三天过去了，我踏着年轻人的肩膀上，偷偷地偷董版主的拳头，慢慢地摸索着他的手艺。我做了董版主为我提出的问题的仿真图。我记得他做出仿真图以后，我曾经提出要在各条出线路加负荷，以便更真实的反映实际情况，我斗胆的在他基础上进行修改，仿真后，各线路的的电流就完全不如董版主在四条空载线路，线路1号末端A相接地暂态过程那么明显。这是因为所有都是空载的，所以可比较。今线路有负荷，各线路上就有大于电容电流的数值，那么使故障线路的电流特征就没有了。这也是我最初的本意，即我是要千方百计的求得穿过电缆的另序CT的仿真模型。我又在想，如果ATPDraw能够在开关上三个电流曲线能相加，不是可以得到该条出线的另序电流了吗？

我忘记了上传仿真模型图和ATP运行文件。现在补上。
另外，我要请教版主，我运行董版主的提供的10kV_reactor.acp文件后，F5打开OUT，发现，10KV主变开关的电流，不等于各路出线线路开关的电流之和？

舒老师观察的很细致，各处开关的电流之和的确小于总开关的电流，那是因为我没有在接地变压器处添加开关，缺少的那部分电流正是变压器的励磁和损耗电流，我对接地变压器不熟悉，参数可能设置的不太合理，期待着舒老师把这个模型继续完善！
我老头是真是昏了头，我把文件是传错了。
董版主：你好。“接地变压器不熟悉，参数可能设置的不太合理，期待着舒老师把这个模型继续完善！”，我是想偷着学习，可惜，我把你的接地变压器模型打开，我可以说基本看不懂。不个，我发现，这个Z型变压器可能有问题，接线组别是Z/D1。但是，它的二次侧380V所用电电压是不会受外面10KV线路单相接地而变得不对称。我将继续努力学习和请教。
atpdraw里的Z型变压器的模型我并没有深入了解, 参数可能不太合理, 希望舒老师可以深入的研究, 给大家讲解一下.
我把董版主提供的仿真图及仿真运行数据文件中，暂时去掉Z型变压器以下部分，进行了二个仿真运算，都是稳态计算。第一个，结果表明：四条空载电流之和等于10KV总开关电流。第二个，线路出线1末端 A相接地后，10KV总开关电流与四条线路的电流关系，都符合电工原理。基本可以说明Z型变压器模拟可能是有问题。我现在在阅读ATODraw5.5关于变压器模型的填卡说明书，因为全部是英文，我确实学习很困难很困难。我笨办法，打印出来，请教单位里能人翻译。因为我存在电脑是文本格式，不能上传，我只好压缩后上传。
舒老师，有z型变压器也是符合电工原理阿，它也需要励磁电流和损耗，必然分走一部分电流，可能参数设置的不合理，使励磁电流偏大了
你说得对，但是一个空载接地变压器他不可能有15A的电流？我看了F4、F5，你的Z型变压器设置好像是有问题，我已经想了二天了，我在比较我过去的马老师软件做的接地变压器参数，好像不一样，我也不知什么原因。
根据你的仿真图运行后：
这是接地变压器的参数（F4得到）
