EVALUATION METHOD OF CONSUMER INFLUENCE ON VOLTAGE DISTORTION AT POINT OF COMMON COUPLING Russian patent published in 2017 - IPC G01R21/00 

FIELD: electricity.

SUBSTANCE: influence evaluation of the k consumer on the voltage distortion at the point of common coupling is carried out by determining the parameters of the autonomous voltage distortion of the k consumer and the influence coefficient on the voltage distortion of the k consumer and comparing these parameters with the acceptable ones. The evaluation is performed on a real time basis using the values of the voltage vectors on the bus leads at the particular node of the network and the current at the coupling of the k consumer smoothed, measured with a given discreteness, smoothed by the Savitzky-Golay filter with subsequent screening of pairs of successive measurements with small changes in voltage and current.

EFFECT: ensuring a reliable qualitative and quantitative influence evaluation of consumers on the voltage distortion on a real time basis, which includes increasing of the accuracy of determining the parameters of consumer loads.
