20.500.12556/DKUM-19260 ANALIZA IZGUB NA OSLABLJENEM PRENAPETOSTNEM ODVODNIKU ANALYSIS OF LOSES ON AGED SUTGE ARRESTER Diplomska naloga obravnava problematiko izgub električne energije na oslabljenem prenapetostnem odvodniku na transformatorski postaji Kot-Makej (0,95/0,4 kV) in neozemljenem izvoru. Omenjena transformatorska postaja se napaja iz razdelilne transformatorske postaje Ravne (RTP RAVNE) preko 20 kV daljnovoda Mežica in transformatorske postaje Kot (20/0,95/0,4 kV). Rešitev je predstavljena s programskim orodjem MATLAB/Simulink iz knjižnice PowerSystem, s katerim je izvedena simulacija pri oslabljenem prenapetostnem odvodniku. V nalogi je podana rešitev primera. This diploma thesis deals with the losses of electrical energy casued by the aged surge arrester. The discucced surge arrester is connected to the transformer substation Kot – Makej (0, 95/0, 4 kV where, the neutral point of the transformer’s secondary winding is ungrounded. The substation is supplied from the distribution transformer station Ravne (RTP Ravne) through 20 kV transmission line Mežica and transformer station Kot (20/0, 95/0, 4 kV). The analysis of the losses caused by the aged sourge arrester is performed with the model prepared in the program package MATLAB / Simulink using library PowerSystem. The diploma thesis proposes measures for reduction of energy losses that could be caused by the aged surge arresters.
