500kV抽能并联电抗器抽能绕组改造方案研究

Study on Transformation Scheme of Energy Extraction Wingding of 500kV Energy Extraction Shunt Reactor

本文作者分析了500kV并联电抗器烧损的原因,针对抽能电源系统退运后抽能绕组的改造,提出了5种方案建议,并对每种方案的优缺点进行了技术经济分析比较,供装有同类型抽能并联电抗器的变电站参考。

In this paper,the author analyzes the cause of burning loss of 50okV shunt reactor,puts forward five proposals for the transformation of the pumping winding after the withdrawal of the pumping power system,and makes a technical and economic analysis and comparison of the advantages and disadvantages of each scheme for the reference of substations equipped with the same type of pumping shunt reactor.
