Research On Optimal Adjustment Of Control System Based On SIS

With the implementing of separating power plant from power network and generation bidding in power market reforming and the constructing of information in power plant, realizing power plant's management and control by establishing SIS(Supervisory Information System)has become an indispensable task of power corporations. How to use historical data of SIS effectively for farther research is attended by many researchers. Aiming at the problem that shortcoming of simple genetic algorithm, a modified real-code hybrid algorithm is proposed and its application in thermal process identification and parameters optimization for PID controller is studied in this paper. Finally, this paper discussed the design idea of PID parameter tuning of control systems in SIS,which establishes solid foundation for theory research to engineering.
