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。

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
ErrLim= Fitting tolerance in pu
/ G, l# P8 z' Q7 F/ o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。
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？

vien

就是这个模型

( V; @, E8 X; h8 H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。

呵呵
也是现学现卖

$ o7 W$ z% e) C5 k) ?; ^& s$ q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。
