With the substantial increase of the installed capacity of wind power, it has brought great challenges to grid stability and safety. In order to improve the grid stability and the anti-interference ability of grid frequency, wind farms urgently need to have frequency regulation function and increase frequency response speed. According to the latest technical requirements such as starting time and adjustment time of grid, this paper analyzes the current mainstream frequency regulation schemes in the market. A frequency regulation scheme combining energy management platform and frequency regulation equipment is proposed, so that the wind turbine receives instructions from the energy management platform and frequency regulation equipment at the same time, and adopts different control strategies for inertia response and primary frequency regulation to adjust the active power of the wind farm to ensure the response speed and stability during frequency regulation.The scheme has been tested for inertia response and
