摘要： A wind turbine is provided. The wind turbine comprises a generator, a power converter for converting at least a portion of electrical power generated by the generator, an energy dissipating unit and a controller. The power converter comprises a generator-side converter, a grid-side converter and a DC (direct current) link there between. The energy dissipating unit is operatively coupled to the DC-link. The controller is adapted to activate the energy dissipating unit to dissipate energy from the DC-link in response to a shutdown request.

摘要： The invention relates to wind turbines, particularly to controlling reactive power exchange between a power grid and a wind power plant. The wind power plant has a plurality of wind turbine generators each having a corresponding power converter with a converter controller. Further, the wind power plant has a power plant transformer with an on load tap changer coupled between the wind power plant and the power grid. The power plant controller is regulating the on load tap changer and is generating reactive component setpoints for the wind turbine generators, when determining a need for production of short-term reactive power due to a sudden change in reactive power measured at the point of common coupling.

摘要： The invention relates to a method for controlling power generation of a VSM wind turbine. The wind turbine comprises a machine side converter (203), a line side converter (204), a DC link (205), and an electric storage device (241) electrically connected to the DC link. The method comprises determining a first power control signal (PMSC) to the machine side converter (203), determining a second power control signal (PVSM) for controlling a desired output power (Pgrid) of the line side converter (204) based on a storage device voltage error (Vbat_e), and a power production reference (Ppro), and determining a charging current reference (Ibat_ref) for controlling charging and discharging of the electric storage device (241) based on a DC-link voltage error (Vdc_e).

摘要： A method is provided of protecting a wind turbine with a doubly-fed induction generator (DFIG) against a sub-synchronous resonance (SSR) event acting on the wind turbine. A plurality of power-output values or current-output values is measured over a given period of time that corresponds to a measurement cycle. It is determined whether power-output values or current-output-values measured in the at-least-one measurement cycle are indicative of an SSR-event critical for further operation of the wind turbine. The wind turbine is shut down if the measured power-output values or current-output values are indeed indicative of an SSR- event critical for operation of the wind turbine.
