METHOD FOR COMPUTER-AIDED ACTIVE CHECK OF CURRENT AND VOLTAGE PULSES Russian patent published in 2005 - IPC

Abstract RU 2252471 C1

FIELD: computer-based systems for electrical energy quality control.

SUBSTANCE: fundamental-frequency harmonic components are separated from set of digital values of current and voltage. Results of comparison of actual instant current and voltage values with instant values of fundamental-frequency harmonic components provide for finding out if pulses are available and also if they comply with their specified values. If current and voltage pulses do not comply with specified values, signal is generated to control correcting device designed to reduce amplitude and length of current and voltage pulses.

EFFECT: Facilitated procedure.

1 cl, 5 dwg
