# 基于模糊自整定PID的广域电力系统稳定器设计Design of Wide Area Power System Stabilizer Based on Fuzzy Adaptive PID

Abstract: The design of wide area power system stabilizer is studied in this paper. Firstly, the principle and characteristics of PID control are analyzed, and the fuzzy self-tuning PID controller and its control method based on the characteristics of fuzzy control are presented in order to adapt to the randomness of power network. Based on the traditional PSS, the design flow of the wide area power system stabilizer is analyzed, and the fuzzy control language variables and membership functions are determined, and the fuzzy rules are formulated to control the control measures. Finally, the performance of controller designed is tested by the simulation of Two Area and Four Machine Grid System and a region of East China. Simulation results show that the controller can effectively adapt to the randomness of the power grid, improve the damping of the power system and improve the stability of the interconnected power system.
