摘　　要：随着特高压输电工程和皖北大电源集中投产,短路电流成为困扰安徽电网安全稳定运行的重要因素。在华东电网"十二五"规划网架下,对安徽电网2014年、2015年短路电流超标厂站进行分析,并从调整运行方式、改变网架结构和串联电抗器3方面提出短路电流限制措施。通过BPA仿真计算,从短路电流限制效果、静态安全分析及供电可靠性3方面考虑,得到最佳方案。With the commissioning of UHV transmission project and large-sized power plants in northern Anhui, the short-circuit current has become a major risk factor constrain- ing the safe and stable operation of Anhui power grid. In this paper, firstly, the short-circuit current of Anhui power grid under the Twelfth Five-Year Guideline network of East China power grid is analyzed, and limiting measures are proposed through adjusting the operation mode, changing the network configuration and series reactors. Through the BPA simulation, the optimal scheme is obtained from three aspects of short circuit current limiting effect, static security analysis and power supply reliability.
