关于tline.exe的，高手必看

有谁知道tline.exe的程序流程的计算规则么，现在据说此系统的默认的参数设置是 100MVA 60Hz 230kv 基准值的处理过程，大家使用的时候，一定得小心的啊！

The TLINE program is used to calculate parameters of traveling wave lines.

The 230KV, 60Hz, 100MVA is default value display on the program.

However, those three are not used in the program at all.
Therefore, whatever you type, just for yourself reference, tline.exe doesn't use it.

There is some description of tline algorithm in chapter 4 of EMTP theory book.

However, basic theory would be the same.

使用的时候，计算结果假设了R G 均为0 的啊，或者是采取了 Bergron 的数据模式 线路的周末两端均为人R/4 ，线路中间的为R/2，两端LC均为分布特性的传输线

这个倒是没有注意过

If the traveling time is larger than 2 time step, the above mentioned model is used.

受益了的啊，谢谢版主的了的啊

没有用过，不过感谢楼主的提醒。
