最小误差控制方法及其在电力系统中的应用

MINIMUM ERROR CONTROL METHOD AND ITS APPLICATION TO POWER SYSTEM

本文在研究Kosut提出的最小误差激励控制方法的基础上,提出了一个新的次最优控制方法——最小误差法。这个方法克服了原方法不能保证闭环系统稳定性的缺点,且更能体现“误差最小这个目标。将本文方法应用于多机电力系统励磁分散控制中,取得了令人满意的结果。

Based on the minimum error excitation control method given by Koust, this paper presents a new suboptimal control method, minimum error method. The method overcomes the shortcoming of the original method which cannot insure the stability of closed loop system. Besides, this method can reach the object of minimum error to the largest extent. The method has been applied to the decentralized excitation control of a multimachine power system, the results are satisfactory.
