江西东部电网与主网电磁环网解环运行分析

随着江西电网不断扩大,接入500 kV电源点不断增多,500 kV鄂赣第三回联络线建成投产网间受电大幅提高,江西电网500 kV系统输送潮流增大,系统短路容量也逐步提高,高低压电磁环网的问题日益突出。本文根据江西电网解环方案,结合实际情况对江西东部电网与江西主网解环运行进行分析。

Analysis on Electromagnetic Uncoupling Loop of Jiangxi Eastern Part Power Network and Main Grid

With the development of Jiangxi power grid,problems of electromagnetic loop network has emerged,for instance,power supply points increased,acceptance electricity enhanced because of operation of 500 kV Hubei-Jiangxi the third circuit,transmission flow of 500 kV increased,short-circuit capacity also raised.Electromagnetic uncoupling loop of Jiangxi eastern part power network and main grid was analyzed in the paper.
