Abstract: A doubly-fed wind turbine generator set, a power system and a control method thereof are provided. The generator set includes a first grid-connected transformer, at least two circuit breakers, at least one grid-side converter, a stator, a rotor and at least one machine-side converter. The at least two circuit breakers are respectively coupled to the first grid-connected transformer and matched with at least two contactors. Each grid-side converter has a respective Alternating Current (AC) side coupled to the circuit breakers and is coupled to the first grid-connected transformer. The stator is equipped with at least two electrically independent windings, each coupled to a separate contactor. The rotor includes a set of rotor windings and at least one rotor slip ring. Each machine-side converter has a respective AC side coupled to the rotor slip ring, and a DC side coupled to that of the grid-side converter via a capacitor bus. Figure 14 is the representative figure.
