Product Detail

WOODWARD 9907-164 505 Digital Governor for Steam Turbines
Description:
The 505 control is packaged in an industrial hardened enclosure designed to be mounted within a system control panel located in a plant control room or next to the turbine. The control’s front panel serves as both a programming station and operator control panel (OCP). 
This user-friendly front panel allows engineers to access and program the unit to the specific plant’s requirements, and plant operators to easily start/stop the turbine and enable/disable any control mode. Password security is used to protect all unit program mode settings. The controller’s 8.4-inch (21 cm) graphical display allows operators to view actual and setpoint values from the same screen, simplifying turbine operation.
Turbine interface input and output wiring access is located on the controller’s lower back panel. Un-pluggable terminal blocks allow for easy system installation, troubleshooting, and replacement.
Designed for steam turbine control, the 505 control includes four PID controllers (Speed, Cascade, Aux-1, Aux-2), multiple start-up routines (manual, semi-auto, automatic, remote control), and multiple protection functions (overspeed, critical speed range, max power, etc.) which can be configured by a user depending on the specific turbine application’s requirements. Users can configure the 505’s different PID controllers, start routines, and protection levels themselves without the need for a special control engineer. Once configured, the 505 performs a configuration check routine to
ensure that the programmer did not make any basic configuration mistakes. 
The 505’s Speed PID can be used to control unit speed/frequency when isolated and unit load when paralleled to an infinite bus (utility). The Speed PID can be programmed to sense unit load via its actuator output signal or a 4–20 mA analog input signal from a generator power sensor. When programmed to sense and control generator load via a analog input true unit load is sensed and controlled. By using the generator load signal to control from, any turbine inlet or exhaust pressure variation is sensed and compensated for, thus providing true load control.
A combination of the Speed PID and its setpoint limits allow this PID to limit unit load. When used as a unit load limiter, it is recommended that the 505 be configured to sense and control only true generator load. If applying the 505 system to a soft grid (utility frequency varies greatly) it is recommended that unit load limiting be performed by the Auxiliary PID not the Speed PID.
