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.
! |7 m+ R/ E" N0 ^# L. FFor different model, the algorithm are different.
For example the most often used Bergron line,
. w0 h3 u0 O* B9 P# p! L* V( U& wThe results will be traveling time, surge impedance,Resistor and transformation matrix.
The 230KV, 60Hz, 100MVA is default value display on the program.
You can change those anyway.

Therefore, whatever you type, just for yourself reference, tline.exe doesn't use it.

Notice 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

9 z$ K, f6 b. G, q我是这样理解的
请高手指点

If the traveling time is larger than 2 time step, the above mentioned model is used.
( u& l  c5 ~  t6 ~% @9 [3 I" ?0 qIf 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。
