With the increasing shortage of traditional energy and the aggravation of environmental pollution,clean and renewable energy is more and more welcomed by people,developing and utilizing ocean energy for power supply has gradually become a trend,and will play an important role in the future society.Wave energy,as a kind of clean energy,has been gradually coming into people's sight.With the majority of scholars of the wave energy power generation continuous research and thorough,all kinds of wave energy power generation device are more and more,and they are faced with the problems at the same time also become more and more complex.One of the most significant problem of waves is randomness and unpredictability,causing the instability of wave energy power generation device performance,a series of problems such as unreasonable design.At present,there are three methods to deal with the randomness and unpredictability of waves:model test,theoretical or numerical method calculation and field observation of sea test.In this paper,model tests,theoretical or numerical methods are combined to build a simulation test platform for wave energy power generation,which can not only more realistically simulate the actual situation at sea,but also provide guidance for ensuring reasonable design of wave energy power generation devices and making full use of wave energy power generation.Therefore,the establishment of a simulation test platform is of great practical significance for the study of wave energy generationThis paper covers the following research work(1)Aiming at the randomness and unpredictability of waves,a simulation test platform for wave energy generation is proposed and designed in this paper.According to the principle of oscillating float wave energy generating device,the overall mechanical structure scheme and hydraulic system scheme of wave energy generating simulation test platform is proposed.Then,the power generation circuit and wave simulation circuit are analyzed in detail.In order to ensure the reasonable design of the whole test platform,the components of power generation circuit and wave simulation circuit are selected and debugged respectively,and the components are checked by numerical calculation.(2)Based on the overall design scheme of the wave energy generation simulation test bed,the structure and signal flow chart of the wave simulation system are drawn.According to the working mode of each component on the simulation test platform,the mathematical model of each component is established,and the corresponding technical parameters are calculated.Then,the transfer function of the hydraulic servo system of the wave simulation circuit is established,and the stability of the wave simulation circuit is analyzed.Finally,in order to ensure a more realistic simulation of wave conditions on the wave power generation simulation test bed,PID control is adopted and its parameters are set by particle swarm optimization algorithm.(3)In order to ensure that the simulation test platform can accurately simulate wave energy generation,this paper adopted AMESim and Matlab/Simulink to build the electromechanical joint simulation model of the simulation test platform,and preliminarily verified the accuracy of the simulation model to fitStudy of wave energy power generation simulation experiment platform is a meaningful and complicated work,which about simulation test platform power circuit and the mathematical model of wave simulation circuit,the particle swarm algorithm setting of PID parameters and simulation test platform of electrical and mechanical joint simulation model for the future development of wave energy power generation has a certain guiding significance.
