INSTANTANEOUS POWER SIGNAL ANALYSIS AND ITS COMPONENTS IN NONSINE CIRCUITS IN ELECTRIСAL PROBLEM SOLVING

A common approach to analysis and synthesis of the instantaneous power and voltage signal for non-sinusoidal circuits, which allows along with a quantitative evaluation make a qualitative analysis of the mechanism of formation of their spectra, as opposed to previously known, is considered. The problem of the spectrum transformation of a periodic non-sinusoidal signal in case of the coordinate system shift is considered. Approaches are actual in solving energy balance equations in problems of parametric identification of electric machines with regard to their non-linear nature and in synthesis of voltage signal for a given harmonic content of the instantaneous power in control quality of electrical energy conversion. The resulting mathematical relations are presented in conventional terms of signal theory and matrix algebra. On practice, this allows to synthesize high-speed computing procedures and it is important in design of quality control systems of energy conversion in real time.
