Bus Arbitration (HWDBA) to allow first unit
up to voltage and speed to be first unit to
connect to a dead bus

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
LEHX0028-01
b. A run request is sent to the PM generator
plant
c. The first PM generator to reach rated
to 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
