Abstract

A method of describing the power properties of circuits with nonsinusoidal waveforms of voltage and current is discussed. The method is based on the source current decomposition into orthogonal components dependent on different power phenomena. The active power transmission, current shift, the load conductance variance with frequency, nonlinearity, and time-variance of the load parameters, as well as symmetry of three-phase loads, can be considered as phenomena that contribute to the source current value as separate current components. The author suggests a modification of the decomposition discussed, to a form that may be more appropriate for describing the power flow in circuits with rotating loads
