电力系统无功补偿点的确定及其补偿方法

Confirming of Reactive Power Compensation Node of System and Compensation Method

基于对临界电压和临界功率在静态电压稳定极限作用的分析,本文讨论简单交流电路的电压电流特性,提出了确定电力系统无功补偿点的方法。讨论了静止无功补偿器(SVC)的作用,指出在电压临界崩溃点采用SVC装置用作无功补偿有利于系统电压稳定的观点。5节点算例表明,补偿效果比较显著。

Based on analyzing of the purpose of the static voltage stability limitation of critical voltage and critical power, the voltage and current characteristics of simple alternative circuit are discussed, and the way of confirming var compensation node of electric power system is indicated. The impact of static var compensators （SVC） is discussed, the viewpoint that putting the node of voltage critical collapse in SVC is applied to var compensation is beneficial to voltage stability of electric system. By 5 nodes algorithm case, the result of compensation is clear.
