Method of Disturbances Interaction: Novel approach to assess responsibilities for steady state power quality disturbances among customers

Abstract

A new method to decompose currents in electrical circuits in order to analyze stationary power quality disturbances is presented in this paper. A set of reference conditions allows the definition of the desirable load behavior regarding power quality. The decomposition permits to analyze separately three stationary phenomena, waveform distortion, asymmetry and phase displacement. A discussion about the problem is responsibilities is presented as well.
