为实现海上风浪资源的高效利用,以Windfloat型风力机平台为基础,结合摇臂式波能装置,建立联合获能系统数值模型,并分析了波周期、PTO（power take-off）阻尼、浮子直径及摇臂长度等关键参数对联合系统运动与获能的影响。研究发现,随波周期的增大,平台运动幅度整体呈增大趋势,装置获能先增大后减小;随PTO阻尼的增大,平台纵荡、纵摇运动幅度逐渐减小,垂荡运动幅度及装置获能先增大后减小;随浮子直径、摇臂长度的增大,平台纵荡运动幅度逐渐减小、垂荡、纵摇运动幅度逐渐增大,装置获能随浮子直径的增大而增大,随摇臂长度的增大先增大后减小。
Abstract
In order to achieve the efficient utilization of offshore wind and wave resources, a numerical model of the combined system is established based on Windfloat wind turbine platform combined with rocker wave energy converters, and the effects of key parameters such as wave period, PTO （Power take-off） damping, buoy diameter and rocker length on the motion and energy acquisition of the combined system are analyzed. It is found that with the increase of wave period, the overall motion response of the platform tends to increase, and the energy acquisition of the converters increases first and then decreases;with the increase of PTO damping, the surging and pitching motion of the platform gradually decreases, the heaving motion of the platform and the energy acquisition of the converters increases first and then decreases;with the increase of buoy diameter and rocker arm length, the surging motion response of the platform decreases gradually, heaving and pitching motion response increase gradually, the energy acquisition of the converters increases with the increase of buoy diameter, and increases first and then decreases with the increase of rocker arm length.
