Abstract

The method for measurement of nonsinusoidal factor of phase and line voltages using the converter of single-phase voltage in three-phase symmetric system of is developed. Such system of voltages is connected on an input of symmetric components filters (SCF) connected in cascade of negative and positive phase-sequence voltages and matching networks of type US1-3. Simulation and study of dynamic properties of the devices that implement the proposed method, showed that at fast connection of positive phase-sequence voltages the transient decays for a time less than one and a half period of voltage of a fundamental frequency. References 11, figures 2, table 1.

Key words: single-phase voltage, nonsinusoidality, quality of the electric power, symmetric components filter.
