2: Description
The high power factor presented by the UPS on the incoming mains supply minimises cabling and fusing
costs due to the resulting lack of reactive power consumption. This, together with the accompanying low
harmonic currents, provide the following benefits:
• No additional losses in wires and cables.
• No extra heating of transformers and generators.
• No over sizing of generators.
• No false circuit breaker tripping and malfunction.
• No erratic operation of computers, telecommunication, monitors, electronic test equipment etc.
• No resonance with power factor correction capacitors.
2.4.3 Flexible battery management (FBM)
This equipment employs a flexible battery management which avoids premature deterioration of battery life
by advanced management of battery charging and preventive failure diagnostics.
The major benefits are:
• AC-ripple free battery charging due to a dc-dc charger separated from the rectifier and inverter.
• Wide range of number of battery blocks (30-50 blocks of 12V; depending autonomy times).
• UPS's wide input voltage operating window extends the battery life due to fewer discharge cycles.
• Battery discharge protection caused by load jumps.
• Proactive battery protection from false manipulations and inadequate charging voltages.
• Proactive battery failure detection thanks to Advanced Battery Diagnosis (ABD) - Algorithm.
• User selectable battery tests.
• Optional temperature compensated charging to enhance battery life.
2.4.4 Decentralized Parallel Architecture (DPA)
In a ‘redundant’ parallel UPS system the UPS modules are linked together in parallel so that in the event that
one module fails the others can automatically sustain the load supply.
A ‘parallel redundancy’ configuration is achieved by having a random or fixed
master-slave
relationship
among the UPS modules whereby the
master
logic gives out individual commands to all the
slave
units.
Unfortunately, in some designs this can lead to a single-point-of-failure for the entire system if the master
logic or communication to the slaves fails.
The PowerWAVE 9000 DPA system features DPA paralleling technology that provides
n+x
redundancy
without introducing a single-point-of-failure. The modules utilizing the DPA technology are completely
autonomous by means of individual power units, bypasses, CPUs, control panels and separate battery
configuration.
DPA technology uses
multi-master
logic with separated independent regulation and logic buses to maintain
the highest system availability.
This unique decentralized design:
• enables a parallel redundant system providing 100% conditioned power at all times.
• eliminates the system-level single point of failure inherent in traditional parallel UPS
• exponentially increases the reliability of the overall system.
• allows up to ten UPS cabinets to supply the same load in
parallel
and
redundant
configuration.
