TL;DR: The proposed undisturbed switching strategy reduces output power fluctuations and mechanical loads significantly, which is also friendly to power grid and wind turbine devices.
Abstract: This paper proposes a novel undisturbed switching strategy based on gain self-regulation for wind turbine generation system (WTGS) to restrain extra power fluctuations and mechanical loads caused during the controller switching process between full-load region and partial-load region. The switching characteristics near rated wind speed is firstly analyzed, and theoretical foundation of gain regulation is discussed. Then the gain self-regulation method based on Fourier transform is presented to optimize the switching performance. The simulation results based on FAST reveal that, the proposed switching strategy reduces output power fluctuations and mechanical loads significantly, which is also friendly to power grid and wind turbine devices.
