EXPERIMENTAL STUDY OF PHYSICAL MODEL OF WAVE ENERGY CONVERTERS ON FIXED WIND TURBINE FOUNDATION

近年来,随着传统化石燃料消耗日益增多和环境保护问题日渐严峻,海上可再生能源的发展越来越受到重视,海上风能和波浪能利用技术成为研究热点。该文提出一种基于固定式四脚导管架海上风力机基础的振荡浮子式波浪能装置,从能量守恒角度进行理论分析,开展几何比尺1∶8的物理模型试验,研究海上风能和波浪能耦合利用的可行性,分析波浪能装置对风电机组基础周边波浪场的影响并总结规律。研究发现:应针对特定海域的波高和周期条件挑选合适的浮子,且单个侧面浮子比单个正面浮子的能量吸收率更高、对波浪场的遮蔽作用更明显,为海上风浪耦合利用提供了理论依据和设计参数。

In recent years,the development of offshore renewable energy is receiving increasing attention,with the following consumption of the traditional fossil fuel and the increasing serious problems of environmental protection.Among these renewable energies,the offshore wind energy and wave energy are becoming the research focus.An oscillating buoy type wave energy converter based on fixed four-feet-jacket offshore wind turbine foundatio is proposed in this paper.Theoretical analysis is conducted from the perspective of energy conservation,and the physical model experiment of geometric scale 1∶8 has been carried out.According to the experiment,the preliminary feasibility are studied,and the effects on the surrounding wave field of wave energy converters are evaluated.The results indicate that appropriate buoys should be selected according to different wave heights and periods in specific areas,and the shielding effect on the wave field of single lateral buoy is higher than that of frontal one.These conclusions provide theoretical basis and design parameters for the coupling utilization of offshore wind and wave energy.
