Diepeveen, N.F.B. Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2013-02-04 Abstract In the pursuit of making wind energy technology more economically attractive, the application of fluid power technology for the transmission of wind energy is being developed by several parties all over the world. This paper presents a dynamic model of a fluid power transmission for variable speed wind turbines and shows a parametric study on the dynamic behaviour below rated wind speed. A pressure control strategy is proposed to achieve a variable speed operation. The rotor of the NREL 5 MW reference turbine is used to perform time domain simulations. Different values of the hydraulic line length, transmission efficiency and rotor mass moment of inertia are considered for the same wind conditions. The results show that the amount of oil in the system has a relatively large influence in pressure transients and controllability. Lowering the volumetric efficiency of the hydraulic motor leads to more damping of this pressure fluctuation, however its influence is minor and unlikely to be advantageous when compared to the power loss. A higher rotor mass moment of inertia implies a slower but smoother response of the system.
