You say from the second point. Is it s snapshot?
If you selelt it begin at a snapshot,then the nitialization  procedure has already builted.

If you are really interested in EMTDC, please read the manual carefully, and you should also read EMTP theory book and take power system analysis courses in university
Those programming tip/detail is no that important, but sometime fun...

I have read the manual once only, and have no oportunity to take power system analysis courses, hope I can depend on myself..

你可以做个实验的啊，就是建立最基本的一个三相电源，然后把测试这个电源的电压，用理想电源模块1 ，然后看看out文件里面，三相电源的各点的情况，你会发现的啊，当然上升时间为0，你看看结果

the issue is that i can't use properly this model which is discribed as " RTP recorder" , can you give me a hand.

xuyufufzu

i want to simulate the transmission line model,and i can't understand it very well in the PSCAD,i don't know where to find principium of the transmission line model including the coupled  pi section .
although i can understand how to calculate the parameters in the power system analysis.what can i do for understanding it well in the PScad.
SORRY ,my english is not very well .but i want to give my thanks to you!

OK, I got it. You are talking about the RTP recorder.
