【Abstract】 Shang An power plant is a sub-contrd loop of Network-90 system. May new control methods and strategies are used to control the whole load range of drumlevel. The circuit balancing.the control transferring from single -impulse to three-impulse and the controller "Look up" proble in case of load rejection are discussed in this paper. The paper also introduces some improvements and problems not solved during commissioning.更多还原
