100 kW TACTICAL QUIET GENERATOR SET
OPERATION UNDER USUAL CONDITIONS Continued
PARALLEL UNIT OPERATION (LOAD SHARING) Continued
The ideal load for the generator set is 80% of rated capacity. When operated at less than 80% of
rated load, the diesel engine operates at lower temperatures and burns fuel incompletely resulting in
carbon and moisture in the exhaust and carbon buildup or wetstacking in the engine. To avoid
damage to the engine, if possible, mission loads should be distributed among available generator sets
to achieve an average 80% load on each generator set.
The minimum load that the generator set should be operated at is 25% to 30% of its rated capacity.
Operating at lower loads for long periods of time may damage the engine and cause wetstacking and
damage to the engine. Engines operated at low loads for long periods of time should be operated at
full load for a few hours until the wetstacking residues are burned out. This should be performed
every 300 hours of generator set operation.
Ensure load requirement is equal or below combined rated capacity of generator sets. If load is greater than combined
capacity of the generator sets that are being paralleled, the generators will overload and the TQG could be damaged.
Determine voltage requirements of load. Ensure voltage Reconnection Boards (WP 0005, Table 9) of generator sets
match voltage requirements of load (WP 0006, Table 1).
Notify maintenance to change Reconnection Board and to reprogram the GSC and DVR to obtain required output.
Inside EMCP control box assembly, set ISOCHRONOUS/DROOP switch to DROOP for all generators to be paralleled
Identify one generator set as TQG No. 1 and the other as incoming TQG No. 2. If a 200 kW TQG is being paralleled
with a 100 kW TQG, designate the 200 kW TQG as No. 1.
On each generator set, set ENGINE CONTROL to OFF/RESET, Battery Disconnect Switch to OFF, and DEAD
CRANK SWITCH to OFF.
Verify that generator sets are grounded. Ground each generator set (see WP 0006 00-2).
Common ground should be used.
