摘要
通过分析多Π（或Ｔ）节线路模型的故障暂态特性，并与分布参数的输电线路行波特性比较，提出了衡量输电线路模型精确度的指标。通过ＥＭＴＰ仿真，得出了根据所研究的行波频率。
By analyzing the fault transient property of the multiple Π(or T) line models and comparing it with the travelling wave property of the distributed parameter transmission line, this paper presents a scale to judge the accuracy of the transmission line models, and proposes some general conclusions concerning the Π section length of the line models according to the travelling wave frequency studied .EMTP simulation shows that this approach is feasible and correct.
