The Research Of A New Coordinated Control Method

With the wide application of AGC,The electric network is required that the boiler-turbine-generator set react to the load demand quickly, and make sure that it can perform safely, stably and economically at the same time. To improve the responding time of the load demand of the electric network, this paper combine advantage of boiler following respond fast , turbine following pressure change steady together and improves turbine following control method, join an intellectual control link, make it can not only keep the advantage with steady pressure but also respond load fast. Through simulation, it proves there are better control results which this method and the conventional PID control and compared. In order to improve the performance of the control system further, this text improves the boiler PID controller, have designed the fuzzy PID controller of boiler. Through simulation, it control method and conventional PID and before improved coordinating control method are compared, there are better control results.
