【摘要】 介绍了两种变电站电压无功控制策略,并对采用模糊无功边界"九区图"和"五区图"控制策略进行模糊控制的实例作了仿真对比分析,可以看出:这两种控制策略均能满足变电站电压无功控制目标,但基于五区图的控制策略能使变压器的动作次数明显减少。更多还原

【Abstract】 The article describes two strategy on voltage and reactive power control for Sub-station,a simulation comparison is does through using control strategy of "nine-zone" theory with fuzzy Var boundary and "five-zone" theory,find out: the two control strategy all can satisfy voltage and reactive power control target for Sub-station,but the control strategy on "five-zone" can effectively reduce the action times of transformer.更多还原
