Modelling and control of dual generator type wind turbine (DGWT)

This paper deals with the dynamic model and controller for dual generator type wind turbine (DGWT). DGWT is kept distinct from typical horizontal axis wind turbine (HAWT) by following structure, four bevel gears are equipped in the nacelle, the parallel generators installed on the ground like a vertical axis wind turbine (VAWT). This structure was already proposed in previous research which shows the advantages for transmission line problem or minimize the converter size, but the dynamic model was not addressed in detail. In this paper, we derive the the dynamic model of DGWT from Euler-Lagrange equation. Moreover, simulation and experimental results are also included to validate the performance of DGWT.
