  • CONTROL OF A DFIG GRID SIDE CONVERTER
    Publication number: 20230420951
    Abstract: A method for controlling the reactive power exchange of a DFIG wind facility with the grid is provided. The method includes determining a grid side converter reactive power thermal limit value and determining the value of the required DFIG magnetizing reactive power to be consumed by the stator. Then setting dynamically the sharing of the reactive power between the stator and the GSC such that the GSC reactive power value is the difference between the reactive power demand of the DFIG wind facility and the magnetizing reactive power consumed by the stator. Afterwards operating the DFIG wind turbine facility such that the absolute value of GSC reactive power is adjusted to be below the grid side converter reactive power thermal limit value value. An arrangement and a wind turbine are also provided.
