Modeling of hydraulic wind power transfers

The energy of wind can be transferred to the generators by using a gearbox or through an intermediate medium such as hydraulic fluids. In this method, a high-pressure hydraulic system is utilized to transfer the energy produced from a wind turbine to a central generator. In this paper, a gearless hydraulic wind energy transfer system is introduced and the dynamic model of the system is obtained. A pressure loss model is introduced to address transmission efficiency. The dynamic model is verified with a detailed model created by using the SimHydraulics toolbox of MATLAB. The comparison of the simulation results demonstrated successful validation of the mathematical model.
