The 505E controller is designed for single extraction and/or inlet steam turbines of various sizes and applications, and can start, stop, control, and protect single extraction and/or inlet steam turbines or turbine expanders that drive generators, compressors, pumps, or industrial fans. Its unique PID structure is suitable for controlling steam equipment parameters, such as turbine speed, load, inlet pressure, exhaust manifold pressure, extraction or inlet manifold pressure, or tie line power. The controller achieves stable control during normal operation of the steam turbine through special PID to PID logic, and switches to disturbance free control mode in case of equipment abnormalities, reducing process overshoot or undertuning.
