摘　　要：分析了变电站电压无功控制的原理,对现有的几种VQC控制策略进行了比较,指出了其中的踊些不足,论述了变电站电压无功调节在控制策略和闭锁报警方面应该注意的问题,最后提出了一种改进的电压无功调节方案。A voltage and reactive power control unit has been widely applied in substation, but there are still some problems. This paper analyzes the principle of the voltage and reactive power control. By comparison with the existing methods, some of their advantages and deficiencies are also pointed out. The essential about control strategies and blocking which are worth being improved are described. At last, a new method about voltage and reactive power control is presented.
