摘要

The proposed method for determining the parameters that characterize the operation mode of a single-phase main with voltage and current harmonic components consists in determining the instantaneous values of the main current and voltage at discrete instants, the instantaneous values of power consumed from the main, and the average power within the voltage period, determining the harmonic composition of the main current and voltage by the Fourier series coefficients, and determining the coefficients of distortion of the main current and voltage. To determine the parameters that characterize the operation mode of the main, the data for the frequencies of the harmonic components of the power consumed from the main are used. The proposed device for the realization of the method contains current and voltage instantaneous value transducers, an analog-to-digital converter, a computing unit, a data display, and a control unit.
