摘要

Procedure and system for analyzing the quality of energy and 2S2PQ quality index for characterization of the signal at a point of the power supply. The procedure comprises: acquiring a voltage signal u (t), obtaining a preprocessed signal ue (t) adaptable to the processor, processing the signal to obtain a series of statistical features S1, S2, ..., SN characteristic of it, store said features, graphically represent the relative frequencies of said features associated with a temporal window of analysis Δ t selected by the user, compute the 2S2PQ index of power supply quality. The invention also comprises a system for statistical characterization at a point of supply and quality index, as well as a computer program incorporating code adapted to perform the steps of the procedure, when said program is executed on a computer or any other form of hardware programmable.
