我做的是输电线路防雷  加的是线路避雷器  可是运行时出现这问题  一直没解决，所以请教各位，我将我的仿真图形附上，请大家看看

liushuaige0919

我的理解是Vref是一个初值，emtp拟合伏安特性曲线用的是牛顿拉夫逊法，你初值隔太远就不会收敛。

wangdc

避雷器参数设置的问题
我也遇到了同样的问题
但也没有很好的解决
我输入的时伏安特性点
/ t. n4 i9 ?- L8 }- M1 @) M可能输入指数好一点
期待高手指点啊

wangdc

可以将参数ErrLim调大一点
但是是否合理就不清楚了

guozh07

0 X1 W1 M* S" K4 V至少要检查：
6 w8 [: l7 l6 @9 _1）计算步长是  T = 4.05000000E-07.   要看看你的元件设置，特别是最短的线路单元有多长，如果线路分段很短，减小计算步长。
: _& F, P/ G( ~! c) H: C9 V2）避雷器参数设置有问题，残压是否太低？

wangdc

报错的信息里说是残压低
但是输入的是实际的避雷器的伏安特性时也会出现这种情况啊
还有如何修改MAXZNO = 50？这个参数啊
4 s- D6 d. ~+ P! l' g  {8 x) o8 W请斑竹指点啊

jinghaibing

我是按照特高压避雷器的参数输入的  就是不知道如何改

jinghaibing

版主  EPSTOP = 1.00000000E-01  MAXZNO = 50.  这两个是什么意思啊？
应该怎么改啊

jinghaibing

版主，请问避雷器参数设置中，Vref这个参数是指避雷器的额定电压吗？
