摘要
以ITI Barge平台漂浮式风力机为研究对象,借鉴传统土木工程领域结构控制经验,提出漂浮式风力机MTMD结构控制方法,基于Kane方法建立漂浮式风力机多体动力学模型,研究并对比了风波流作用下有无MTMD时风力机的结构动力学响应特性,并进一步基于多岛遗传算法对MTMD系统进行优化。结果表明:MTMD控制效果较好;所提出优化算法获得的优化参数具有更加明显的控制效果,塔顶侧向位移与平台横摇运动均得到了明显的抑制。不同环境工况下,MTMD都对漂浮式风力机有着明显的控制效果。其中纵向载荷标准差抑制率为78%~83%,横向载荷标准差抑制率为14%~18%。
By floating wind turbine of ITI Barge platform as the research object,floating type wind turbine MTMD structure control method was put forward. The storm flow under the action of the presence of MTMD structure dynamic response characteristics of wind turbine was studied and compared. Based on MIGA,the optimal parameters of MTMD system was calculated. The result showed that MTMD control effect was better; MIGA could optimize MTMD parameters effective; After parameter optimization,MTMD had obvious control effect on floating wind turbine,the standard deviation inhibition rate of the tower longitudinal displacement and platform roll angle improved respectively; MTMD had obvious control effect for floating wind turbine in different environmental conditions,and the standard deviation inhibition rate of the longitudinal load was 78% - 83%,the lateral load was 14% - 18%.
