WOODWARD 9907-1183 505E Series Steam Turbine Digital Speed Control Controller
9907-1183 belongs to the Woodward 505E series steam turbine digital speed controller, which integrates an operation panel, display unit, and control logic. It uses a 32-bit microprocessor and is specifically developed for industrial steam turbines, turbine generators, and turbine expanders. It supports control of extraction and replenishment steam turbines. 9907-1183 is widely used in cogeneration, power plants, and petrochemical process drive units. It can operate independently or be connected to the DCS distributed control system to achieve closed-loop regulation of turbine speed, load, and pressure. It is the core control unit of the turbine speed control system.
Product function
- Speed closed-loop regulation: Receive speed probe signals, control the electro-hydraulic actuator, achieve stable control of turbine speed, and complete speed increase, constant speed, and grid connected operation.
- Load and extraction pressure control: Supports PID closed-loop control of unit load regulation, inlet pressure, and extraction/replenishment pressure, suitable for cogeneration units, and balances power generation and steam supply conditions.
- Unit protection logic: Built in overspeed protection, zero speed detection, shutdown interlock, triggering turbine shutdown protection in case of abnormal conditions to ensure equipment safety.
- Local operation and human-computer interaction: panel buttons and display screen enable parameter modification, status viewing, fault code reading, and on-site start stop operation.
- External communication interaction: Upload speed, load, alarm and other data to DCS through Modbus communication, and receive remote DCS commands to achieve remote control
- External communication interaction: Upload speed, load, alarm and other data to DCS through Modbus communication, and receive remote DCS commands to achieve remote control
