Analiza zaznavanja omrežnih dogodkov s pametnim števcem

Neubauer, Rok (author), Rudež, Urban (mentor)

V diplomski nalogi smo preizkusili pametni števec IE.7-TT1-H11 podjetja Iskraemeco s simulatorjem RTDS, ki omogoča simulacijo napetostnih dogodkov v realnem času. Cilj naloge je bil preučiti delovanje števca pri različnih napetostnih dogodkih in oceniti njegovo natančnost pri zaznavanju napetostnih odstopanj, kot so padci napetosti, prenapetosti in izpadi napajanja. Števec je bil testiran v različnih scenarijih, vključno s kratkimi stiki na posameznih fazah in vseh fazah hkrati. Rezultati so pokazali, da števec zanesljivo zaznava napetostne dogodke in sproži ustrezne alarme ter pravilno beleži dogodke, kar potrjuje njegovo uporabnost za izboljšanje stabilnosti elektroenergetskih omrežij. Preizkusi so potrdili, da je števec natančen in zanesljiv ter sposoben zaznavati napetostne dogodke v kompleksnih večfaznih scenarijih, kar je ključno za učinkovito upravljanje napajalnih omrežij.

Abstract

In this thesis, we tested the smart meter IE.7-TT1-H11 from Iskraemeco using the RTDS simulator, which enables real-time simulation of voltage events. The aim of the thesis was to examine the performance of the meter under different voltage events and assess its accuracy in detecting voltage deviations, such as voltage dips, swells, and power outages. The meter was tested across various scenarios, including short circuits on individual phases and on all phases simultaneously. The results showed that the meter reliably detects voltage events, triggers appropriate alarms, and correctly records events, confirming its effectiveness in enhancing the stability of power systems. The tests confirmed that the meter is accurate and reliable and capable of detecting voltage events in complex multi-phase scenarios, which is crucial for the efficient management of electrical power systems.
