Answer to Question 1

In the case of an asynchronous motor, the rotor spins less than the synchronous speed of the field; as a generator, it spins faster than the synchronous speed. An induction generator always starts out as an induction motor until it passes the synchronous speed.

Answer to Question 2

The synchronous generator is can receive voltage from the grid and act as an electric motor if the blades are not turning to help start it in low winds. After coming up to speed, the wind can take over.
