摘要
安装线路避雷器后,传统的各防雷性能参数计算方法失效,对线路防雷的分析产生极大的影响。利用电力系统电磁暂态仿真软件(ATP-EMTP)对安装线路避雷器后的耐雷水平和分流系数进行仿真计算,可有效提高对线路的安全保护,其计算便捷,结果准确。重点介绍了计算方法和计算过程。
The traditional calculating methods of lightning performance parameters are failed when the lighting arrester is installed, which strongly influences arrester analysis. By the alternative transient program/electrical- magnetic transient program (ATP-EMTP) software, the lightning withstand level and shunting coefficient are being simulate studied after lightning arrester installed. It improves the safety protection effectively, calculates conveniently and gets correctly result. The calculating methods and process are introduced.
