Abstract  

A wave power generating device based on hydraulic transmission was designed in order to make the system have advantages of transmission smooth and speed convenience. The buoys, wave plates and groups of hydraulic cylinder could obtain wave energy. Hydraulic system pressure stability and generator power output stability could be separately realized by accumulator and adjusting the displacement of the volume adjustable hydraulic motor. A mathematical model for the wave power generating system was given and a computer simulation was conducted by AMESim software. An experiment of wave power generating platform was conducted in actual sea conditions. The computer simulation and experimental results show that the system can ensure the hydraulic system pressure stability and the generator power output stability, which validates the rationality of the oscillating buoy wave power generating system based on hydraulic transmission.

基于液压传动的振荡浮子式波浪发电系统设计

为了使波浪发电系统具有传动平稳、调速方便等优点,设计基于液压传动的振荡浮子式波浪能发电装置.该装置通过浮子、波浪板与群组油缸技术获取波浪能量；使用蓄能稳压的方法保证液压系统压力稳定；通过调节变量液压马达的排量达到发电机电量输出稳定.给出该发电系统的数学模型,应用AMESim软件对液压发电系统进行仿真,通过平台实海况试验进行验证.仿真结果和试验结果表明,该发电系统不仅可以保证液压系统压力稳定,还可以达到发电机输出功率稳定,验证了采用液压传动方法的振荡浮子式波浪发电系统设计的合理性.
