You lose, fella. The EMTP logic has detected an error condition, and is now going to terminate program execution.The following
message summarizes the circumstances leading to this situation.Where an otherwise-unidentified data card is referred to, or where
the "last" card is mentioned, it is the most recently read card of the input data that is meant.The 80-column image of this card
is generally the last one printed out prior to this termination message.But possibly this last-read card has not yet been
displayed, so a copy follows:
" "
KILL code number Overlay number Nearby statement number
212 18 3522
KILL = 212. A Newton solution for1 coupled nonlinear elements has failed to converge within the iteration limitMAXZNO = 50.
The current residual is1.24294193E+04,which exceeds the sloppy convergence toleranceEPSTOP = 1.00000000E-01. The first of
the coupled, true, nonlinear elements (in order of data input) is located in row1 of the nonlinear element table, and it
connects node"X0001A"with node"B ". The final coupled element is in row1, and the matrix rank is1. Finally, the
simulation time isT = 4.05000000E-07. Possible corrective actions include a decrease in the time-step sizeDELTAT,an increase
in the iteration limitMAXZNO,an increase in the divergence toleranceEPSTOP,and artificial splitting of the subnetworkin
question by distributed-parameter lines (to reduce the number of coupled elements). In addition, it is possible for the user to
make a solution impossible by unrealistically limiting the Newton corrections.The user should remember that there can be no
solution if his bound on arrester voltage is less than the true solution voltage.The bound has a default value of 1.5 per unit,
although it can be changed by a"ZINC OXIDE"special request (columns 57-64, variableZLIN(2)).

Totals: 0.063 0.000 0.063 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 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。 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
可能输入指数好一点
期待高手指点啊 可以将参数ErrLim调大一点
但是是否合理就不清楚了 本帖最后由 guozh07 于 2010-11-1 20:59 编辑
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）避雷器参数设置有问题，残压是否太低？ 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
请斑竹指点啊 我是按照特高压避雷器的参数输入的就是不知道如何改 版主EPSTOP = 1.00000000E-01MAXZNO = 50.这两个是什么意思啊？
应该怎么改啊 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？ 加个好友吧，qq543245091，一起学习学习
