Based on the simulation software Matlab / Simulink,the nuclear power plant power control system modeling was processed. In order to reduce control rod travel and improve the control quality in the dynamic process,the variable parameter PID control algorithm was proposed,and the reactor power control system was optimized through adjusting the parameters of the controller adaptively under different power levels. With the connection of circuit device and nuclear thermal hydraulic model,the control effect of algorithm was simulated. The results show that the method can be used to track both in the reactor of different power levels adjustment with well performance and can reduce the control rod travel and wear,which has the reference value to improve the reactor power regulating system.
