Application of a nonlinear system identification method to thermal power plants

Yukihiro Toyoda, Kiyoshi Wada · Electrical Engineering in Japan · 2001

AbstractElectric power companies pay attention to the load following capability and economical operation of a thermal power plant with once‐through boilers. However, conventional PID controllers embedded in DCSs cannot always provide the optimum solution for such subjects. To cope with these problems, we discuss a model‐based advanced control system. Prior to study of the advanced control system, we develop a nonlinear system identification method based on the exogeneous variable‐dependent ARX model considering the characteristics of power plant dynamics. We verify its effectiveness through simulation tests by using measurement data collected in field tests and simulation tests with SIMULINK‐based boiler‐turbine dynamic models. © 2001 Scripta Technica, Electr Eng Jpn, 137(2): 26–35, 2001
