In this paper, the basic independent component analysis (ICA) model is used to suppress white noise for partial discharge (PD) signals. The mathematical model of ICA is described, and its application in simulation PD signals and PD pulse current signals at HVDC are investigated. The results manifest that the white noise can be effectively suppressed with keeping the most important information of PD signals.

W artykule przedstawiono model niezależnej analizy składowych użyty do tłumienia białego szumu towarzyszącemu sygnałowi wyładowania niezupełnego PD. Opisano model matematyczny i jego zastosowanie w symulacji sygnału PD. Wyniki wskazują, że biały szum może być efektywnie tłumiony przy utrzymaniu wszystkich ważnych informacji sygnału PD.
