Abstract

The invention discloses a non-invasive load monitoring method, device and equipment as well as a storage medium. The method comprises the following steps: selecting a plurality of different load conditions, and acquiring characteristic values of the load conditions, wherein the characteristic values comprise steady state fundamental wave active power in the load conditions and amplitude of an oddharmonic of a steady state harmonic current; establishing a load characteristic database; and selecting a globally optimal extreme value and a globally optimal position of the characteristic values byutilizing a binary particle swarm optimization algorithm, and constructing a load condition recognition algorithm. The method disclosed by the invention performs active power estimation by utilizingthe load characteristic database and the load condition recognition algorithm, outputs a load structure corresponding to the current load condition, utilizes the steady state fundamental wave active power and the amplitude of the odd harmonic of the steady state harmonic current as the characteristic values, can rapidly recognize different load types from the total current and reduces calculated amount of a system during load recognition.
