  • Wind turbine generator controller and method
    Patent number: 11177646
    Abstract: A wind turbine generator controller is described. The controller comprises switching circuitry, for selectively activating and deactivating one or more transducer circuits, and overcurrent detection circuitry, for detecting an overcurrent state in relation to one or more of the transducer circuits. The switching circuitry is responsive to the detection on an overcurrent state to selectively deactivate one or more of the transducer circuits.
    Type: Grant
    Filed: December 11, 2017
    Date of Patent: November 16, 2021
    Assignee: VESTAS WIND SYSTEMS A/S
    Inventors: Karl Axel Pétursson, Lars Rohrmann Andersen, Jesper Holm, Henrik Møller Ravn, David Steele, Arne Gormsen

  • Wind power plant with reduced losses
    Patent number: 10018180
    Abstract: The present invention relates to a method for controlling a wind power plant, the wind power plant comprising a plurality of wind turbine generators, each wind turbine generator comprising at least one power converter for providing active power and/or reactive power to an electrical grid, wherein the method is determining a required amount of reactive power provided by the plurality of wind turbine generators, and grouping the plurality of wind turbine generators into a first set of wind turbine generators and a second set of wind turbine generators based on a demand for reactive power; and supplying reactive power to the grid (20) from the first set of wind turbine generators and disconnecting the second set of wind turbine generators from the electrical grid (20) in response to a control demand, in order to minimize active power losses. The present invention also relates to a wind power plant arranged to perform the method.
