METHOD AND SYSTEM EMPLOYING FINITE STATE MACHINE MODELING TO IDENTIFY ONE OF A PLURALITY OF DIFFERENT ELECTRIC LOAD TYPES

摘要

A system is for a plurality of different electric load types. The system includes a plurality of sensors (V,I) structured to sense a voltage signal and a current signal for each of the different electric loads; and a processor (21). The processor acquires (22) a voltage and current waveform from the sensors for a corresponding one of the different electric load types; calculates (24) a power or current RMS profile of the waveform; quantizes (26) the power or current RMS profile into a set of quantized state-values; evaluates (28) a state-duration for each of the quantized state-values; evaluates (30) a plurality of state-types based on the power or current RMS profile and the quantized state-values; generates (32) a state-sequence that describes a corresponding finite state machine model of a generalized load start-up or transient profile for the corresponding electric load type; and identifies the corresponding electric load type.
