Basic details :9907-167 505E figures Governor Woodward

The 505E controller is designed to operate single pump/feed steam turbines of various sizes and applications. The turbine controller includes specially designed algorithms and logic to start, stop, control and protect a single extraction and or entry into the turbine or turbine expander. Drive generators, compressors, pumps or industrial fans. The 505E controller's unique PlD structure makes it ideal for applications where steam plant parameters need to be controlled, such as turbine seeds. Next to tudine. Turbine pressure. The control's special PID-o-P1D logic allows for stable control during normal turbine operation and no bump-control mode transfer during plant disturbances, minimizing process overshoot or undershoot conditions. The 505E controller senses the turbine seed through passive or active speed probes and controls the turbine through HP and lp actuators connected to the turbine steam valve

The 505E controller senses the extraction and entry pressure via a 4-2 mA sensor and uses piD via the ratio meter function to precisely control the extraction and/or entry head pressure while protecting the turbine from operating outside its designed operating range. The controller uses the OEM steam diagram for a specific turbine to calculate its valve-to-valve decoupling algorithm and turbine operation and protection limits.

Woodward 9907-167 505E Digital Governor is carefully designed to operate single extraction and/or entry steam turbines of different sizes and applications. It combines specialized algorithms and logic customized to fully control and protect these turbines, whether driving generators, compressors, pumps, or industrial fans, and the 505E control is equipped to manage every aspect of their operation.

Advanced control algorithm of steam turbine operation

One of the outstanding features of the 505E controller is its unique PID construction, which makes it highly suitable for applications requiring precise control of steam plant parameters. From turbine speed and load to inlet and exhaust pressure, extracting inlet head pressure and line power, the 505E control excels at maintaining optimal operation.

Smooth and stable control transitions The 505E controller's dedicated PID-to-PID logic ensures stability during conventional turbine operation and seamless transition of control modes during unexpected plant outages. This capability minimizes process deviations and contributes to a smoother and more efficient overall operation.
