摘要：

Under the external environment load, the posture of floating platform of offshore wind turbines is always changing, and the instability caused by platform tilting will endanger the safety of the turbines. Therefore, a stability control strategy for three-bucket floating platform is proposed. In this strategy, the posture sensor is used to detect the real-time change of the floating platform's posture angle, and the coordinate transformation between dynamic coordinate system and static coordinate system is employed to convert the change of the posture angle into the height change of the floating buckets. Then, the dynamic regulation strategy of ballast water is designed to distribute the ballast water in real time, which can change the quality distribution of the platform to maintain platform stability. On this basis, a platform stability control system based on embedded micro-controller is designed which faces the future requirement of special controller for floating platform of offshore wind turbines. Finally, an experimental model of offshore floating wind turbines in laboratory is developed and the stability control experiment of the floating platform is carried out. The results show that the stability control system can effectively restrain the dynamic change of the floating platform and keep the platform stable. © 2021 Journal of Mechanical Engineering.
