摘要
随着新疆电网规模的快速发展、大电源的接入、与西北电网联网运行,新疆电网在满足了不断增长的电力需求的同时,短路电流的水平也日益增大,需要高度专注。结合新疆电网的发展规划,利用PSASP程序进行新疆电网短路电流计算,通过对新疆电网近几年短路电流水平的分析,短路电流值主要分布区间和短路电流限制措施的分析,提出新疆电网短路电流存在的问题以及限制短路电流的方法,为电网断路器设备选型、电网运行方式优化、打开电磁环网,电网规划提供理论依据和借鉴。
With the rapid development of Xinjiang power grid,the augmentation of its big capacity and the interconnection with Northwest power grid,Xinjiang power grid has satisfied the unceasing power demand,meanwhile,it needs a high attention to the increasing short-circuit current.According to the development plan of Xinjiang power grid,the short-circuit current of Xinjiang power grid is calculated with PSASP program.Through the analysis of short-circuit current in recent years,as well as the analysis of the major distribution areas of short-circuit current and its restrictive measures,the existing problems of short-circuit current in Xinjiang power grid and the methods to limit the short-circuit current are proposed,which provides the theoretical foundation and reference for the type selection of circuit-breaker,the optimization of operating mode,the opening of electromagnetic ring and the planning of power grid.
