Wind Generator Transients' Computation using Prony Method

Artikel i vetenskaplig tidskrift, 2007

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 indicia. In this paper signal processing algorithms has been applied to analyze switching transients within wind generation units. A Prony model of the signal and a nonlinear regression method 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.
