METHOD FOR COMPUTER-AIDED ON-LINE MEASUREMENT OF CURRENT AND VOLTAGE UNBALANCE LEVEL Russian patent published in 2005 - IPC

Abstract RU 2249286 C1

FIELD: electrical and power engineering.

SUBSTANCE: proposed method intended for measuring current and voltage unbalance level and organizing on-line impact on them in three-phase power systems characterized in low quality of their power characteristics includes measurement of unbalance level with respect to reverse and zero sequence of both line and phase voltages and currents at frequency of each harmonic component. Frequency at which unbalance in analyzed characteristics occurs is found. Results obtained are used to generate control signal by correcting devices.

EFFECT: facilitated procedure.
