Abstract
U radu su objašnjeni principi gašenja istosmjerne i izmjenične struje, naveden je postupak gašenja električnog luka prilikom prekidanja izmjenične struje usporedbom idealnog i realnog prekidača. Objašnjeni su pojmovi sabirnički kratki spoj i bliski kratki spoj s navedenim primjerom. Povratni napon kao temelj analize definiran je sa pripadajućim sastavnim elementima. Opisano je postrojenje 400 kV koje je predmet analize u stvarnom pogonskom stanju sa... More stvarnim podacima. Detaljno je prikazano modeliranje postrojenja 400 kV pomoću programskog paketa EMTPDraw. Analiziran je utjecaj dalekovodnog polja na oblik i iznos povratnog prijelaznog napona na prekidaču prilikom prekidanja struje bliskog kratkog spoja. Simulacijama u EMTPDraw-u određeno je mjesto (udaljenost) bliskog kratkog spoja na kojem je iznosom najveća strmina početnog povratnog prijelaznog napona. Less
Abstract (english)
The paper explains the principles of extinguishing direct current and alternating current, the procedure for extinguishing an electric arc when interrupting alternating current by comparing an ideal and a real switch is given. The concepts of bus short circuit and close short circuit are explained with the given example. The recovery voltage as the basis of the analysis is defined with the associated components. A 400 kV plant is described, which is the subject of... More analysis in actual operating condition with actual data. The modelling of the 400 kV plant using the EMTPDraw software package is presented in detail. The influence of the power line field on the shape and amount of the transient recovery voltage on the circuit breaker when interrupting the current of a near short circuit was analyzed. Simulations in EMTPDraw determined the location (distance) of the close short circuit where the rate of rise of recovery voltage is the highest. Less
