摘　　要：为大规模开发新能源基地,实现跨区能源互补,提高外送能力,新疆电网依托国家电网公司特高压同步电网的构建,在南疆部分区域存在应用特高压交流技术的可能性。通过仿真计算,从电压控制、电压稳定、动态稳定等角度分析西部特高压同步电网故障或周边区域电网内部故障对新疆750 kV电网的影响,从潮流转移、电压支撑能力等方面分析特高压同步电网对疆内直流支撑能力。In order to develop new energy bases on a large scale,realize cross regional energy complementarity,and improve the ability of external transmission,relying on the construction of the State Grid Corporation′s UHV synchronous power grid,Xinjiang Power Grid has the possibility of applying UHV AC technology in some areas of southern Xinjiang.Through simulation calculations,the impact of western UHV synchronous power grid faults or internal faults in the surrounding area power grid on Xinjiang 750 kV power grid was analyzed from the perspectives of voltage control,voltage stability,and dynamic stability.From the aspects of power flow transfer and voltage support capability,the DC support capability of UHV synchronous power grid in Xinjiang was analyzed.

关 键 词：电压控制 电压稳定 动态稳定 电压支撑能力
