Abstract:
In this paper,a full range digital control system for the steam generator water level is designed by a control scheme of single element control and three-element cascade feed-forward control,and the method to use the software module configuration is proposed to realize the water level control strategy.This control strategy is then applied in the operation of the nuclear power simulation machine.The simulation result curves indicate that the steam generator water level maintains constant at the stable operation condition,and when the load changes,the water level changes but finally maintains the constant.
