摘要
在常用的EMTP及其他一些电路计算软件中,没有频变元件的设定方法,造成在宽频率的瞬变过程计算中准确度降低。针对于此,笔者提出3种方法:开关接入及短接元件法、圆导体分层法、并联电阻—电感支路法,它们各适用于各种不同的电路情况和元件种类。文中还提出提高仿真准确度和简单校核的方法。
Because there are no frequency-dependent elements in EMTP and some other softwares,three simulation methods of frequency-dependent elements were deducted in this paper.They are switching method,laying method for cylinder conductors,and parallel R-L branch method.Each of them is suitable for different conditions individually.Some suggestions are proposed for increasing the accuracy as well.
