| 摘 要： | 在分析计及耦合的双回输电线路波过程的基础上，建立了双回线的扩展Bergeron模型，以此为出发点针对线路故障的电磁暂态仿真问题，对EMTP的耦合线路故障预处理方法进行了改进，使系统无需重新进行初始值及稳态计算而应用历史值即可完成新增短路节点的计算，该算法在分析双回线路任意点故障的电磁暂态以及线路保护仿真校验等方面具有重要意义。

| Abstract: | Based on the analysis of travelling waves of coupled parallel transm ission lines,the extended Bergeron model is established.Considering the electromagnetic transient process of the fault on lines,this paper improves the pretreatment method of EMTP fault calculation to finish the sim ulation of increasing the fault point without calculating initial value and stead- state of the whole system again.This method is im portant to the analysis of the electromagnetic transientprocess of the random faults on lines and the tests of the transmission line protection. |
