A new system-level control
for parallel operation of multiple generator sets can help ensure emergency
power for process facilities, including water treatment plants.
Cummins Power Generation, Minneapolis,
a manufacturer of power generation systems, says its DMC 1500 Paralleling
System has microprocessor-based control technology with icon-based GUI to
maximize user-friendliness. The system consists of a PowerCommand system-level
digital master control integrated with custom-engineered switchgear. The DMC
1500 communicates directly with the generator set and transfer switch controls
for seamless integration.
Paralleling systems are
offered for low- or medium-voltage applications. Typical emergency power
applications, DMC 1500 systems can also be used for prime power at remote
locations, such as mining facilities, where utility power is unavailable or
Power transitions can be
open or closed, in either fast (100 ms) or gradual ramping mode. The system
includes utility paralleling functions for peak-shaving, base-loading and load
add/load shed sequence control. The standard DMC 1500 accommodates four
generators and can be expanded for up to eight generators.
A trained technician can
perform all setup and service functions, including diagnostics, software
upgrades and hardware upgrades. The standardized hardware layout, wiring
harnesses and jack/plug connections simplify any required hardware servicing.
The touch-screen user
interface is available in seven languages. The DMC 1500 system can be ordered
with either UL/CSA or IEC/CE certification, and seismic certification.
