Why do the load flow results from the powergui block in my IEEE 34 model only appear for buses before the voltage regulator, and how can I fix this?
It looks like the implementation for the regulator isn't supported for load flow, aka, the tool can't do load flow through the O...

I put a breaker model in my circuit. And i found that it closes when the current is zero and the external signal is 0.
The model is not implementing a voltage breakdown. The issue is most likely with the input signal that you are using, or the so...
