摘要/Abstract

摘要： 在外部环境载荷作用下，海上风电漂浮式平台姿态始终动态变化，倾斜失稳会危及整个机组安全。为此，提出一种海上风电三浮筒式漂浮式平台稳定性控制策略。该策略通过姿态传感器感知漂浮式平台实时姿态角变化，借助动、静坐标变换技术将姿态角的变化转换为各浮筒高度变化。然后，进一步设计出压舱水动态调节策略，实时分配各浮筒内部压舱水水量，从而改变平台质量分布以保持平台稳定。在此基础上，面向未来海上风电漂浮式平台专用控制器发展需要，设计了一套基于嵌入式微控制器的平台稳定性控制系统。最后，开发了海上漂浮式风电机组试验模型，并进行了漂浮式平台稳定性控制试验研究。结果表明，提出的稳定性控制系统能够有效抑制漂浮式平台的动态变化，保持平台稳定。

Abstract: 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.
