Finally,based on a 2-area 4-machine power system,dynamic simulations are carried out to make a comparison between the effects of AVR+ PSS excitation system and the two nonlinear robust controllers in improving transient stability of the system.

• 最后采用2区4机系统进行了动态仿真,以比较这2种鲁棒控制器以及自动电压调节器+电力系统稳定器(AVR+PSS)励磁系统在提高电力系统暂态稳定性方面的控制功效。
