Abstract:
1. A wind-power generator control system, comprising: a wind turbine; a power generator, having a first output terminal and a second output terminal, and outputting a power output via the first output terminal and the second output terminal when the wind turbine rotates; a normally closed relay, connected between the first output terminal and the second output terminal; a control unit, transmitting a control signal to the normally closed relay by grid power, wherein when the normally closed relay does not receive the control signal, the first output terminal short-circuits the second output terminal by the normally closed relay; and when the normally closed relay receives the control signal, the first output terminal open-circuits the second output terminal by the normally closed relay; and a current-detection unit, detecting the current value of the first output terminal, and transmitting the current value to the control unit, wherein the control unit determines whether to provide the control signal to the normally closed relay according to the current value, wherein when the current value is less than a predetermined current value or greater than a rating current value, the control unit stops providing the control signal to the normally closed relay, and wherein when the current value is greater than the predetermined current, the control unit provides the control signal to the normally closed relay.
