摘要
在Simulink软件平台上,以单机-无穷大电力系统为模型,在系统发生阶跃干扰和短路故障两种情况下,分别采用最优控制和PID+PSS控制两种励磁控制方法进行仿真比较研究,仿真结果表明两种励磁控制方法均能提高电力系统暂态稳定性,但最优励磁控制效果更佳.
The single infinite power system is used as a model;two excitation control methods of optimal control and PID＋PSS control are simulated and compared in step disturbance and short-circuit fault on Simulink software platform.The simulation results show that two excitation control methods can improve transient stability of power system,but the optimal excitation control has better control effect.
