  • Method for determining a droop response profile of a electrical machine connected to an electrical grid
    Patent number: 10790771
    Abstract: A method for determining a droop response profile of a rotating electrical machine supplying electricity to an electrical grid having a network frequency varying on either side of a nominal frequency, in which a measured value of the rotation speed of the rotating machine is retrieved, and the droop response parameters dependent on the measured speed value are defined. The droop response profile is a graph centered on the coordinates of an origin point between 99% and 101% of the measured speed and defined by at least two points of coordinates in the case of underspeed and/or by at least two points of coordinates in the case of overspeed, each of the points having for its abscissa a speed value as a percentage of the measured speed, and for the ordinates, a filtered speed value as a percentage of the measured speed modulated by at least one of the droop response parameters.
