Abstract :
In this paper, the estimation of the disturbing frequencies injected by nonlinear load and the elimination of the parasitic harmonics in the electrical supply network is analyzed. The measurement in this paper is accompanied by colored additive noise. The noise is modeled by a filter AR of a finite order. The results of estimation and identification obtained are compared with Pizarenko, Prony, Music and SVD (singular value decomposition) techniques.
