Woodward 2301A
Product overview
Woodward 2301A load distribution and speed controller is specially designed for electronic power generation systems that need multi-unit load distribution. The controller can be used with diesel engines, gas engines, gasoline engines, steam turbines, or gas turbines, and is suitable for industrial scenes with strict reliability requirements.
The controller adopts a metal plate cabinet structure, with a single printed circuit board inside. All potentiometers can be operated directly from the front panel of the cabinet, which is convenient for on-site debugging and maintenance.
control model
2301A provides two core control modes: Isochronous mode and Droop mode.
Constant speed mode is used to maintain the constant speed of the prime mover, which is suitable for the following scenarios: single machine operation; Two or more prime movers are cooperatively controlled by the Woodward load distribution system on the isolated bus; and cooperation with accessories such as automatic power transfer and load control (APTL), import and export control, generator load control, or process control to carry out basic load operation on the infinite bus.
The droop mode is used to control the speed according to the load function, which is suitable for single machine running on the infinite bus or parallel running of more than two prime movers.
Speed range and safety warning
The 2301A series controller has a speed range with optional switches, and all models can be set to run in any of the following rated ranges: 500-1500 Hz, 1000-3000 Hz, 2000-6000 Hz and 4000-12000 Hz.
Overspeed warning: the speed range is set at 2000-6000 Hz. Please refer to the instructions on the inside page of the manual before changing the speed range. Using the wrong speed range may lead to overspeed, which may cause equipment damage and/or personal injury or even death.
Attention to the operation of potentiometers: The Rated Speed potentiometer is the only multi-turn potentiometer in the controller, and the others are single-turn potentiometers. Avoid turning the potentiometer past its limit when operating.
Core characteristics
2301A has the following functional characteristics to meet the requirements of control accuracy and reliability of the power generation system:
Automatic start-up fuel limit: limits the maximum fuel position during start-up to reduce pollution and engine wear.
Built-in load sensor: most models can output a 0–200ma control signal, which is compatible with Woodward EG, EGB, PB, TM, and 2301 actuators.
Speed/load setting: No actuator position feedback signal is required.
Compatibility: It can be used with Woodward SPM-A synchronizer, automatic generator load control, process input/output control, and automatic power transfer and load control.
Environmental protection: The built-in protection device can resist electromagnetic interference/high frequency harmonic interference (EMI/RFI), moisture, dust, and vibration.
Wide temperature operation: working temperature range -40 to +85 °C.
Typical hardware configuration
Taking the 2301A system for controlling a single prime Mover and generator as an example, the typical hardware includes: a 2301A electronic controller; Low-voltage models need an external 20–40 VDC power supply, and high-voltage models need a 90–150 VDC or 88–132 VAC power supply; A proportional actuator for positioning the fuel metering device; And a current transformer and a voltage transformer for measuring the load of the generator.
Reliability and compliance
2301A controller is designed for harsh environments and has high reliability. The low-voltage model meets the requirements of the EU directive. Woodward, as a leader in the field of prime mover control, provides a global service and technical support network for this product.
