湖北电网2007年短路电流水平及限制措施

Short-circuit current level and it's limited measures for hubei power grid in 2007

随着湖北电网规模的扩大、容量的上升,如何有效控制系统内不断上升的短路电流水平已成为摆在网内电力科技工作者面前的重要研究课题.结合湖北电网的发展规划,根据基于PSASP程序的2007年湖北电网短路电流计算结果,对湖北电网结构、短路电流增长原因及其带来的问题进行分析,提出限制短路电流的主要技术措施.

With the expanding of the Hubei power grid and the augmentation of its capacity, an ettective measure to limit the unceasingly growing short - circuit current of the power grid becomes an important research topic. According to the Hubei power grid＇s development plan, based on the short-circuit current calculated with PSASP program, the structure for the power grid, the reasons and the impacts for the short-circuit current＇s growth are analyzed in the paper. And some effective measures to limit the shortcircuit current are also proposed.
