摘　　要：介绍了宁夏电网短路电流现状和发展,以及目前解决短路电流过大方面的主要对策。分析了宁夏电网短路电流的突出点,重点分析了限制银川东330 kV母线、黄河和银川东750 kV母线短路电流的措施以及限制750 kV变电站中压侧母线单相短路电流的措施,并得出了初步结论。可为今后宁夏电网规划及后续的电网建设项目可行性研究工作提供参考。This paper introduced the present situation and development of the short-circuit current in Ningxia power grid, as well as the main measures to limit short-circuit current. Detailed analyses of the measures to limit the short-circuit current of 750 kV substations, both HV and MV sides, were made, and preliminary conclusions were drawn. The results can present reference for Ningxia power grid planning and feasibility studies of grid construction projects.
