Ugotavljanje nepooblaščenih odjemov v distribucijskih omrežjih z izračunom napetosti pri končnih odjemalcih

BRINOVEC, ROK (author), Gašperič, Samo (mentor)

V diplomskem delu smo podali možnost za odkrivanje kraj električne energije v distribucijskem omrežju s primerjavo izmerjenega in izračunanega napetostnega profila gospodinjskih odjemalcev. S sprotnim merjenjem napetostnega profila v transformatorskih postajah SN/NN in s povprečnim petnajstminutnim merjenjem moči gospodinjskih odjemalcev lahko izračunamo napetostne razmere v vozliščih distribucijskega omrežja, na osnovi katerih ocenimo, ali izmerjene vrednosti električne energije odstopajo od dejanskega odjema iz transformatorskih postaj SN/NN.

• Title: Detection of electric power theft in distribution networks by voltage calculation at end users

Abstract

In this dissertation we have introduced possible way to discover theft of electricity in a distribution system in comparison to measured and calculated voltage profile of household customers. With regular measurement of voltage profile in transformer stations (subtransmission / household voltage) and with measurement of power of household customers every 15-minutes it is possible to calculate voltage circumstances in nodes of distribution system. Based on such nodes we can evaluate if calculations of electricity differ from actual consumption from transformer stations.
