Abstract: The impact of wind generation on the electrical system should be assessed to figure out potential hazards to system operation and deterioration of power quality indices. In this paper signal processing algorithms has been applied to analyse switching transients within wind generation units. Nonlinear regression method and Prony model were applied to determine transients’ parameters for various operation modes of the wind generator. Both methods delivered quite satisfactory results, but the regression method was prone to local minima.
