电力系统智能PI稳定器

Power System Intelligent PI Stabilizer

本文提出一种电力系统智能PI稳定器的设计方法,它由两层决策系统、识别环节及智能PI控制环节组成。控制规律模仿人的经验、推理及决策,能随电力系统运行方式及工况的变化,保持向系统提供有效的控制,提高系统的稳定性。文中给出了这种智能PI稳定器的设计实例及非线性仿真结果。

This paper presents a power system intelligent PI stabilizer, which consists of two -layer decision unit, distinguishing unit and intelligent PI control unit. The control rules of the proposed stabilizer are a direct imitation of experience, inference and decision on human being. With the viaration of operating conditions and system configurations of a power system, this intelligent PI stabilizer can keep supplying an effective control to improve the stability of the power system. The design examples both of single - machine and multimachine power system as well as nonlinear simulations are given in the paper.
