| 摘 要： | 葛洲坝水电站根据周边电力负荷的发展情况，在2003年对大江电站两台厂用变进行升级改造，更新后的厂用变35kV电压等级通过单芯交联聚乙烯电缆直接敷设至附近的35kV变电站。本文35kV纯电缆线路单相接地故障，利用ATP—EMTP建立仿真模型，对故障现象进行分析，并给出35kV电缆线路运行改进建议。

| Abstract: | According to the surrounding power load development, Gezhouba hydropower plant had upgraded tow self-used transformation. On the side of 35kV voltage level, the single-core XLPE cables laid directly to the nearby 35kV substation. This article establishes pure cable lines 35kV single-phase ground fault simulation model, by using ATP-EMTP, to analyze the phenomenon of failure, and gives suggestions for improvement of 35kV cable lines run. |
