Abstract

Elektrenergetski sustav podložan je svakojakim kvarovima i promjenama. Stabilnost elektroenergetskog sustava ključna je za kvalitetnu i konstantnu opskrbu potrošaća. Frekvencija i napon su glavni parametri za analizu stabilnosti sustava. Praćenjem vrijednosti napona i frekvencije reagiramo u skladu potreba. Raznim regulacijskim uređajima utječemo na poremećaj. Transformatori s mogučnošću regulacije tu imaju veliku ulogu. PST transformatori odnosno transformatori s zakretom faze omogućuju preusmjeravanje tokova snaga ovisno o potrebama sustava. OLTC transformatori utječu na iznos transformiranog napona djelujući na prijenosni omjer. Unaprijed organiziranim postavkama u transformatorskim stanicama potrebno je uskladiti rad regulacijskih transformatora radi smanjenja gubitaka i troškova.

Abstract (english)

The power system is subject to all kinds of failures and changes. The stability of the power system is crucial for a quality and constant supply to consumers. Frequency and voltage are the main parameters for system stability analysis. By monitoring the voltage and frequency values, we react according to needs. We use various control devices to influence the disturbance. Transformers with the possibility of regulation play a big role here. PST transformers or phase shift transformers enable redirection of power flows depending on the needs of the system. OLTC transformers affect the amount of transformed voltage by acting on the gear ratio. Pre-arranged settings in transformer stations need to harmonize the operation of control transformers in order to reduce losses and costs.
