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
' J( u6 Y, |9 k( O我也遇到了同样的问题
; `% r8 z- w2 x6 @2 a但也没有很好的解决
我输入的时伏安特性点
% M3 u+ m9 x- j' Z6 u7 A2 a9 U可能输入指数好一点
/ V9 x) w& g+ s8 c. }$ t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

4 V; o" x. k/ f1 h* l
6 C1 G* h0 ~! r( Q0 r# j- c至少要检查：
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。
2 |/ K/ L% w) u; U& Y5 q) ~2）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
8 h3 f+ y6 \  m/ S. E) w' v" {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
3 z1 D7 d# ?, o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？
) j9 z9 f$ [& n, g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？
