Abstract

In this paper an efficient two-stage Newton type algorithm for power components estimation is presented. In the first algorithm stage the spectra and fundamental frequency of input currents and voltages are estimated. In the second stage the power components are calculated based on the results obtained in the first stage. By this, power components definitions according to the IEEE Standard 1459-2000 are used. In the algorithm the signal frequency was considered as an unknown parameter simultaneously estimated with signal spectrum. By this, the algorithm becomes insensitive to frequency changes. On the other hand, the signal model became non-linear, so the strategies of non-linear estimation were used. The algorithm performances are tested using computer simulated and laboratory tests.
