Figure 2-2. Droop Contact and Circuit Breaker Auxiliary Contact
Droop or Baseload operation is required when the generator is paralleled with an
infinite bus or utility grid without a Generator Loading Control, Process Control,
Automatic Power Transfer and Load Control, Import/Export Control, or other load
controlling accessory, or when paralleled with incompatible governors (all
Woodward analog electric load-sharing systems are compatible). When running
a single unit on an infinite bus with a Generator Loading Control or Import/ Export
Control, terminal 37 must be activated to connect the Load Matching Circuit to
the load-sharing lines. The load-sharing lines must be wired to the Generator
Loading Control or Import/Export Control. The circuit-breaker auxiliary contact
will then be connected to the Generator Loading Control or Import/Export Control
and not to the 2301E Load Sharing And Speed Control.
This discrete input is used to change the control operation by selecting a second
set of dynamic terms to be used when the input is closed. This command is
normally used when the closed loop path needs two independent sets of
dynamics. The dual dynamics control function is enabled by the Service menu
item ENABLE DYNAMICS 2 W/CB.
The 2301E has a droop tracking feature which allows the control to constantly
monitor the system load. If the unit is in isochronous mode, and the unit is
switched to the droop mode, the unit will maintain the current load level and also
maintain the current engine speed (rpm). Once in the droop mode, if load
changes, then speed / frequency will also change.
Derate KW Load Reference
This input switch or relay contact is used to switch the Rated Load setting from
one value to another value. This feature can be used on applications where two
different gases are used on the engine with different BTU contents. One type of
gas can carry more load than the other type.
50 / 60 Hertz Operation
This input switch or relay contact can be used to switch the Rated Speed setting
from one value to another value. This feature can be used in Rental Package
generators, where generator frequency might change. This switch can only be
operated when the engine is shutdown.
