摘 要:基于10 kV配电线路,分析了直击雷和感应雷过电压线路的耐雷水平,通过ATP-EMTP仿真软件分别建立了直击雷和感应雷过电压的仿真模型。仿真结果表明加强绝缘强度、架设避雷线、安装避雷器、降低接地电阻等防雷措施能有效提高配电线路的耐雷水平,降低雷击跳闸概率,提高供电可靠性。

Abstract: Taking 10kV distribution line into consideration, this paper calculated the lightning withstand level of direct lightning overvoltage and induced overvoltage by theoretical analysis, and established the simulation models of direct lightning overvoltage and induced overvoltage by ATP-EMTP to verify the theoretical value. The simulation results indicated that lightning protection measures such as reinforcing insulation strength, installing ground wire and lightning arresters and reducing the grounding resistance can improve the lightning withstand level of distribution line effectively, reduce the lightning trip probability and improve the reliablility of power supply.
Key words: distribution line; lightning withstand level; simulation software ATP-EMTP; lightning protection measure
