PARALLEL UNIT OPERATION (LOAD SHARING)
The following method of parallel operation will be used to share the load between two or more generator sets. Additional
generator sets can be added as necessary by following the same procedures. The generator to be brought on line, also
called the incoming generator, is designated TQG No. 2. MEP-809A (PU-809A) (200 kW TQG) and MEP-807A
(PU-807A) (100 kW TQG) generator sets have the same controls and operating systems. These generator sets may be safely
paralleled.
The paralleling procedures describe three different modes of operation: AUTO mode, SEMI AUTO mode, and
PERMISSIVE mode. AUTO mode is the preferred mode of operation and requires the least operator action. SEMI AUTO
mode allows the operator to check anything or make manual adjustments prior to connecting generator sets in parallel.
SEMI AUTO mode may be used if the operator has trouble paralleling the generator sets automatically. PERMISSIVE mode
requires the operator to manually synchronize the generator sets prior to paralleling, using the displays on the GSC and
control knobs on the EMCP. PERMISSIVE mode is useful for troubleshooting (WP 0005 00-2).
Pre-Operation
WARNING
Metal jewelry can conduct electricity and become entangled in generator set components. Remove
all metal jewelry when working on generator set. Failure to comply can cause injury or death to
personnel.
High voltage is produced when this generator set is in operation. Make sure unit is completely shut
down and free of any power source before attempting any repair or maintenance on the unit.
Failure to comply can cause injury or death to personnel.
High voltage is produced when the generator set is in operation. Never attempt to start the
generator set unless it is properly grounded. Failure to comply can cause injury or death to
personnel.
Before making any connections for parallel operation or moving a generator set that has been
operating in parallel, ensure there is no input to the load board and the generator sets are shut
down. Failure to comply can cause injury or death to personnel by electrocution.
DC voltages are present at generator set electrical components even with generator set shut down.
Avoid shorting any positive with ground/negative. Failure to comply can cause injury to personnel
and damage to equipment.
CAUTION
Ensure generator sets are the correct size and model before attempting parallel operation.
MEP-809A (PU-809A) (200 kW TQG) and MEP-807A (PU-807A) (100 kW TQG) generator sets may
be paralleled.
When two or more generator sets are combined their total capacities must be greater than the
demand of the electric load. If generator set capacities are not rated to support the load drawing
power from them, damage to equipment may result.
