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.
% p% k) t, i8 ~, S; YFor different model, the algorithm are different.
For example the most often used Bergron line,
' Z/ I+ J7 J& x9 t# m" |The 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.
' E! e' ~2 a) E4 CHowever, those three are not used in the program at all.
9 v+ y5 p/ w% A) m4 sTherefore, whatever you type, just for yourself reference, tline.exe doesn't use it.
You don't need to worry about it at all.

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
不过感觉不用担心吧
完全可以自己设置
( f6 b- B$ u* K) C. f2 N7 R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.
# [, B' @! E0 C% _- YIf 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。
