Abstract

Povećanje broja nepredvidivih izvora električne energije poput vjetroelektrana u elektroenergetskim sustavima dolazi do brojnih nesigurnosti u planiranju rada tih sustava. Kako bi vjetroelektrane imale što bolji utjecaj na rad EES-a potrebno je odabrati adekvatan tip vjetroagregata za vjetroelektranu. U ovom radu su istraženi utjecaji vanjkog kvara u mreži na asinkroni kavezni generator (AKG), dvostruko napajani asinkroni generator (DFIG) i sinkroni generator s permanentnim magnetima (PMSG).... More Istražen je utjecaj kvara na dinamičko ponašanje navedena tri agregata te je proveden proračun prijelazne stabilnosti. Posebno je istražena osjetljivost pojednih parametara agregata koji je u vezi s prijelaznom stabilnosću. Less

Abstract (english)

Increasing the number of unpredictable electricity sources such as wind power plants in power systems results in numerous uncertainties in the planning of these systems. In order for wind power plants to have the best impact on EES work, it is necessary to select an adequate wind turbine type for the wind power plant. In this paper, the effects of external fault in the networks on the squirrel cage induction generator (AKG), the doubly fed induction generator (DFIG) and the permanent magnet... More synchronous generator (PMSGs) are investigated. The impact of the fault on the dynamical behavior of the three aggregates was investigated and the calculation of transient stability was carried out. Particularly, the sensitivity of certain aggregate parameters related to transition stabilization has been studied. Less
