摘要
在分析雷击放电暂态过程的基础上 ,对雷电波形进行拟合 ,形成了雷电波模型。从基本 Bergeron模型出发 ,建立了计及双回线间参数耦合、以相量计算的扩展 Bergeron模型。针对 EMTP需重新计算初值的问题进行改进 ,在正常仿真中加入雷击前预处理过程 ,避免了初值的重复计算。
Based on analyzing lightning transient, model of lightning wave is built by curve fitting. From Bergeron model, this paper builds the extended bergeron model of six phase lines which calculates coupling in phase region. To solve problem of recalculating initialization in EMTP, a preparing process is added before lightning and recalculation is avoided. By simulation experiment, the lightning transient of six phase lines is investigated.
