摘要
海上风能资源储量丰富,促进了海上风力机的发展.随着风力机功率的增大,适用于浅海海域的固定式基础已经不再满足设计要求,适用于深海海域的浮式基础得到了快速发展.本文介绍了浮式风力机的发展过程、类型以及特殊性,指出了水池模型试验在浮式风力机的发展过程中起着不可或缺的作用.本文首先总结了缩尺模型试验的关键技术,然后以上海交通大学提出的6 MW单柱式风力机为研究对象,总结了缩尺模型的制作过程,最后介绍了上海交通大学海洋工程深水试验池的建设情况,并展示了在该试验池中进行的新型多立柱张力腿式风力机模型试验的结果.其试验结果与软件计算结果吻合较好,表明该试验池可以很好地开展浮式风力机的模型试验.本文对于后续的6 MW单柱式风力机模型试验及众多的风力机模型试验具有一定的指导作用,为我国浮式风力机的发展提供了理论依据.
The abundance of offshore wind energy resources has promoted the development of offshore wind turbine.With the increase of wind turbine power,the fixed foundation for shallow sea area no longer meets the design requirements,and the floating foundation for deep sea area has been developed rapidly.In this paper,the development process,types and particularity are introduced,and it demonstrates that the model experiment is indispensable in the development of floating offshore wind turbine（FOWT）.Firstly,key technologies of basin model test are concluded,such as similarity criteria,scale ratio determination technology,model blade design technology,mooring system processing technology and environmental conditions simulation technology.Then object of 6 MW SPAR-type FOWT proposed by Shanghai JiaoTong University is researched,and production process of model is summarized,including model blade,model nacelle and model tower.Finally,the construction of the deep water test tank of marine engineering of Shanghai JiaoTong University is introduced,and the test results of the new multi-column TLP FOWT model test in the test tank are shown.The test results have great agreement with software simulation results.The results show that the deep water test tank of marine engineering of Shanghai JiaoTong University can be well developed as basin model test of FOWT.This paper supplies some guidance for the following model test and provides a theoretical basis for the development of the FOWT.
