支持楼主，但是我下载后解压出错，不能用啊。楼主好心可不可以发邮件给我：xeqja@163.com，另外我有一个问题，在论坛上问了好久没有人回答，问到客服，很悲催地被要求提供软件授权号，你懂的，在天朝国度里像我这样的小白只能用一用石皮解，哪里有授权号，楼主可否顺便帮我把问题给回答了：
请教大侠们，我在做pscad变压器仿真时遇到一个问题很不懂：
umec模型中考虑饱和情况下，设置的U-I曲线与仿真结果总对不上，例如我把一个系统默认的umec变压器模型来做空载试验模拟，模拟的电源用理想电源，依次施加不同的电压测量其空载电流，仿真测量的U-I曲线与Saturation Curve设置窗口中对应标幺值换算的U-I曲线差别很大，这是为什么呢？应该是一样的才对啊！

问题原文Dear Sir/Madam:
I'm a beginer of the PSCAD software (version 4.2.1) , and I have a question about UMEC transformer model during learning. Would you please help me?I will be very grateful to you if you give me an answer or give me some clews.
The question is about the UMEC transformer model in PSCAD 4.2. For the UMEC transformer, why is the measured no-load current not equal to the set value in saturation curve?
For example, the transformer illustrated in the following circuit(Figure 1) is a model from the Master Library without any change, its rated power is 100MVA, and its rated voltage is 230kV(Figure 2). According to the saturation curve, its no-load current should be I0=100MVA/230kV*2%=8.7A, but in the no-load test simulation (In Figure 1. a ideal power supply is used), the measured no-load current is 2.61655A, which is quite different from the set value.
The whole Saturation Curve is simulated as well. The comperation of measured value and set value of saturation curve is shown in Tabel 1 and Figure 3.

I wish I have discribed the question clearly, and look forward to your feedback.
Best regards
