METHOD FOR SEPARATING THE TERMS OF AN ELECTRICAL QUANTITY FROM MEASUREMENTS OF VARIOUS DEVICES Russian patent published in 2023 - IPC H02H3/38 

FIELD: electrical engineering; electric power industry.

SUBSTANCE: for each digital signal, the corresponding adaptive filter with a distributed structure is iteratively tuned to completely suppress the signal. The block diagram that implements the adaptive filter setting includes channels for generating signal components and a channel for generating a residual signal. To ensure the interconnectedness of the adaptive filter settings in the mentioned channels, canonical component filters are used, tuned at the previous iteration to suppress another digital signal, and the coefficients of these filters are changed by the converter, taking into account the sampling frequencies of its own and other digital signals.

EFFECT: increasing the speed of the method by artificially increasing the observation window by jointly tuning the adaptive filters of all digital signals.
