针对反馈线性化方法难以同时提高电力系统的功角稳定性和电压调节特性的问题,提出了基于分层设计思想的非线性切换励磁控制方法。首先采用逆系统方法实现了系统的反馈线性化,然后根据Lyapunov函数方法对包含零动态的部分线性化系统设计了切换励磁控制器。在电力系统专用仿真平台上的仿真结果证明了所设计的切换控制器能够有效改善功角稳定性和端电压调节特性。 Aiming at the problem that the feedback linearization method can not improve the power angle stability and the voltage regulation characteristics of the power system at the same time, a nonlinear switching excitation control method based on the layered design idea is proposed. Firstly, the feedback linearization of the system is implemented by the inverse system method. Then the switched excitation controller is designed for the partially linearized system with zero dynamics according to Lyapunov function method. The simulation results on power system simulation platform prove that the designed switching controller can effectively improve the power angle stability and voltage regulation characteristics.
