Compact medium and high voltage
generators for data centers
Data centers are extremely
demanding in terms of thereliability and quality of their power
supplies. High reliability andexcellent harmonic performance
make ABB’s compact medium andhigh voltage generators for diesel
and gas engines an ideal solution
for standby power at data centers.
In some cases, these generators
are also being used for continuous
power at data centers.

medium and high voltage
synchronous generators
offer maximum reliability
for data centersReliability and low harmonics
Reliability is essential for data centers, and for
maximum reliability ABB’s compact medium andhigh voltage synchronous generators feature form
wound windings and vacuum pressure impregnation(VPI) for both the stator and rotor. The advanced
VPI insulation system gives the windings added
strength to withstand vibration, and mechanicaland electrical stresses. Since the mid-1970s VPI has
proven itself in tens of thousands of generatorsthat are operating successfully all over the world.
High performance PMG excitation, supplied as
standard, further boosts reliability by ensuring
sufficient magnet power at power-up.

—01

A key way to improve the quality of an electricity
supply is to reduce its harmonic content. As standard, ABB supplies the generators with a 5/6
winding pitch, which reduces the most significant(5th and 7th) harmonics to minimal levels. At the sametime the 5/6 winding pitch increases the generators’
overall efficiency, which enables them to be built ina smaller size for each given output level. ABB canalso supply generators with a 2/3 winding pitch forcases where the neutral point is direct earthed.
This eliminates the 3rd harmonic.

An analog AVR is provided as standard, with ABB’sadvanced UNITROL® digital AVR available as anoption for optimal stability.

The generators are compact and easy to install.
The exciter and PMG are built in, and the main andauxiliary terminals and AVR are all integrated.

The open air cooled, 4- and 6-pole generators
are supplied in frame sizes 500 – 630. They cover thepower range 0.9 – 7.3 MVA at voltages of3.3 – 13.8 kV, 50 and 60 Hz. The insulation is class H,
with utilization as class F in versions optimized forcontinuous duty at data centers.
The cost-effective generators are pre-engineered,enabling fast delivery. Their high efficiency reduces
fuel consumption for a low overall cost ofownership.

Optimized for data center operation
Five 10.5 kV generators have been optimized fordata center operations. These generators are available in frame sizes 500 and 560 and cover outputs in
the range 1.75 – 2.75 MVA (continuous duty rating) at
10.5 kV, 50 Hz. The insulation class is H and temperature rise F. These generators can be used for both
continuous and standby operation. Other voltage
and powers are available upon request.

Like all ABB products, the compact medium
and high voltage generators are backed by theglobal ABB support network, which includes over60 service centers and more than 150 authorized
service providers worldwide. Round-the-clock
access to spares, repairs and replacements helps
customers to minimize downtime and reduce
their cost of ownership.
