atp报错

lsx06

使用atp仿真时，仿真步长设的是1e-7，出现下列错误：

3 g7 E" y4 ^& \3 M Storage exceeded for EMTP List Number 8.   See the dimensioned limit in the case-summary statistics below.  The problem
' M# T1 Q' |4 ~6 }is simply too big for the program as currently dimensioned.
0 v$ u, s! [9 J- R8 C  H
我增大仿真步长可以消除错误，但是我又想要高的采样频率，该怎么办呢？
