How can I use the simplfied synchronous generator in SimPowersystems in a phasor simulation type?

power_simplealt can be switched to phasor mode, there will be a small perturbance at start, but then it works.

Initialization commands cannot be evaluated.

You would need to share a model for this type of error to be debugged.
