【摘要】 针对500kV郓城-泰山紧凑型(部分同塔双回)输电工程设计,对该线路操作过电压水平及绝缘配合进行较详尽的研究,分析了紧凑型线路合闸操作和重合闸操作过电压的概率分布,提出必要的限制措施。通过计算分析认为系统的操作过电压水平要关注其频度分布。更多还原

【Abstract】 In this paper, level and distributing of switching overvoltage for the Yuncheng-Taian compact 500kV transmission line are calculated and studied. The probability distribution of closing switching and single reclosing switching overvoltage are analysed, and illustrated. The switching overvoltage level should pay attention to its probability distribution.更多还原
