Abstract: A wind-power generator control system is provided. The wind-power generator control system includes a wind turbine, a power generator, a normally closed relay, and a control unit. The wind-power generator has a first output terminal and a second output terminal, and outputs a power output via the first and second output terminal when the wind turbine rotates. The normally closed relay is connected between the first and second output terminals. The control unit transmits a control signal to the normally closed relay by grid power. Also, 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 for protecting the wind-power generator. When the normally closed relay receives the control signal, the first output terminal open-circuits the second output terminal by the normally closed relay for providing the power output.
