• Provides for single unit standalone operation, island mode paralleling and load sharing with other power
modules, and single unit-to-utility mode paralleling
for base load control (with open transition between
paralleling modes)

Single Unit Standalone and Multi-unit
Island Operation
• Utility standby mode (normal)
– The utility is providing power for the plant loads
– The PM generator breaker is open
– The PM is in automatic standby mode to respond to
a utility failure
• Emergency mode (emergency)
– Utility failure
a. The customer protective relaying senses a utility
abnormal condition
b. A run request is sent to the PM generator plant
c. The first PM generator to reach rated voltage and
frequency is closed to the bus
d. In multi-unit island mode, the remaining PM
generators are paralleled to the bus as they
reach rated voltage and frequency. This function
is performed via the lead unit select jumper and
interconnect wiring connected between the
power modules.
e. Plant load is transferred to the power modules,
which share load equally via load share lines.
Single Unit Base Load Operation
• Utility mode (normal)
– The utility is providing power for the plant loads
– The PM is in auto mode and the generator breaker
is open
– The PM is interconnected to the utility breaker aux
contact, lead unit jumper is not installed and load
share lines are not connected
– The paralleling controls automatically detect utility parallel mode when the utility aux contact is closed
• Base load mode
– Unit receives remote run request and starts
– Unit reaches rated voltage and frequency
– UMR performs sync-check to permit generator
breaker to close
– Unit ramps to base-load set point at programmed
ramp time
– Unit continues to run until remote run request is
removed or unit is stopped at control panel

MG 1-33.
Prime — Output available with varying load for an
unlimited time. Average power output is 70% of the
prime power rating. Typical peak demand is 100%
of prime rated ekW with 10% overload capability for
emergency use for a maximum of 1 hour in 12. Overload
operation cannot exceed 25 hours per year. Prime power
in accordance with ISO3046. Prime ambients shown
indicate ambient temperature at 100% load which results in a coolant top tank temperature below the
alarm temperature.
Standby — Output available with varying load for the
duration of the interruption of the normal source power.
Average power output is 70% of the standby power
rating. Typical operation is 200 hours per year, with
maximum expected usage of 500 hours per year.
Ratings are based on SAE J1349 standard
conditions. These ratings also apply at ISO3046
standard conditions.
Fuel rates are based on fuel oil of 35º API [16ºC (60ºF)] gravity having an LHV of 42 780 kJ/kg (18,390 Btu/lb)
when used at 29ºC (85ºF) and weighing 838.9 g/liter
