Abstract :
More and more wind power plants are built which use voltage source converters (VSC) to feed energy into grid. This paper compares two different control techniques and shows how virtual flux direct power control (VFDPC) reduces filtering requirements at the output of the converter and helps to save up to one quarter of converter losses. Furthermore the influence of a reduced, variable dc link voltage of the wind power plant itself and its converter control is discussed.
