摘要

浮式海上风力涡轮机(FOWTs)受到风和波的联合载荷,会经历显著的俯仰运动,导致能量产生减少,结构损坏增加。本研究提出利用被动陀螺稳定器作为缓解这些问题的有效解决方案。首先,利用内部仿真工具开发了含被动陀螺稳定器的半潜式FOWT的耦合动力学模型。在此框架下,研究了陀螺稳定器数量和布置策略、陀螺转子转速和进动阻尼系数对其减节的影响。分析了陀螺稳定器在不同风浪条件下的性能,找出了影响陀螺稳定器性能的关键因素。最后,采用遗传算法对无源陀螺稳定器进行参数优化,最大减距率达到93.8%。然而,当考虑陀螺稳定器的功耗时,确定了优化的俯仰降低率为80.7%。这些发现为陀螺稳定器在fot应用中的潜力提供了有价值的见解,并标志着该领域最新技术的重大进步。

Sensitivity analysis and optimization of passive gyrostabilizers to mitigate pitch motion of a semi-submersible floating offshore wind turbine
Floating offshore wind turbines (FOWTs) subjected to combined wind and wave loads experience significant pitch motion, resulting in reduced energy production and increased structural damage. This study proposes the utilization of passive gyrostabilizers as an effective solution to mitigate these issues. Initially, a coupled dynamic model for a semi-submersible FOWT incorporating passive gyrostabilizers was developed using an in-house simulation tool. Building on this framework, the study investigated the effects of gyrostabilizer quantity and arrangement strategies, gyro-rotor speeds, and precession damping coefficients on its pitch reduction. Additionally, the performance of the gyrostabilizers under varying wind and wave conditions was analyzed to identify key influencing factors. Finally, genetic algorithm (GA)-based parameters optimization of the passive gyrostabilizers was conducted, achieving a maximum pitch-reduction rate of 93.8 %. However, when accounting for the power consumption of the gyrostabilizers, an optimized pitch-reduction rate of 80.7 % was identified. These findings contribute valuable insights into the potential of gyrostabilizers for FOWT applications and signify a significant advancement in the state of the art in this field.
