Abstract: Reactor power control system is an important instrument and control system. It plays an significant role in the normal operation of the nuclear power plant (NPP). In order to guarantee the good control performance of control system during normal operation of NPP and to decrease the on-site commissioning time, it is necessary to optimize the control parameters through simulation study on the control system in the design stage.Based on the analysis of the reactor power control system function of the third generation nuclear power Hua-long Pressurized Reactor (HPR) 1000, the control system structure is proposed and the interrelated factors of the control channel are explained. Through the process of system modeling and simulation, sensitivity analysis of control parameters is carried out using the nuclear power plant digital simulation tools.According to the static and dynamic response characteristics of the system with different parameters, a set of optimal control parameters are finally determined. The obtained control parameters are now used in the design of reactor power control system for the first reactor of HPR1000 in China, which can guide the on-site commissioning and operation of the nuclear power plant.
