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.
5 w+ f/ O) d. p, o# BFor different model, the algorithm are different.
8 [# N3 S4 L8 z0 pFor example the most often used Bergron line,
The results will be traveling time, surge impedance,Resistor and transformation matrix.
The 230KV, 60Hz, 100MVA is default value display on the program.
& q5 f5 c2 _0 R! ?, i4 `You can change those anyway.
, C" r$ ~$ Y4 @: V0 d' ?- l3 L% [& o/ KHowever, those three are not used in the program at all.
Therefore, whatever you type, just for yourself reference, tline.exe doesn't use it.
- C* K4 {9 z: ~- x1 H! BYou don't need to worry about it at all.
There is some description of tline algorithm in chapter 4 of EMTP theory book.
& g: k  ~" ~. x( n5 h* LNotice that tline.exe is written by EMTDC people, it may not be exactly the same as EMTP.

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
  D& E' \8 z, A! c+ i0 G2 F不过感觉不用担心吧
完全可以自己设置
$ H# b! p2 R5 H5 _* m: C我是这样理解的
( C0 K1 |! L$ U请高手指点

If the traveling time is larger than 2 time step, the above mentioned model is used.
' H" o) l- f: }- hIf the traveling time is between 1 and 2 time step, the resistor is halfly lamped at two terminals.
If the traveling time is smaller than 1 time step, the PI section has to be used, or the user has to reduce the time step.

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。
