摘要
通过建立Matlab/Simulink仿真模型求解Cummins方程,计算摆式波能发电装置在不规则波中的瞬时功率和平均功率,同时考虑线性和非线性动力摄取系统的影响。线性假设下的数值结果与试验数据的对比验证目前数值模型的精度。进一步使用摆板-液压系统联合仿真模型研究液压式转换装置中不同影响因素对发电功率的影响,发现液压系统中活塞面积存在最优值使得装置在给定海况下的发电量最大化。
The instantaneous power and average power of the flap-type wave energy converter in irregular waves were calculated in MATLAB/Simulink to solve the Cummins equation. The effects of linear and nonlinear power intake systems were considered in analysis.The comparison between the numerical results under the linear assumption and the experimental data verifies the accuracy of the present numerical model. The influence of different hydraulic parameters on the electrical generation was studied using flap-hydraulic model. It can be concluded that there is optimum value of piston area to achieve maximum electrical power in specified wave condition.
