Abstract

Tema ovog diplomskog rada je detaljniji uvid u primjenu sinkronog generatora s permanentnim magnetima u hidroelektranama s malim padom vode. Opisane su tehničke specifikacije sinkronog generatora s permanentnim magnetima, a posebice onoga s vanjskim površinskim magnetima preko matematičkog modela te fazorskog dijagrama. Napravljena je osnovna usporedba specifikacija s asinkronim generatorom. Uz to je opisan i frekvencijski pretvarač s aktivnim ispravljačem, metode upravljanja sklopkama pretvarača te izvedba istosmjernog međukruga i mrežnog filtera. Na kraju su izvedene simulacije iz kojih se dobiju odzivi električnih veličina za karakteristične pogone sinkronog generatora s permanentnim magnetima sa i bez frekvencijskog pretvarača.

Abstract (english)

The topic of this Master's thesis is a detailed insight into the application of a permanent magnet synchronous generator in hydropower plants with low water drop. The technical specifications of a permanent magnet synchronous generator are described, especially the one with external surface magnets via a mathematical model and phasor diagram. A basic comparison of the specifications with the asynchronous generator was made. In addition, a frequency converter with an active rectifier, methods of converter switch control, the design of a DC link and a grid filter are described. Finally, simulations are performed from which the responses of electrical quantities for the characteristic drives of a permanent magnet synchronous generator with and without a frequency converter are obtained.
