Abstract:

In this paper,the working principle and advantages of hydraulic energy- storage wave energy converter(WEC) are analyzed,and four basic characteristics of the power generation system with hydraulic energy- storageWEC are deduced according to the mathematical equations of the hydraulic motor and the permanent magnet synchro-nous generator.Then,the effects of accumulator pressure and generator load on the motor and the generator speed,the generator voltage and the generator power are analyzed.Moreover,two working modes of the hydraulic powergeneration system,namely the constant resistance mode and the constant speed mode,are taken into consideration,and a corresponding simulation model is established based on Matlab/Simulink for the power generation system.Finally,some simulation experiments are carried out,and the results verify the correctness of the deduced charac-teristics of the hydraulic power generation system.

Key words: wave energy, power generation assembly, hydraulic energy- storage power generation system, Matlab;simulation analysis
