摘　　要：控制好电压和无功并且使其在合格范围内运行具有重要的意义.基于传统九分区的电压无功综合控制存在投切震荡现象,而变电站电压无功模糊控制可以避免这些问题.依据变电站电压无功模糊控制策略设计一个变电站电压无功模糊控制器,并对该模糊控制器进行MATLAB仿真,通过数据分析可以证明设计的模糊控制器能够减少变压器分接头和并联电容器的调节次数,增加变电站设备的使用寿命.Since the voltage and reactive power are two key factors of the power quality evaluation, how to control the voltage and reactive power and making it within an acceptable range operation are of great signifi- cance. Voltage and reactive power control based on the traditional nine partitions exists oscillation question in switch operation, however, the fuzzy control method that the substation voltage and reactive power control can avoid these problems. A substation voltage and reactive power fuzzy controller is proposed in the paper accord- ing to fuzzy control strategy, and the MATLAB simulation are made on the fuzzy controller, the analysis results prove that the fuzzy controller designed in this paper can reduce the regulation numbers of transformer taps and shunt capacitors, meanwhile increase the service life of the substation equipment.
