Abstract
U radu se analiziraju udarni nesimetrični kratki spojevi sinkronog generatora. Izrađeni su matematički modeli za proračun nesimetričnih kratkih spojeva na vodovima i stezaljkama generatora priključenog na elektroenergetski sustav te u autonomnom radu. Model generatora proširen je matematičkim modelom mehaničkog sustava rotora turboagregata. Proračunavaju se torzijski momenti u osovini agregata pri nesimetričnim kratkim spojevima na primjeru velikog turboagregata. Na laboratorijskom modelu agregata obavljena su mjerenja električnih veličina i torzijskih momenata pri udarnim kratkim spojevima: tropolnom, dvopolnom, dvopolnom dozemnom i jednopolnom dozemnom. Dobiveni rezultati uspoređuju se s rezultatima proračuna.
Abstract (english)
Unbalanced short circuits of a synchronous generator are analyzed. Mathematical models for calculating transients at unbalanced short circuits occurring on transmission lines and generator terminals are developed. A mathematical model of a turbine-generator set mechanical system for the analysis of torsional vibrations is appended to the models. Torsional torques in the turbine shaft at unbalanced short circuits are calculated with data from a large turbogenerator set. Measurements of torsional torques at phase-to-neutral, phase-to-phase, two-phases-to-neutral and triple-phase short circuits has been carried out on a laboratory model. The results of the measurements are compared to the results calculated by the mathematical models.
