| Abstract: | Main steam temperature is a very important parameter in power plants,and its control system often adopts the cascade PID structure.The control performance affects the safety and economy of the power plant running significantly.This paper analyzed the performance estimate method of the main steam temperature control system by using the PID-achievable minimum variance as benchmark to define a performance index.The research validity was verified by the practical data of a power plant.The verified results show that the method is effective to analyze the control system. |
