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.

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.

Abstract: A control method for a wind power generating system includes the following procedures. When a rotational speed control condition is satisfied, a wind turbine is switched to operate under a rotational speed control mode to limit the electricity power by a maximum power point shifting manner. When a speed of an external wind is greater than a predetermined wind speed, the wind turbine is switched to operate under a safety mode to decrease a rotational speed of the wind turbine by a maximum torque extraction manner to protect the wind power generating system. A wind power generating system is also disclosed herein.
