摘要:
为研究碰撞调谐质量阻尼器(PTMD)在风浪联合作用下对海上单桩风机疲劳损伤的控制效果,以美国国家可再生能源实验室(NREL)的5 MW基准单桩海上风机为研究对象,利用拉格朗日方程建立风浪联合作用下单桩风机-PTMD系统的运动方程。考虑Kaimal湍流谱模型和Jonswap波高谱,分别得到随机风速时程和波浪荷载时程,基于Palmgren-Miner线性疲劳累积损伤理论及雨流计数法,分析了单桩风机-PTMD系统的疲劳损伤。结果表明:最优碰撞参数以及调谐频率下的PTMD能够显著减轻风浪联合荷载作用下风机的疲劳损伤,PTMD质量块无需过大行程即可满足风机实际使用要求; 即使在失谐情况下,PTMD仍具有较好的减轻风机疲劳损伤的作用; 提出的PTMD技术具有很好的应用前景,可在海上风电场中广泛应用,提升海上单桩风机塔身的安全性和疲劳特性。
Abstract:
In order to investigate the control effect of pounding tuned mass damper(PTMD)on the fatigue damage of offshore monopile wind turbines under the combined action of wind and wave, the 5 MW benchmark monopile offshore wind turbine provided by the national renewable energy laboratory(NREL)in the United States was taken as the research object, and the Lagrange equation was used to establish the motion equation of the monopile wind turbine-PTMD system under the combined action of wind and wave. Considering the Kaimal turbulence spectrum model and the Jonswap wave height spectrum, the stochastic wind speed time history and the wave load time history were obtained respectively. Based on Palmgren-Miner linear fatigue cumulative damage theory and rain flow counting method, the fatigue damage of monopile wind turbines-PTMD system was analyzed. The results show that the PTMD, with optimal collision parameters and tuning frequency, can significantly reduce the fatigue damage induced by wind and wave loads, and the PTMD mass block can meet the practical use requirements of the wind turbines without excessive stroke. Even in the case of detuning, PTMD still has a good effect on reducing the fatigue damage of the wind turbine. The proposed PTMD technology has a good application prospect and can be widely used in offshore wind farms to improve the safety and fatigue characteristics of offshore monopile wind turbine tower.
