Expansion of Set of Power Efficiency Factors of Power Electronics Installations

Based on the author’s direct calculation methods of power-producing processes, new quality indicators of nonsinusoidal voltages and currents in the form of integral and differential coefficients of harmonics of voltage and current have been obtained. The advisability of introducing them into the standards for the quality of the power network voltage and the consumption current, as well as also into the method for calculating of the partial participation of the consumer and the power supply system in the change in the overall quality of the electric energy has been shown.
