摘　　要：随着宁夏电网逐步形成高电压、大电源、交直流混联的送端电网,短路电流越限问题已成为限制宁夏电网发展的主要问题之一。采用电网分区供电、网架结构优化调整、限流电抗器等高电压等级短路电流限制措施,以网架坚强、结构合理、安全可靠为目标,提出了2030年宁夏电网750kV目标主网架规划方案,通过网架结构、潮流和短路、实施难度、方案投资等多方面比较分析,明确了宁夏电网750kV目标主网架推荐方案和330kV/220kV电网分区方案,为“十四五”和“十五五”期间宁夏电网的规划、建设指明了方向。As Ningxia Power Grid gradually forms a high voltage, large power, AC DC hybrid transmission side power grid, the problem of short circuit current over limit has become one of the major problems limiting the development of Ningxia Power Grid. With the goal of strong grid structure, reasonable structure, safety and reliability, adopting the high voltage short circuit current limiting measures such as power grid partition power supply, grid structure optimization adjustment, series reactors, etc., the 750 kV target main grid plan of Ningxia Power Grid is proposed. Through the comparative analysis of grid structure, power flow and short circuit, implementation difficulty, and program investment, the 750 kV main grid recommendation scheme of Ningxia Power Grid and the 330 kV/220 kV grid zoning scheme are clarified. It pointed out the direction for the planning and construction of Ningxia Power Grid during the“14th Five Year Plan”and“15th Five Year Plan”period.
