Asymptotic stability analysis on generalized intelligent coordinated control system of 600MW unit and engineering application

For overall interests of the entire power system stability, generator units should have faster and more flexible load response characteristics. Due to complexity of dynamic characteristics of controlled object in thermal control field and new problems are caused by large-capacity power generation equipments updated, many difficulties brings out for control system´s design and application. According to concepts and definitions of linear system theory, fussing multiple thinking modes of intelligent control, a generalized intelligent control system was designed and described by state space method in this paper. To explore sufficient condition of asymptotic stability by mathematical analysis, take overall asymptotic stability of control system as the premise, the approaches are given which improved the system rapidity in theory. Engineering practice verify the application effect. The system has opening designing manner that can accept and lodge novel technique method and control thinking of modern control field.
