Detection and identification of Potentially Disturbing Loads and consumers: Methodology and case study

This work shows an algorithm developed from a knowledge base, which consists of four lists inter-relatable and multiple criteria methodology. From an expert system, it is possible to calculate the index C2P that can be used in an “a priori” analysis to determine Potentially Disturbing Loads or, using a set of electrical data measurements, perform an “a posteriori” analysis in order to assign a comparative index for Potentially Disturbing Consumers. Besides the knowledge base implemented, these analysis also include the susceptibility curves to voltage variations ITIC and SEMI and proposed indices of Brazilian (PRODIST) and global (IEEE and IEC) references. The methodology was applied, as a case study, in an industrial consumer in plastics domain of Southern Brazil.
