波浪能是当今社会一种十分具有前景的清洁可再生能源，提高波浪能发电装置的转化效率尤为重要。针对波浪能发电装置只做垂荡运动的情况，本文建立基于微分方程的垂荡模型。以垂荡模型为基础，本文进一步计算波浪能发电装置的平均输出功率，并建立以波浪能发电装置平均输出功率最大为目标的最优阻尼系数模型。最后，本文通过多重搜索算法，遍历求解得到最大输出功率及对应的最优阻尼系数。
Nowadays wave energy as the clean and renewable energy resource has a promising future, so it is particularly significant to enhance the conversion efficiency of wave energy converter. Aiming at the situation that the wave energy converter only does vertical motion, this paper establishes a vertical oscillation model based on differential equation. In terms of this model, the paper further calculates the average output power of wave energy converter, and establishes an optimal damping coefficient model with the goal of the maximum average output power. Finally, the maximum output power and the corresponding optimal damping factor are obtained by traversing the solution through multiple search algorithms.
