摘　　要：为提高现有波浪发电系统的稳定性和效率,提出了一种新型的浮子式波浪发电系统,介绍了其具体结构和特点.同时,采用解析法详细分析了波浪能转换装置(WEC)所受的重力、浮力、系链拉力等情况.根据天津波浪特性,对所提出的波浪发电装置进行了仿真分析.分析结果表明,所设计的波浪能转换装置具有较好的单向周期性稳定输出转矩特性,且其效率较传统的浮子式WEC提高了10%左右.In order to improve the stability and efficiency of wave power generation system, a novel float-type wave power generation system was presented in this paper. The structure and characteristics of the system were introduced. Furthermore, the gravity, the buoyancy and the mooring force, which acted on the wave energy converter （WEC）, are analyzed by the analytic method. Then, corresponding simulation was done with the wave data in Tianjin. The results show that the proposed WEC owns better single-direction periodical output torque and its efficiency is increased by about 10% compared with the traditional float-type WECs.
