| 摘 要： | 本文将模糊集理论用于对电力系统稳定水平的评估中,在电力系统处于不同状态时,根据评估的结果选择非线性最优控制或者PID PSS控制,即采用与此状态相适应的励磁控制规律。仿真结果表明:本文提出的混合励磁控制策略能够将PID PSS励磁控制和非线性最优励磁控制各自的优点相结合,从而使励磁控制在实现励磁基本控制功能的同时,具有更强的提高电力系统功角稳定的能力。

| Abstract: | Fuzzy set theory is applied for the evaluation of power system stable level.By considering the evaluation results,the nonlinear optimal excitation control or PID PSS excitation control is chosen,namely,when the stability situation of power system is changed,the excitation control tactics which is suitable for the present power system will be chosen.The simulation results indicate that the compound excitation control tactics is able to combine the advantages of PID PSS excitation control with the nonlinear optimal excitation control,which makes the excitation control able to advance the stability of power system as well as the basic control function successfully. |
