  • Publication number: 20220014023
    Abstract: The invention relates to a method for operating a power system of a wind turbine. The power system comprises first and second parallel connected DC-to-AC converters and at least one transformer, where each transformer comprises a primary section connected to a power line, and where the at least one transformer comprises first and second secondary sections connected to outputs of the respective first and second DC-to-AC converters. The method comprises providing a reactive correction reference, changing first and second reactive powers generated by the respective first and second DC-to-AC converters according to the reactive correction reference, so that one of the first and second reactive powers is increased while the other is decreased with amounts corresponding to the reactive correction reference so that the first and second reactive powers are unequal.

  • Patent number: 11156207
    Abstract: The present invention relates to operation of a wind turbine using a power storage unit, such as a rechargeable battery, to power a group of power consuming units during grid loss. The wind turbine comprises a number of power consuming units being grouped into at least a first group and a second group, a first electrical converter for connecting the generator to the electrical grid, and a second electrical converter for connecting the electrical generator to the power storage unit. Upon detecting an occurrence of the grid loss, the generator is operated to ensure sufficient power of the power storage unit to operate the first group of power consuming units.

  • Patent number: 8221076
    Abstract: A method of controlling at least one wind turbine blade during the stopping process of the rotor in a wind turbine system is disclosed. The method optimizes the control velocity of the process in response to one or more feedback values of the system and/or one or more feedback values from the surroundings of the system by altering the angular pitch velocity from 10°/sec during the initial stage of the stopping process to 5°/sec at the final stage of the stopping process. A control system and a wind turbine as well as use hereof are also disclosed.
