WOODWARD 9907-162 505 Digital Governor for Steam Turbines
Description:
The 505 controller is designed to operate industrial steam turbines of all sizes and applications. This steam turbine controller includes specifically designed algorithms and logic to start, stop, control, and protect industrial steam turbines or turbo-expanders, driving generators, compressors, pumps, or industrial fans.
The 505 control’s unique PID structure makes it ideal for applications where it is required to control steam plant parameters like turbine speed, turbine load, turbine inlet header pressure, exhaust header pressure, or tie-line power. The control’s special PID-to-PID logic allows stable control during normal turbine operation and bumpless control mode transfers during plant upsets, minimizing process over- or undershoot conditions. The 505 controller senses turbine speed via passive or active speed probes and controls the steam turbine through one or two (split-range) actuators connected to the turbine inlet steam valves.
The 505 controller also includes the following turbine protection functions to ensure that the turbine or its driven load (compressor, pump, generator) is not operated outside of its designed limits:
3 Critical speed avoidance bands
Overspeed anticipation and shutdown protection
Configurable under- or over-pressure shutdown logic
Minimum and maximum speed and load settings
Ethernet and serial communications allow users to easily connect the 505 into the plant or process control system. All controller inputs, outputs, and statuses can be monitored, and all start/stop or enable/disable commands can be given through industry standard Modbus® * TCP or OPC protocols. The 505 uses SNTP (synchronized network time protocol) over
Ethernet to allow users to synchronize the 505’s real-time clock to the plant distributed control system.
