The invention discloses a cooperative control method and system for wind facing energy capture and stability of a deep sea semi-submersible wind turbine generator system. The cooperative control system involves a sensing detection device, a data processing and control device, a yawing device, a floating platform stability adjusting device and a display device. When the wind speed and the wind direction are greatly changed, the yawing device needs to be started to rotate a cabin to face wind, in the yawing process, the aerodynamic load borne by a wind wheel is changed, the changed aerodynamic load can be transmitted to a floating platform through the wind wheel, the cabin and a tower, and the floating platform stability adjusting device assists in cooperation; and in the operation process of the yawing device, the floating platform stability adjusting device adjusts the balance of the floating platform at the same time, so that the semi-submersible wind turbine generator system achievesthe optimal yawing wind facing effect, and wind energy is captured as much as possible. According to the cooperative control method and system for wind facing energy capture and stability of the deepsea semi-submersible wind turbine generator system, the semi-submersible wind turbine generator system can be automatically coordinated and controlled to accurately yaw and face wind, manual operation is not needed, and the power generation efficiency of the offshore wind turbine generator system is greatly improved.

    本发明公开了深海半潜式风电机组对风获能及稳定性协同控制方法及系统,包括传感检测装置,数据处理及控制装置,偏航装置,漂浮式平台稳定调节装置和显示装置。当风速风向变化较大时,需启动偏航装置转动机舱对风,在偏航过程中,风轮所受气动载荷发生变化,并且变化的气动载荷经过风轮、机舱、塔架会传递至漂浮式平台,漂浮式平台稳定调节装置协同辅助,在偏航装置运行过程中,漂浮式平台稳定调节装置同时调节漂浮式平台的平衡,使半潜式风电机组达到最佳偏航对风效果,捕获尽可能多的风能。本发明能够自动协调控制半潜式风电机组准确偏航对风,无需人为操作,大大提高了海上风力发电机组发电效率。
