Generator Operation
Load Division and Speed Droop (If
Equipped)
Once two units have been paralleled, the unit’s share
of the kW load is determined by the control setting.
If two units of the same capacity and the same
characteristics have the same control settings, the
units will share the load equally. The total load must
not exceed the capacity of the one engine.
In order to transfer the load from one engine to
another engine, use the following procedure:
1. Increase the speed control of one unit in order to
increase the load.
2. Reduce the speed control of the other unit in order
to decrease the load on that unit.
3. Raise the speed control or lower the speed control
of both units in order to change system frequency.
Stopping
In order to remove a generator from the line, perform
the following procedure.
1. Check the load. The load must be less than the
rated capacity of the remaining units.
2. Be sure that the neutral of one of the remaining
units is grounded.
3. Remove the load from the outgoing unit. See
the Parallel Operation, “Load Division - Speed
Droop”. The amperage may never go to zero due
to circulating currents.
4. Open the circuit breaker.
5. Allow the engine to cool for five minutes.
6. Stop the engine.
Circulating Currents
Understanding the circulating currents becomes
very important when you parallel the units. These
circulating currents are flowing between generators
in parallel operation. The circulating currents
are caused by voltage differences between the
generators. The circulating currents are not doing
useful work. The amount of the circulating current can
be determined by subtracting the amperage which is
going to the load from the total generator amperage.
The circulatin
gcurrentmaybeashighas25
percent of rated amperes with cold generator sets.
Such current may not even be considered harmful.
The total gene
rator current should not exceed the
amperage rating.
As the genera
tors warm, the circulating currents will
decrease. The ammeter readings should decrease
slightly, but the voltage meter readings should remain
constant.

Initial Start-Up
Before the initial start-up, perform the megohmmeter
test on the main stator winding. Refer to the Special
Instructio
n, SEHS9124, “Cleaning and Drying of
Electric Set Generators” for the procedure.
Starting
1. Make all pre
liminary engine starting checks.
2. Be sure that the main circuit breaker or the line
circuit bre
aker is open.
3. Start the engine. Allow the engine to warm up.
4. Adjust to the full load engine speed.
5. Close the m
ain circuit breaker.
6. Apply the load. Do not try to apply the full load.
Apply the l
oad in increments in order to maintain
system frequency at a constant level.
7. Readjust t
he governor for rated frequency.
Stopping
1. Removetheloadinincrements.
2. Open the circuit breaker.
3. Allow the e
ngine to run for five minutes in order
to cool.
4. Stop the en
