Zvezna aproksimacija neenakomerno vzorčenih signalov
DENIS SODIN, Andrej Košir
Magistrsko delo
Oznake: neenakomerno vzorčenje;aproksimacija;interpolacija;prevzorčenje;zgornja frekvenčna meja;šum v podatkih;B-zlepek;
Magistrska naloga opisuje razvoj algoritma za aproksimacijo signala iz neenakomerno vzorčenih podatkov. Predlagana rešitev deluje na principu prevzorčenja merilnih podatkov in uporabe B-zlepkov za rekonstrukcijo signala. Pred realizacijo samega algoritma smo pregledali teorijo enakomernega in neena ...

Doktorska disertacija
Oznake: intelligent electronic device;phasor measurement unit;smart meter;IEEE C37.118 standard;power system measurements;electric power system;smart grid;frequency stability;under-frequency load shedding;short-circuit faults;fault localization;fault classification;
For some time now, we have been observing clear trends of climate change all over the world that are disturbing the delicate balance of the ecosystem to a not inconsiderable degree. While some tend to attribute these phenomena to processes on the scale of a geological era, i.e., to enormous cyclical ...

Precise PMU-based localization and classification of short-circuit faults in power distribution systems
Denis Sodin, Miha Smolnikar, Urban Rudež, Andrej Čampa
Izvirni znanstveni članek
Oznake: telekomunikacije;natančna lokalizacija;PMU poglaga;napake kratkega stika;
Knowing the exact location of a short-circuit fault in a power distribution system (PDS) is essential for rapid restoration of service to customers and has a direct impact on the operational costs and reliability of the system. In this paper a phasor measurement unit (PMU) based method for fault loc ...

It is widely recognized that in the transition from conventional electrical power systems (EPSs) towards smart grids, electrical voltage frequency will be greatly affected. This is why this research is extremely valuable, especially since rate-of-change-of-frequency (RoCoF) is often considered as a ...

Advanced edge-cloud computing framework for automated PMU-based fault localization in distribution networks
Denis Sodin, Urban Rudež, Marko Mihelin, Miha Smolnikar, Andrej Čampa
Izvirni znanstveni članek
Oznake: fault detection;fault localization;edge-cloud framework;distribution network;smart grid;
The detection and localization of faults plays a huge role in every electric power system, be it a transmission network (TN) or a distribution network (DN), as it ensures quick power restoration and thus enhances the system’s reliability and availability. In this paper, a framework that supports pha ...
