Abstract

Analiza stabilnosti elektroenergetskog sustava (EES-a) u tranzientnom periodu jedna je od znacajnijih analiza i radi se u svakom EES-u. Kod ove analize promatraju se brze promjene, kao posljedica uglavnom kratkih spojeva u mrezi, koje izazivaju njihanja rotora generatora. Pojedina elektrana utjece na pomenutu stabilnost preko elektricnih i mehanickih konstanti generatora i pogonskih strojeva te regulatora uzbude generatora i turbinskih regulatora. Ovo zajedno s postojecim elektricnim vezama izmedu genaratora (transformatori, vodovi) te odredenim tipom poremecaja odreduje da li ce stabilnost sustava biti sacuvana. U ovom radu se analizira utjecaj mjesta kratkog spoja na ponasanje revitaliziranih generatora HE Zakucac i generatora HE Orlovac u tranzientnom periodu.
