How to debug an error from the powergui block.

I have got a message that says:

I have monitored the states and they look like this:

:

then found the source of those state oscillations:

and thats it, i cannot find the actual block in my Simulink model that produces those state oscillations. My Simulink model is a big power network combined with Power Electronic elements. Personaly, I suspect, it is a wrong inductance value, but How to find the actuall block or element that is linked to EQUIVALENTMODEL1 ? is there a way to debug in more details?

Thanks

Hi TeraWatt,

It appears to me that you are having trouble in debugging the powergui block. Setting “breakpoints” in Simulink is one method of error debugging.

Kindly refer the below documentation to know more about how to debug simulation using breakpoints in Simulink: https://www.mathworks.com/help/simulink/ug/conditional-breakpoints.html
