现阶段配电网的无功补偿的分析及改进

Na Analysis and Improvement of Reactive Power Compensationin Distribution Network at Present

文章简要介绍无功补偿的原理及意义,着重讨论无功补偿在现阶段供电企业中的实际管理现状,分析其存在的问题,主要提出必须改进公用变压器0.4 kV母线集中补偿的形式,将公用低压配电网的无功补偿设置到用户终端进行分散补偿,以避免无功电流在低压配电网上引起损耗,同时提出其他管理和政策上的改进建议。

Briefl y introducing the principle and signifi cance of reactive power compensation,this paper focuses on the current situation of reactive power compensation in the practical management of power supply enterprises.In consideration of some existing problems,in this paper we propose to alter and improve the form of centralized compensation of 0.4 kV bus of public transformer—the reactive power compensation of public low-voltage distribution network should be set to the terminal users for decentralized compensation,so as to avoid the loss caused by reactive power current in the low-voltage distribution network.Besides,this article puts forward other improvement proposals on management and relative policy.
