摘　　要：通过对电气距离的分析,可得到无功源的合理配置方案。对比分析两种电气距离分区方法,利用电气距离的相关联性找出电力系统中耦合性最好的节点,并对该节点进行相应的无功补偿设置,以得到全系统最优补偿结果。经过仿真分析比较,两种分区方法都能实现无功源的分区配置及提高系统电压稳定性效果,但各自侧重补偿点及电压提升效果有所不同。Through the analysis of the electric distance,we can get a reasonable allocation of reactive power source.In this article,comparative analysis of two kinds of eletric distance partition methods,we can use the electric distance coupling power system of phase correlation to find the best node and set the corresponding reactive power compensation to get the optimal compensation results in the power system.After the simulation analysis and comparison,the two methods can realize the reaction power source partition configuration and improve the effect of voltage stability.But their emphasis on compensation point and the effect of voltage stability are different.
