Description
The 9905/9907 series of the Woodward 2301A controls load sharing and speedof generators driven by diesel or gasoline engines, or steam or gas turbines.These power sources are referred to as "prime movers" throughout this manual.
The control is housed in a sheet-metal chassis and consists of a single printedcircuit board. All potentiometers are accessible from the front of the chassis.
The 2301A provides control in either isochronous or droop mode.
The isochronous mode is used for constant prime mover speed with:
Single-prime-mover operation
Two or more prime movers controlled by Woodward load sharing control systems on an isolated bus
Base loading against an infinite bus with the load controlled by an AutomaticPower Transfer and Load (APTL) Control, an Import/Export Control, a GeneratorLoading Control, a Process Control, or another load-controlling accessory.
The droop mode is used for speed control as a function of load with:
Single-prime-mover operation on an infinite bus or Parallel operation of two or more prime movers.
The following is an example of the typical hardware needed for the 2301Asystem controlling a single prime-mover and generator:
A 2301A electronic control
An external 20 to 40 Vdc power source for low-voltage models; 90 to 150Vdc or 88 to 132 Vac for high-voltage models.
A proportional actuator to position the fuel-metering device, and Current and potential transformers for measuring the load carried by thegenerator.
Applications
The 2301A 9905/9907 series electronic controls have switch-selectable speedranges. Any of these control models can be set to operate within one of thefollowing rated speed ranges:
500 to 1500 Hz
1000 to 3000 Hz
2000 to 6000 Hz
4000 to 12 000 Hz
WARNING—OVERSPEED
The speed range is factory set for 2000 to 6000 Hz. Refer to the inside coverto change speed range and prevent possible overspeed. Using the wrongspeed range could cause an overspeed with resulting damage to equipmentand/or personal injury or death.
CAUTION—DO NOT TURN POTS BEYOND THEIR STOPS
The Rated Speed potentiometer is the only multi-turn pot in this control. Allother pots are single-turn. Take care not to turn these pots beyond their stops.
