Abstract The invention discloses a method and system for coordinated control of wind energy harvesting and stability of deep-sea semi-submersible wind turbine, which includes a sensing detection device, a data processing and control device, a yaw device, a floating platform stability adjustment device and a display device. the wind turbine yaw mechanism needs to be activated to rotate the nacelle against the wind. The aerodynamic load changes during the yaw operation, and the changed aerodynamic load is transmitted to the floating platform through the wind wheel, nacelle, and tower, and the floating platform stability adjustment device collaboratively assists. During the operation of the yaw device, the floating platform stability adjustment device adjusts the balance of the floating platform simultaneously to achieve the best yaw-against-wind effect and capture wind energy as much as possible; This invent can automatically have coordinated control of the semi-submersible wind turbine to yaw against wind precisely without human operation, increasing the power generation efficiency of the offshore wind turbine greatly. -4 Fig.1 Fig.2 19 i8 17 Fig.2
