为了使风电机组可以在较短时间内调整输出功率并对对电网频率做出有效响应，

In order for the wind turbine to adjust the output power in a relatively short period of time and respond effectively to the grid frequency, the original power control link needs to be revised. Under normal circumstances, the auxiliary frequency control link does not play a role, but when the grid frequency is reduced, the wind turbine can reduce the rotor speed through the frequency control link, release part of the rotational kinetic energy, and convert it into a certain amount of active power to be input to the power grid. On the contrary, The control loop increases the rotor speed, absorbs part of the electromagnetic power from the grid, and at the same time converts it into kinetic energy and stores it in the rotor of the wind turbine, reducing active power output, thereby achieving the purpose of participating in grid frequency regulation.

In order for the wind turbine to adjust the output power in a relatively short period of time and respond effectively to the frequency of the grid, the original power control link needs to be corrected. Under normal circumstances, the auxiliary frequency control link does not play a role, but when the frequency of the power grid is reduced, the wind turbine can reduce the rotor speed through the frequency control link, release part of the rotating momentum, so that it is converted into a certain amount of functional input to the grid, on the other hand, through the control ring to increase the rotor speed, absorb some electromagnetic power from the grid, and at the same time convert to the wind turbine rotor, reduce the effective output, so as to participate in the power grid frequency regulation purposes.

In order to adjust the output power of wind turbines in a short period of time and make effective response to the grid frequency, the original power control link needs to be modified. Under normal circumstances, the auxiliary frequency control link does not play a role, but when the grid frequency is reduced, the wind turbine can reduce the rotor speed and release part of the rotational kinetic energy through the frequency control link, so that it can be converted into a certain amount of active power into the grid. On the contrary, the rotor speed can be increased through the control ring to absorb part of the electromagnetic power from the grid, and at the same time, it can be converted into kinetic energy storage It exists in the rotor of the wind turbine to reduce the active power output, so as to realize the purpose of participating in the power grid frequency regulation.
