.8.
Battery service life shall be equal to at least …[ 5 / 10 ]…years. It shall be selected and sized correspondingly, for a load power factor of 0.8.
3.4 - Types of loads accepted
The UPS shall accept high crest factors (3:1) without derating to ensure correct operation with computer loads. The total harmonic voltage distortion at UPS output (THDU downstream) shall respect the following limits:
ωTHDU downstream ph/ph and ph/N ≤ 4% for linear loads;
ωTHDU downstream ph/ph and ph/N ≤ 4 % for non-linear loads.
