Abstract
Napon možemo regulirati u beznaponskom stanju ili pod opterećenjem. Osim uzdužne (U-Q) regulacije, postoje poprečna i kosa regulacija napona kojima se može utjecati na tokove djelatne snage u mreži. Ovisno o spoju glavnog i regulacijskog namota postoje linearna regulacija, regulacija prekretanjem te predbiranjem. Energetski transformatori gotovo uvijek imaju mogućnost regulacije napona pod opterećenjem i važan su element elektroenergetskog sustava. Regulacijska sklopka služi za promjenu prijenosnog omjera transformatora, tj. za preklapanje između izvoda regulacijskog namota bez prekida prijenosa električne energije. Regulacijskom sklopkom upravlja (automatski) regulator napona. Njegov zadatak je nadzirati mjerene veličine - struje i napone, a ako dođe do poremećaja, nakon zadanog vremenskog kašnjenja, potrebno je poslati signal regulacijskoj sklopki za promjenu položaja kako bi se napon vratio u dozvoljene granice.
Abstract (english)
Voltage and frequency supervision and control is main task in power system. If they are kept between allowed boundaries, power system will distribute and transmit electrical energy reliably. Power transformers usually have tap changer devices for voltage control. They allow transformer turn ratio to be changed. There are two types of tap changers: de-energized tap changers - DETC (transformers must be de-energized before the turn ratio is adjusted) and on load tap changers - OLTC (transformers may adjust their turn ratio during operation). Voltage regulators are devices used for monitoring and managing tap changers. Usually they operate automatically according to predefined settings. Thay can be controlled from remote control centers.
