Woodward 9905-966 Digital Governor Controller Module

Product Brief Description

Woodward 9905-966 is a high-performance digital governor controller module designed for turbine and engine speed control. It precisely regulates speed, load and excitation for gas turbines, steam turbines and reciprocating engines. Built for rugged power generation environments, it supports flexible configuration for island mode, grid parallel operation and protective interlock functions.

Product Functions

• High-precision speed sensing and closed-loop speed regulation for prime movers
• Load control and load sharing for multiple generator sets in parallel operation
• Grid synchronization check, auto-sync and breaker close control
• Overspeed protection, reverse power and abnormal condition alarm logic
• Analog and discrete I/O for actuator drive, sensor feedback and interlock signals
• Onboard event logging and fault recording for post-trip troubleshooting
• Support communication for SCADA, HMI and remote monitoring systems
• Configurable parameters via software for different engine and turbine types

Application Scenarios

• Gas turbine and steam turbine generator control systems
• Diesel and gas engine generator sets for standby and prime power
• Combined cycle power plants and industrial captive power stations
• Oil & gas offshore platforms, compressor and pump drive units
• Mining, chemical and metallurgy self-generation power systems
• Power plant overhaul, spare replacement and control system retrofits
