English Description：
A linear model is built in Simulink to analyze the low-frequency oscillation of power system, and the particle swarm optimization algorithm is used to optimize the design of power system stabilizer. The results show that the power system stability after particle swarm optimization can effectively suppress the low-frequency oscillation of power system.
