摘要
本文提出一种波浪能转换装置来产生电能,为水下装置提供持续的能源供给,建立了其液压式PTO的数学模型。为提高装置对海况的适应性和能量俘获效率,分析了其实现变阻尼控制的方法,对不同海况下和波浪周期内的变阻尼控制策略进行了数值仿真。
A wave energy conversion device is proposed to provide constant electric power for underwater equipment. A mathematical model of hydraulic PTO for wave energy conversion device is established. In order to improve the adaptability of the de vice to the sea state and the energy trapping efficiency, the method of realizing variable damping control is analyzed. The numerical simulation of variable damping control strategy under different sea conditions and wave periods is presented.
