By controlling the wind turbine to reduce load operation, a certain amount of power reserve is reserved and used to support system frequency modulation. This control method is called power reserve control. Pitch angle control and overspeed control are the two main control methods that can be achieved by this method. In the case of stable operation of the wind turbine, increasing the pitch angle can reduce the utilization rate of wind energy, thus generating a part of the reserve power. Furthermore, when the frequency of the system fluctuates, the pitch angle can be controlled to adjust the active power of the wind turbine The purpose of the effort.

By controlling the wind turbine, it is load-reduced, so that a certain amount of power backup is reserved to support the system FM, this control method becomes the power backup control. Pitch angle control and speed control are the two main control methods that can be achieved by this method. Under the stable operation of wind turbine, increasing the pitch angle can reduce the utilization rate of wind energy, so it produces a part of the backup power, and further, when the frequency of the system fluctuates, the control paddle angle can be used to achieve the purpose of regulating the effectiveness of the fan unit.

By controlling the wind turbine to reduce load, a certain amount of power reserve is reserved to support the system frequency regulation. This control method is called power reserve control. Pitch angle control and overspeed control are the two main control methods. Under the condition of stable operation of wind turbine, increasing the pitch angle can reduce the utilization rate of wind energy, so a part of standby power is generated. Furthermore, when the frequency of the system fluctuates, the active power output of the wind turbine can be adjusted by controlling the pitch angle.
