摘　　要：阐述基于混合配电网关键设备的暂态特性搭建PSCAD/EMTDC计算模型,探讨雷电侵入波在混合配网中的传播规律,分析避雷器配置方式。结果表明,环网柜内的过电压水平随电缆长度增加而下降。This paper expounds the construction of PSCAD/EMTDC calculation models based on the transient characteristics of key equipment in hybrid distribution networks, explores the propagation law of lightning invasion waves in hybrid distribution networks, and analyzes the configuration of lightning arresters. The results indicate that the overvoltage level inside the ring main unit decreases with increasing cable length.
