Abstract
U ovom radu su predstavljeni problemi povišenih napona elektroenergetskog sustava. Razmotrene su različite metode regulacije napona, s posebnim naglaskom na prigušnice za kompenzaciju jalove snage. Promatrana je mreža Gorskog kotara zbog rijetke naseljenosti i niske potrošnje električne energije što dovodi do nepovoljnih naponskih prilika. Kabliranje mreže zbog vremenskih nepogoda povećava kapacitivnost vodova. Kao rješenje, razmatra se ugradnja regulacijskih prigušnica u nekoliko trafostanica gdje je od izrazite važnosti odabrati pravovaljanu snagu te poziciju prigušnica. Simulacije su provedene u programu NEPLAN, koristeći model koji preslikava stvarno stanje mreže. Usporedba stanja mreže prije i nakon ugradnje prigušnica pokazuje da se problem povišenih napona rješava, struje kroz vodove smanjuju, a kapacitivno opterećenje transformatora se smanjuje, što poboljšava regulaciju napona i faktor snage. Ovo donosi mnoge pozitivne učinke, uključujući povećanje strujne opteretivosti vodova, smanjenje gubitaka i poboljšanje naponskih prilika.
Abstract (english)
In this paper, the issues of overvoltages in the power system are presented. Various voltage regulation methods are considered, with a special focus on reactors for reactive power compensation. Gorski kotar network is examined due to its low population and low electricity consumption, which leads to unfavorable voltage conditions. The cabling of the network due to adverse weather conditions increases the capacitance of the lines. As a solution, the installation of regulating reactors in several substations is considered, where selecting the appropriate power and position of the reactors is of great importance. Simulations were conducted in the NEPLAN software, using a model that accurately mirrors the real state of the network. The comparison of the network's state before and after the installation of reactors shows that the overvoltage problem is resolved, the currents through the lines are reduced, and the capacitive load on the transformers is decreased, improving voltage regulation and power factor. This brings many positive effects, including increased current-carrying capacity of the lines, reduced losses, and improved voltage conditions.
