基于模型试验法,研究PTO阻尼力、浮子底部形状对波能装置-浮式防波堤集成系统发电与防波性能的影响,并将单浮体型集成系统与双浮体型混合系统进行对比,分析防波堤对波能浮子发电性能的影响。结果表明：三角加挡板形浮子的发电与防波性能均优于方箱形和三角形浮子;相比于单浮体型集成系统,双浮体型混合系统的发电与防波性能显著提高,但当发生窄缝共振时,具有三角加挡板形浮子的双浮体型混合系统的发电性能显著降低。
Abstract
Based on the model test method, the influence of the power take-off PTO damping force and the bottom shape of the wave energy converter WEC on the power extraction and wave attenuation performance of the WEC-floating breakwater hybrid system is researched. The performance of the single-body WEC-breakwater integrated system is compared with those of the dual-body hybrid system to analyze the influence of the breakwater on the wave energy extraction performance of the WEC. Results show that the triangle-baffle-shaped bottom has superior power performance compared with rectangular and triangle bottoms. Compared with the single-body integrated system, the power generation and wave attenuation performance of the dual-body system improves compared with the single-body integrated system are significantly improved. However, while narrow-gap resonance occurs, the power generation performance of the dual-body integrated system with the triangle-baffle decreases significanty.
