In this paper, three different methods of power resolution, namely that of Budeanu, Czarnecki and the IEEE Working Group, are compared for practical use. In order to study alternative compensation schemes for a large industrial plant, a steady-state harmonic penetration model has been developed on a Mathcad package. Three different interpretations are chosen with which to carry out this study, namely those of: Budeanu, the IEEE Working Group and Czamecki. The different interpretations are analyzed with the Mathcad model in a search for an optimal compensating topology. The paper begins with a general investigation into distortion power analysis, which is then extended to the above approaches. It concludes with a discussion in which the practical use of the different power analyzes is compared to each other in an industrial environment. The conclusions drawn are that the Budeanu method gives erroneous results in the presence of certain kinds of distortion and that the Czarnecki approach is complex and new to industrial users. Use of the IEEE Working Group approach is encouraged because it is merely an extension of the classic sinusoidal definitions that are already well understood
