Initial conditions solve fail to converge in a trivial model

Hi
I am trying to build a model of a simple microgrid using SimPowerSystems elements. The microgrid contains two synchronous generators in parallel connected to a substation which feed a synchronous motor. I see this error every time I run the simulation: "Initial conditions solve fail to converge" and a detailed report of the equations of various elements which may have caused the problem (and I don't know how these errors could be solved)
Then I simplified the model, incrementally building it, and I saw this error at the very beginning. (File is attached) This model has a Sync generator, a step-up transformer and two three phase loads, delta: RC & Y: R.
Anyone has encountered the same problem, or have an idea? P.S: I reduced the consistency tolerance to 5e-6 (as suggested in Simulin help), but the problem didn't resolve.

You should check parameters of the transformer and the generator. Read help for the each model.
