摘要：

针对波浪能发电效率低的问题, 建立由波浪输入至马达输出的系统数学模型, 采用理论建模和仿真分析相结合的方式确定影响系统发电功率的关键参数, 为提高装置发电效率的液压能量转换系统恒转速控制策略的研究提供理论指导。波浪能发电的液压蓄能式波浪能发电系统主要由3部分组成, 建立系统各元件的运动方程及能量方程, 寻找元件间的连接参数建立系统数学模型, 通过理论分析系统功率方程定性地确定系统工作特性及关键参数。为验证理论分析结果的准确性, 借助AMEsim仿真平台完成系统设计及仿真验证。结果表明, 马达输出功率主要受波浪波高、周期、比例流量阀流通面积及马达排量的影响, 最高影响阶次分别为1次方、4次方、4次方和2次方。仿真验证还证明蓄能器预充气压力几乎不会对马达输出功率产生影响。

Abstract:

To improve the efficiency of wave power generation technology, a mathematical model of the system from wave input to motor output was established. The key parameters that affected the system′s power generation capacity were analyzed by using theoretical modeling and simulating, so as to provide theoretical guidance for the research of the constant speed control strategy of the hydraulic energy conversion system. The hydraulic energy storage system of wave energy generation was composed of 3 parts. The mathematical model of the system was established by analyzing each component′s motion equation and energy equation, and finding the connection parameters between the two components. The key parameters and characteristics of the system were determined qualitatively by analyzing the system′s power equation. To confirm the accuracy of theoretical analysis, the AMEsim simulation platform was used to design and imitate the system. The results showed that the motor′s output power was affected by the height of the wave, period, flow area of the proportional flow valve and the motor displacement. The highest order of the influence was 1, 4, 4 and 2, respectively. The results also verified that the precharging pressure of the accumulator had little influence on the motor′s output power.

Key words: wave energy conversion, hydraulic energy storage, analytical model, simulation platform, operating parameter of component
