ESTIMATION ENERGY CONVERSATION PROCESSES WITH USING INSTANTANEOUS POWER COMPONENTS

The approach to the decomposition of the instantaneous power of polyharmonic signals based on the analysis of the processes of frequency conversion orthogonal components of voltage and current has been refined. It has been shown that the order of the harmonics of power is the sum and difference frequencies of the harmonic components of the original signals. The importance of energy conversation processes of the first and second order in the formation of the components of instantaneous power of non-sinusoidal signals has been noted. A mathematical apparatus and diagrams of the canonical form, and the non-canonical psevdocanonical component of the instantaneous power at different harmonic content of voltage and current has been proposed. The amplification of the alternating component of the power due to the coincidence frequency of canonical and psevdocanonical component has been proved. The indicators of energy processes based on the effective values of the instantaneous power and its components has been proposed. It has been shown that the energy mode affects not only the amplitude values of voltage and current harmonics, but the combination of frequencies that form the harmonic spectrum of the original signal.
