Abstract: Wind power generation system, equipped with the speed regulating differential mechanism (SRDM), is able to be friendly connected to the power grid without the need for partially- or fully-rated converters. The novel alternative transmission schemes have shown promising potential in addressing several issues present in existing variable speed constant frequency grid-connected wind turbines(WTs), such as huge reactive power consumption, weak low voltage ride through ability as well as unsatisfactory output power quality and dynamic stability. To further improve the operational performance of SDRM-based WT and eliminate the adverse effects caused by the high-cost sensors, high-power speed regulating motor and corresponding expensive control units, a novel WT transmission scheme equipped with a self-stabilizing SRDM is proposed. Taking the self-stabilizing SRDM-based WT as the research object, its kinematic principles and transmission characteristics are thoroughly studied, on the basis of determining the structural configuration of the proposed transmission system. A dedicated semi-physical experimental platform is constructed, and its key inertia and damping parameters are calculated by using the ridge regression algorithm. Finally, simulation and experimental case studies are conducted under varying wind speeds, through which the feasibility and superiority of the proposed self-stabilizing SRDM-based WT are verified.
