配电网无功补偿对电压和线损的影响

Analysis on Effect of Reactive Series,Parallel Power Compensation on Voltage and Line Loss in Power Distribution Network

无功补偿设备是配电网系统的重要组成部分,通过投入电容器进行无功补偿是配电网改善电压质量的有效手段,但不同的补偿方式其经济性是不相同的。串、并联两种无功补偿方式在改善电压质量及降低线损率方面各有优缺点。通过对配电网并联补偿和串联补偿两种方式建立等值模型并进行理论计算和仿真分析,深入探讨其对电压和线损的影响并作综合比较。

Reactive power compensation devices of distribution network are important components of the system and it is an effective way to improve voltage quality through bringing capacitances into service.However, the economical efficiencies of different ways of reactive compensation are not the same.The two kinds of reactive power compensation what are series and parallel both have advan-tages and disadvantages in improving the voltage quality and reduce the loss rate.This article shunt compensation and series com-pensation to build models and theoretical calculations and simulation analysis, the depth of its distribution network voltage and line loss based on the distribution network.
