摘要
分析了变电站电压无功综合控制中九区图控制策略的主要缺陷,给出了一个基于模糊控制理论的变电站电压无功综合控制系统的设计算例,并采用MATLAB对所设计的考虑负荷变化的电压无功模糊控制以及九区图控制策略进行了仿真分析,得出模糊控制的效果要优于传统的九区图法,能有效地减少分接头的调节次数,改善变电站的功率因数。
The main defects of 9-area control strategy of the synt he tic and automation control of voltage and reactive power in substation are analy zed. A design example of VQC based on FLC is given out, and MATLAB is used to simulate and analyze it. The result shows that effect of fuzzy control is better than 9-area method, the adjusting times of transformer taps is reduced and the power factor of substation is improved effectively.
