The Study On Hydraulic Drive System Based On Comprehensive Development And Utilization Of Multi-energy At Sea

Because traditional energy is consuming, the energy crisis and environmental pollution are becoming more and more seriously. Ocean Energy as a sustainable energy has largely exploitation prospects with large density and low pollution. Therefore, integrated to develop offshore wind and wave energy has a positive meaning for the problem of energy shortage etc.This paper focuses on the design and analysis of hydraulic drive system of intermediate energy conversion device for multi-energy development.Firstly, there is a theoretical study and optimization design for hydraulic drive system of wave power generation, by optimizing hydraulic system of multi-float wave power generation to guide the number and size of float. In addition, calculate the parameters of hydraulic components of the wave power generation. By building mathematical models and using AMESIM software simulation analysis of the system. It emphatically analyzed the pressure of hydraulic system and the stability of motor speed.Next, this paper research the hydraulic drive system for the offshore wind energy, design a new wind power generation system. Calculate the parameters for hydraulic components of the wind generation, check the strength and stability of system. By using AMESIM and SIMULINK software, Focus on the control of the motor speed and stability of the system, finally there is a simulation experiment for wind power generation. Use Motor simulate the efficiency of entire hydraulic system under the action of the wind power.Finally, design a hydraulic system for multi-energy power generation, propose a synthesis scheme of the wave and wind power generation in hydraulic end. It elaborated the working principle of this system. And there is a model simulation study of the offshore wave energy and wind power generation by using software AMESIM. Optimizing the program based on the simulation results.
