四川电网2010年短路电流水平分析及限制措施研究

四川电网处于高速发展的时期，电源容量及网架结构将明显加强，在满足不断增长的电力需求的同时，短路电流水平的也日益增大，部分变电站的短路电流水平已经接近或超过其开关现有遮断容量。结合四川电网的发展规划，利用PSASP程序进行2010年四川电网短路电流计算，根据计算结果提出降低短路电流的主要技术措施，并对其有效性进行分析和评估。

Short-circuit Current Analysis and Limiting Measure Research of Sichuan Power Grid in 2010

With the enhancement of capacity and structure for Sichuan power grid,the short-circuit current is increasing by year.Short-circuit current of several substations have approached or even exceeded their interrupting capacity.According to the development plan of Sichuan power grid and based on the short-circuit current calculated with PSASP program,some effective measures to limit the short-circuit current are proposed,and its feasibility and validity is also analyzed and evaluated.
