摘要/Abstract

摘要： 因电容器的补偿容量和其接入点的电压水平有着密切关系,所以在潮流分析的基础上,提出一种考虑电容器电压特性,利用节点无功裕度排序法找到系统无功源最佳配置点进行无功补偿的方法。结合某地区配电系统的实际应用,采用该方法对其无功补偿情况进行了分析,仿真结果与实际测试验证了该方法的有效性。

Abstract: The actual compensation of capacitor capacity has a very close relationship with the voltage level of the access points. Therefore, based on the power flow analysis, a compensation method, which considers the capacitor’s voltage characteristics, is proposed to use the sorting method for node reactive power margins to find the best configuration for reactive power source access. The method is applied to the distribution system of a region for analyzing the reactive compensation and the results of simulation and actual testing proves the method’s high efficiency.

Key words: power system, distribution system, reactive power compensation, capacitor, voltage-dependent characteristics, node, reactive power margin, compensation method, sorting method
