DC line rectifier no longer controlling the order

Model CDC6T Two-Terminal dc line "1 " : At TIME = 0.8167 DC line rectifier no longer controlling the order

I am always getting this kind of error upon running dynamics simulation. Does it have something to do with .dlls that I cannot load on my case?

This is not an error!

It is just a message that the DC rectifier hits the minimum alpha angle limit and cannot maintain the power order.

The reason is that the simulated disturbance leads to decreased AC voltage at the rectifier side of the DC line. The model is behaving correctly.

I was thinking it was an error because after reaching the time 0.8167, the succeeding values are NaN. Any thoughts? Thank you so much

Is the initialisation (STRT) ok without suspect STATES? There areany messages about missing models? You write that you cannot load .dlls.

Yes, initial conditions were okay, except the issues I got for the .dlls. I haveloaded the .dlls and tried modifying the solution parameters and now it is okay. Thank you so much!

I am also facing a similar issue with DC rectifier not controlling the order. But all values become zero. STRT us ok without suspect STATES. What solution parameters where modified ?
