Abstract
Proširenje tržišta električne energije s mnogobrojnim proizvođačima i potrošačima nametnulo je velike izazove u vidu održanja ravnoteže mreže i zadovoljenja potreba kupaca. Potreba za pojmom kvalitete električne energije nametnula se po prirodi jer je električna energija postala roba koja tada kao i svaka druga mora imati mjerljive parametre kvalitete, propisane normama i zakonima. Jedan od ključnih parametara električne energije je kvaliteta napona. Širok je spektar uzroka koji na razne načine mijenjaju svojstva napona, a svaka promjena tih svojstava u odnosu na one nazivne rezultira smanjenjem kvalitete električne energije. Iznos napona, kao temeljno svojstvo napona uz njegovu frekvenciju, nužno je održavati u određenim granicama. Regulacija napona na energetskim transformatorima pod opterećenjem omogućava održavanje napona u čvorištima mreže u propisanim granicama bez obustave napajanja. Automatska regulacija napona odrađuje se kombinacijom regulatora i regulacijske sklopke. Regulator usporedbom mjerenih veličina struje i napona s onim zadanim daje nalog regulacijskoj sklopci za promjenu prijenosnog omjera transformatora, a samim time i regulira napon na sekundaru transformatora.
Abstract (english)
Expansion of electrical energy market with numerous customers and suppliers has brought great challenges in terms of keeping network balance combined with satisfaction of customer needs. A call for term of electrical energy quality has come by its nature because electrical energy has become a merchandise which must be recognizable by its quality parameters, prescribed with norms and law. One of key properties of electrical energy is voltage quality. There is a wide spectre of causes which affect voltage parameters in variety of ways. Each change in those properties in regards to nominal results as reduction of electrical energy quality. Voltage amplitude, as fundamental voltage property along its frequency, must be held within prescribed limits. On –load voltage regulation on power transformers allows keeping voltage amplitude in network nodes within prescribed limits without supply suspension. Automatic voltage regulation is done by combination of regulator and tap changer. Regulator compares measured values of current and voltage with appointed ones. If difference occurs, regulator gives tap changer an order to change winding ratio and hence regulate voltage amplitude on transformer secondary winding.
