Abstract

Zaradi priključevanja velikega števila razpršenih virov v distribucijska omrežja in povečanja obremenitve, postaja ohranjanje napetostnega profila v mejah, določenih s standardom, bolj zahtevno. Odjemalcem je treba zagotoviti stabilno in zanesljivo neprekinjeno oskrbo z električno energijo. Posledično se pojavljajo različne tehnologije in algoritmi za zagotavljanje napetostnega profila. Eden od njih je predstavljen v tem magistrskem delu. V magistrskem delu je izvedena analiza možnosti zagotavljanja napetostnega profila z uporabo transformatorja s spremenljivo prestavo, nastavljivo pod obremenitvijo, v omrežje RTP Murska Sobota. Napetosti vozlišč in toke vej smo izračunali z uporabo metode BFS (Backward – Forward Sweep), zaradi dobre konvergence in možnosti uporabe v radialnih distribucijskih omrežjih. Opisan je postopek priprave vhodnih podatkov, potrebnih za izračun z metodo BFS in teoretično ozadje delovanja transformatorja s spremenljivo prestavo.

Secondary title:	Analysis of the impact of on-load tap changer equipped transformer on the voltage profile in substation Murska Sobota
Secondary abstract:	Due to the connection of a large number of distributed energy resources to distribution networks and the increase in load, maintaining the voltage profile within the limits set by the standard is becoming more demanding. It is necessary to provide customers with a stable and reliable continuous supply of electricity. As a result, various technologies and algorithms for adjusting the voltage profile are emerging. One of them is presented in this master's thesis. The master's thesis analyzes the possibility to control voltage profile using an on-load tap changer equipped transformer in the distribution network connected to the substation Murska Sobota. Node voltages and branch currents were calculated using the BFS (Backward - Forward Sweep) method, due to good convergence and the possibility of use in radial distribution networks. The process of preparing the input data required for calculation with the BFS method and the theoretical background of the operation of an on-load tap changer equipped transformer are described.
