VOLTAGE REGULATION IN DISTRIBUTION NETWORKS WITH DISTRIBUTED SOURCES

Ovaj diplomski rad govori o regulaciji napona u distribucijskim mrežama. Prikazana je struktura i topologija distribucijskih mreža. Obrađena je klasična regulacija napona te njeni elementi, odnosno automatska regulacija napona i regulacijska sklopka na transformatorskim stanicama TS 110/20 kV, te fiksna regulacija napona u beznaponskom stanju na transformatorskim stanicama TS 20/0,4 kV. Opisuje se i analitički obrađuje utjecaj distribuiranih izvora na klasičnu regulaciju napona. Razrađeni su modeli nadogradnje klasične regulacije napona vođeni idejom da se korekcijom struje na sekundaru poništi utjecaj distribuiranih izvora na regulaciju napona.The thesis deals with voltage regulation in distribution networks. The structure and topology of distribution networks are as well illustrated. Classical voltage regulation and its elements, i.e. automatic voltage regulation and control switch on transformer stations TS 110/20 kV, as well as fixed voltage regulation in voltageless state on transformer stations TS 20 / 0,4 kV, have been elaborated. The influence of distributed sources on classical voltage regulation is described and analyzed. Models of upgrading of classical voltage regulation have been elaborated in detail, guided by the idea that the correction of the current at the secondary eliminates the influence of distributed sources on voltage regulation
