摘　　要：为了研究同塔双回架空线-电缆混合输电方式下的合闸暂态过电压,选取某供电局220 kV罗文甲线为研究对象,利用ATP-EMTP电磁暂态计算程序建立了同塔双回架空线-电缆混合输电方式暂态模型,对合闸暂态过电压进行了研究,分析了旁边线路带电与检修状态、合闸不同期对合闸暂态过电压的影响;同时,对合闸暂态过电压进行了简单的容升效应分析。For researching the close transient overvoltage of headline-cable comprehensive transmission with double circuit transmission lines on the same tower, select a power supply bureau 220 kV Luowenjia line as the research object, using ATP-EMTP electromagnetic transient program established a headline-cable comprehensive transmission transient model with double circuit transmission lines on the same tower of closing transient overvoltage is studied, analyzed the influenee of side line electrification and maintenance state, different closing period to closing transient overvoltage. At the same time, simple analysis of transient overvoltage in closing on lift effect.
