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.
