关于避雷器的问题

vien

我搭建了一个利用避雷器限制投切并联电容器组操作过电压的模型，未加避雷器就ok，但是加上避雷器后运行总是出错。
( M" w! I" Z% j  _9 g比如加上避雷器后，如果电容器上有量相间电压的电压表，就会出现下面的出错信息：

把三个电压表移除就可以运行。
如果线路中有重合闸，加上避雷器会出现如下出错信息：

已经试了很久，还是找不到解决办法，实在没辙了，请各位帮忙，万分感谢。

其实就是加上避雷器后不收敛了，原来我仿真时也碰到这个问题了
可以试着把这个参数改大一点
7 v0 K4 u2 Q9 _ErrLim= Fitting tolerance in pu
你输入的伏安特性时数据表吧

vien

之前有个加相地间避雷器的模型，我把ErrLim设定成1之后可以运行，但是还是不能加不接地电压表probe branch volt，加了之后还是会出现KILL = 209。
) {- s( `6 ?6 s) R) T& w# U& ?现在新遇到一个极间避雷器和中性点避雷器的模型，什么电压表都不加还是会出错。
还有，避雷器伏安特性从哪查啊？

  _3 u+ E5 M/ K6 h8 n' n2 X就是这个模型

模型

回复 2# wangdc
+ B4 X8 ^/ e, f2 _: I您好，谢谢您的回答。我看到您在ATP这个版块的很多回复，您现在对这个软件的掌握应该不错吧？有问题还请您多指教。

wangdc

呵呵
也是现学现卖
大家多交流才能不断进步
伏安特性就是在模块中characteristic填写或采用文件输入指数

回复 8# laoshouren
  a7 r! L7 k' i* m# M
+ T9 W8 a' X2 C5 r, k& {9 s! J9 y当然是查到的，伏安特性不太好查，最好能找到你采用避雷器厂家给定的参数，对照  i=p*(u/Vref)^q这个公式算出来，然后填进去。
