Abstract

Gear boxes and direct-drive systems are commonly used in the transmission of large wind turbines. The components such as blades, rotor, gear box and the generator should be set up coaxially in the nacelle. Thus, the total weights of the nacelle increases with the size of the wind turbines. This research develops a hydrodynamic variable rotational speed transmission system combining with planetary gear-sets and the hydrodynamic transmission system for a 2MW wind turbine. The nonlinear dynamic models of hydrodynamic transmission system and planetary gear-sets are derived firstly. The dynamic simulation analysis for the feedback type hydrodynamic transmission system (FHDTS) with feedback planetary gear-sets is implemented using MATLAB/ SIMULINK. Finally, the closed-loop variable rotational speed control simulation combined with an intelligent controller can be achieved for evaluating the feasibility.
