METHOD OF EXPRESS-EVALUATION OF THE TOTAL COEFFICIENTS OF HARMONIC COMPONENTS IN ELECTRIC NETWORKS

Abstract

The method of estimating the total coefficient of harmonic components. The method does not require the decomposition of a periodic signal into higher harmonics. The formula for calculating the total coefficient of harmonic components for discrete measurements of the electrical network voltage does not require the use of Fourier transforms to extract higher harmonics. The method makes it possible to estimate the coefficient of harmonic components both in the analysis of the conformity of voltage to the energy quality standards and in the estimation of the emission of higher harmonics of current into the network from nonlinear consumers.
