Nonintrusive Electrical Loads Pattern Determination

Abstract The paper presents a possibility to determine the electrical patterns for the electrical loads through nonintrusive monitoring of their operating regimes. The electrical patterns are determined on the basis of the electrical parameters acquired for each load from the electrical network analysed. The determination of the electrical patterns is useful for the management of electrical energy consumption. The easiness of the nonintrusive monitoring technique is determined by the possibility of acquiring the electrical parameters from a single measurement point from the electrical network. From the electrical parameters acquired can be obtained information for electrical loads consumption recognition and their operating regimes, for certain time intervals, and it can be established the technical condition for each load.
