20.500.12556/DKUM-75082 Primerjava analize električnega omrežja z metodo BFS in programskim orodjem OpenDSS magistrsko delo The comparison of electricity network analysis using the BFS method and the OpenDSS program tool Magistrska naloga obravnava načine ovrednotenja obratovalnih stanj v električnem distribucijskem omrežju. Primerjani sta izvedbi izračuna pretokov energije z metodo »Backward Forward Sweep« (BFS) v programskem okolju Matlab in odprtokodnega programskega orodja OpenDSS (DSS). Primerjane so izračunane vrednosti napetosti vozlišča, izgube omrežja in čas izračuna. Primerjava je izvedena na različnih modelih testnih in realnih omrežij radialne in zazankane konfiguracije z in brez uporabe transformatorjev. Testirani so vplivi različnih modelov bremen in različnih lastnosti vodnikov, ki se kažejo v razmerju X/R parametru. Na koncu je izveden primer optimizacije z uporabo diferenčne evolucije in orodja OpenDSS. The master's thesis deals with methods for evaluating operating conditions in electricity distribution networks. The comparison of lower flow calculation based on the Backward Forward Sweep (BFS) method implemented in Matlab with the ones based on the open-source tool OpenDSS (DSS) has been performed. The calculated values of voltages at individual node, system losses and calculation times are compared. The comparison is performed for different test and real networks with radial and mash configurations, considering transformers and without them. The effects of different load models and different conductors' characteristics, shown in different ratio X/R, on results obtained by the BFS method and the OpenDSS tool have been evaluated. Finally, an optimization is performed using Differential Evolution and OpenDSS. električna omrežja izračun pretokov energije orodje OpenDSS metoda BFS Keywords: electricity networks load flow calculation OpenDSS tool BFS method true true false [D.
