Abstract.
This paper presents theoretical and experimental results of self-excited induction generator under varying rotor speed operation research. Three-phase squirrel-cage 1.5 kW induction machine, excited with symmetrical capacitor bank and loaded with symmetrical three-phase resistive load, was the subject of investigation. Experimentally obtained results have been compared with calculated performance curves and very good agreement between them has been achieved.
Key Words:
induction generator, self-excitation, variable speed.
RAD SAMOPOBUDNOG ASINHRONOG GENERATORA PRI KONSTANTNOJ KAPACITIVNOSTI I PROMENLJIVOJ BRZINI
U radu su predstavljeni rezultati teorijskog i eksperimentalnog proučavanja trofaznog samopobudnog asinhronog generatora u uslovima kostantne kapacitivnosti pobudnih kondenzatora i varijabilne brzine rotora. Eksperimenti su izvedeni na trofaznoj asinhronoj mašini sa kaveznim rotorom snage 1.5 kW, koja je bila pobuđena simetričnom trofaznom kondenzatorskom baterijom i opterećena simetričnim trofaznim potrošačem aktivne prirode. Vrednosti dobijene eksperimentalnim putem upoređene su sa proračunatim radnim karakteristikama, pri čemu je postignuta veoma visoka podudarnost.
Ključne reči:
