摘　　要：点吸收式是目前世界上发展较多、转换效率较高的一种波浪能利用技术,介绍我国自主研发的一台10 kW漂浮点吸收波浪能直线发电装置。该装置主要由4 m直径蝶形振荡浮子、6 m直径水下阻尼板、1 t重直线发电机组成,整个装置漂浮在海面上,是一个钢结构体。装置外形为煤油灯形,采用共振聚波和阻尼匹配技术提高装置的转换效率,有效发电时间不受来波方向和潮位的影响,针对构成装置的不同材料采用不同的防腐技术提高装置的整体抗海水腐蚀能力,采用下潜方式躲避台风打击,采用蓄能技术提高锚泊系统抗走锚和断链能力。直线发电机是一个圆筒型结构体,具有较高的转换效率和防海水腐蚀能力。发电装置进行了实海况试验,为后续的研究工作提供了相关经验。The point absorber is a wave energy conversion technology, which has high conversion efficiency and has developed rapidly in the world. The 10 kW floating direct drive wave energy device based on the point absorber technology developed in China was introduced. The device consists of a oscillating buoy with a diameter of 4 m, a submerged plate with a diameter of 6 m and a linear generator with 1 ton of weight, which makes up of steel and floats in the sea. The device has a shape of a kerosene lamp. The resonance technique and the damping matching skill were adopted to improve the conversion efficiency of the device. The effective generating time was free of wave direction and the tide. Different anti-corrosion methods and process were adopted for different materials for anticorrosion. The device can submerge to escape large waves during a typhoon. The storing energy technique was used to improve the anchoring system to keep the anchor chain out of the anchor point and prevent the breaking. The line generator is a type of cylinder with the ability of higher efficiency and anti-corrosion. The device has been deployed for sea trial.
