WOODWARD 2301D-ST Digital Load Sharing & Speed Controller
Product Brief Description
The Woodward 2301D-ST is a microprocessor-based digital speed and load sharing controller designed for prime mover control. It delivers high-precision speed regulation, generator load distribution and protection functions, widely used for turbines and reciprocating engine generator sets. Configured via RS232 interface with Watch Window software, it supports flexible parameter setup and real-time equipment diagnostics.
Product Features & Functions
- Precise speed governing and frequency stabilization under variable load conditions
- Automatic load sharing between parallel generator units, equal or proportional load distribution
- Critical speed avoidance protection to skip dangerous rotating speed range automatically
- Remote speed setpoint adjustment via analog input; Modbus RTU communication supported
- Built-in fault detection, self-test and diagnostic functions for quick troubleshooting
- Soft load transfer, torque limiting and automatic idle-to-rated switching
- Supports semi-automatic and automatic startup sequences for prime movers
Application Scenarios
- Gas turbine, steam turbine generator control
- Diesel and gas engine genset parallel operation systems
- On-site power plants, offshore platform power generation
- Industrial backup power and island-mode power supply systems
- Oil & gas industry prime mover speed regulation
FAQ
Q: What software is used to configure 2301D-ST?
A: It uses Woodward Watch Window software. Connection is made through RS232 serial port for parameter upload, download and tuning.
Q: Can 2301D-ST work for grid-connected generators?
A: Yes. It supports parallel gensets for both grid tie and island operation with load sharing capability.
Q: Is this controller a direct replacement for older 2301A?
A: It is designed as functional replacement, but wiring and parameter configuration need rechecking before commissioning.
Q: What communication protocol does it support?
A: It supports Modbus RTU over RS232 for remote monitoring and control commands.
Q: Can it detect overspeed faults?
A: Yes. It includes overspeed monitoring and related protection logic for prime mover safety.
