PURPOSE: A wind power generator is provided to continuously generate power even through being cut off from a system, thereby reducing restart time when the system is restored. CONSTITUTION: A wind power generator comprises a first converter (320), a capacitor (C), a second converter (340), a transformer (520), a breaker (540), and a control part (600). The control part controls the first and second converters. The control part outputs first and second control signals to the first and second converters to operate the first converter as a DC link voltage control mode and the second converter as a voltage control mode when the breaker cuts off the connection of the transformer and the system. The control part outputs the first and second control signals to the first and second converters to operate the first converter as a torque control mode and the second converter as a current control mode when the breaker connects the transformer and the system. |
