摘　　要：将基于液压传动的蓄能稳压方法应用于波浪能发电系统,可以较好地实现输出功率稳定。采用双行程浮力摆式波浪能捕获装置可以提高能量利用率。文中给出了此发电系统的数学模型,并在MATLAB/Simulink环境下对其进行了计算机仿真,然后在半物理试验平台上进行了仿真试验。计算机和半物理试验仿真的结果表明,该发电系统在蓄能器的缓冲作用及控制系统的调节作用下,能保证系统输出功率稳定,从而验证了采用液压传动方案的蓄能稳压浮力摆式波浪能发电系统的可行性。The stability of output power of wave power generation system can be achieved by wave power converter with pressure-maintaining storage methods based on hydraulic transmission system. The adoption of dual-stroke inverse pendulum wave power converter can improve the energy utilization rate. A mathematical model for this generation system is given, and a computer simulation is conducted by MATLAB/Simu]ink software. Moreover a semi-physical simulation is done in a semi- physical simulation platform. The computer and physical mode simulation results show that the output power of the system is stable under the action of accumulators and the control system, which validates the feasibility ot! the proposed generation system.
