Zmanjševanje izgub s preoblikovanjem omrežja : magistrsko deloHorvat, MiranZaradi zanesljivosti obratovanja je razdelilno (distribucijsko) omrežje v gosteje naseljenih področjih običajno zgrajeno v zankasti obliki, v času obratovanja po so zanke prekinjene. Večkrat se ... zgodi, da nastala oblika omrežja ne omogoča obratovanja z najmanjšimi izgubami. Preoblikovanje (rekonfiguracijo) omrežja dosežemo v distribucijskih omrežjih s spremembo stanja stikalnih naprav, ki povezujejo oz. ločujejo posamezne dele omrežja z namenom zmanjšanja delovnih izgub. V tem delu sem se posvetil obravnavi zmanjšanja izgub distribucijskih omrežij s pomočjo preoblikovanja omrežja ter analitičnim metodam, ki se pri rekonfiguraciji omrežja največ uporabljajo. Predlagal sem novo metodo, ki temelji na natančnem izračunu pretokov moči in upošteva vse zahtevane parametre omrežja. Hitrost predlagane metode in ostalih obravnavanih metod je odvisna predvsem od števila povezav v omrežju, tako tistih ki obratujejo, kot tistih, ki so v normalnem obratovalnem stanju izven obratovanja. Za uspešno uporabo metode v realnem času je zelo pomembno, da metoda da rezultat v čim krajšem času. S pomočjo računalniškega programa, ki sem ga realiziral, poiščem tako obliko omrežja, ki ustreza vsem obratovalnim zahtevam og pogoju najmanjših delovnih izgub. Programski paket je mogoče ob primerni strojni opremi uporabiti tudi v realnem času. Dispečerju predlaga najboljšo rešitev, skladno s stanjem v omrežju pa se le ta odloči za izvršitev spremembe oblike omrežja. S pomočjo testnih primerov in na realnem primeru mariborskega elektroditribucijskega omrežja sem primerjal obstoječe metode in predlagano metodo.Type of material - master's thesisPublication and manufacture - Maribor : [M.
