配变三相不平衡解决方案及控制策略
摘要
在三相四线制低压配电网中
常出现三相电流不平衡问题
这主要是由于用户接电三相负荷不均等、用户用电随机性引起的。三相电流不平衡会增加低压供电线路的损耗
引起低电压问题
严重时甚至会损坏供用电设备。本文主要研究了低压配电网的三相不平衡问题
针对配网线路存在的不同问题提出了多种解决方案和控制策略
为治理三相不平衡问题提供了参考建议。
Abstract
The issue of three-phase current unbalance is often occurred in the three-phase four-wire low voltage distribution networks mainly due to unequal three-phase load and random power application by the user. Unbalanced three-phase current can increase loss of low voltage power supply line
lead to low voltage issue and
if serious
even damage the power supply equipment. In this paper
the issue of threephase unbalance in the low voltage distribution network is mainly studied and multiple solutions and control strategy existing in the distribution line is proposed
which provides reference suggestion for the control of three-phase unbalance.
