Colored Petri net model of electrical networks for diagnostic purposes

摘要

A simple and effective colored Petri net (CPN) model is proposed in this paper for a special type of electrical networks that describe local transformer areas, in order to detect and localize illegal loads that may be present. The model is decomposed to characteristic structural elements called feeders with one or two sources the computation of which can be performed independently and in parallel. The CPN model allows to handle the interval-type uncertainties in the model in a transparent and effective way.
