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）

董版主：你是否可以不要用饱和的做一个接地变压器？另外，我的思路：利用开关3个测量电流的波形，让曲线相加得另序电流，不知可否？
接地变压器的接线就是114＃同志介绍的。我就不绘制了。
刚才我收到赵版主发来的电子邮件，他给我一张Z模型变压器仿真图，我还是看不明白。我感觉，还没有马老师的软件我做的仿真图概念清楚，可能是黄婆卖瓜自夸！
我今天仔细看了赵版主给我图，我不明白，Z模型变压器为什么用三个独立变压器组成？线圈之间为什么要用电阻连线？我了解他是省去了二次侧380V的所用电系统。我再次上传我的Z模型图，我非常想请大家能根据我的Z模型图变成ATPDraw的仿真图，请教了。
关注中，呵呵

ATPdraw里的Z型变压器是调用了饱和变压器模型，通过连接几个线圈得到的，我想应该符合舒老师的示意图的，我再看一下它的帮助文件，和舒老师给出的对比一下，看看问题出在哪里，空载励磁电流过大应该是励磁阻抗有问题吧

我觉得应该是可以吧， 正序，负序麻烦一些，零序应该可以直接数值相加吧，可以和继电的讨论一下
