摘　　要：通过对OPC动作引起系统振荡的机理分析加入频率偏差信号结合模糊控制原理实现对OPC动作逻辑的修改,利用免疫算法结合功率偏差信号对控制器的参数进行自适应调整实现控制规则的在线整定,整个控制过程结构简单,稳定性强且易于工程实现。针对2006-07-07贵阳南部电网事故,根据实际系统,用NE-TOMAC程序建立了原动机、调速器和汽轮发电机过速保护及其附加控制的详细模型,仿真结果表明了该控制器的有效性。This paper designs a fuzzy controller through mechanism analysis of system oscillation joining with frequency deviation signal caused by OPC action, using combining immune algorithm with power deviation sig nal to adjust the controller parameters adaptively. The entire controller has simple structure, strong stability and it is easy to be implemented in the engineer. For the incident on the 7th July,2006 in the Guiyang South Grid ,the simulation is conducted by using NETOMAC based on the real network data, testing data of the field measurements, and supplement data of classic values, models of the real prime mover, governor, OPC and load of the China Southern Power Grid. The simulation results show the effectiveness of this controller.
