关于MOA仿真问题

在晶闸管上并联了一个MOA，结果运行后出现了以下错误，请高手解答啊？谢谢了
TrustRegion-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues.
To rule out solver convergence as the cause of this error, either
a) switch to LineSearch-based algorithm using
set_param('power_svc_1tcr3tsc','AlgebraicLoopSolver','LineSearch')
b) reducing the VariableStepDiscrete solver RelTol parameter so that the solver takes smaller time steps.
If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification.

无解 ，不收敛！根据提示修改。

应该怎么解决收敛问题呢？一般问题出在哪啊？前辈
