Abstract
U doktorskoj disertaciji analizirani su problemi stabilizacije elektromehaničkih njihanja sinkronog generatora. Zbog nedostataka klasičnih postojećih rješenja predložen je novi algoritam stabilizacije temeljen na promatranju stanja generatora u trodimenzionalnom prostoru koji čine odstupanje brzine vrtnje, ubrzavanje rotora generatora i odstupanje kuta opterećenja generatora. Definirana su upravljačka pravila po kojima će stabilizator minimizirati trajektoriju gibanja generatora u prostoru stanja nakon nastanka poremećaja. Od stabilizatora je zahtijevana robusnost s obzirom na promjenu frekvencije njihanja i promjene stanja sustava. Izrađeni su simulacijski modeli novopredloženog trodimenzionalnog stabilizatora i klasičnih rješenja stabilizatora i to stabilizatora temeljenog na djelatnoj snazi te stabilizatora temeljenog na integralu snage ubrzavanja. Predloženi algoritmi implementirani su u digitalni sustav temeljen na procesoru za obradu signala i ispitani eksperimentalno na sinkronom generatoru, koji je preko modela prijenosnih vodova i transformatora spojen na elektroenergetski sustav. Na osnovu usporedbi odziva i numeričkih kriterija valorizirana su djelovanja pojedinih stabilizatora. Zaključeno je da stabilizator temeljen na djelatnoj snazi ne zadovoljava u uvjetima skokovite promjene djelatne snage, da stabilizator temeljen na integralu snage ubrzavanja ne zadovoljava u uvjetima promjene frekvencije njihanja (potrebno dodatno podešavanje parametara) te da trodimenzionalni stabilizator u svim režimima rada postiže zadovoljavajuće prigušenje elektromehaničkih njihanja.
Abstract (english)
This doctoral thesis analyses the issues pertaining to the synchronous generator power system stabilizer. It is proposed a new power system stability algorithm based on observing the generator state in a three-dimensional space a made by speed deviation, and of generator acceleration as well as generator load angle deviation. The control rules ensure the stabilizer will minimize the generator's movement trajectory within the space after a disturbance. The stabilizer must be robust given the oscillation frequency change and the change in the system's state. Simulation models of the three-dimensional stabilizer have been made, as well as a stabilizer based on active power and a stabilizer based on the integral of accelerating power. The suggested algorithms were implemented into a digital control system and tested experimentally on an synchronous generator connected to an AC system. The stabilizers effects were valorized based on a comparison of experimental responses. It was concluded that the stabilizer based on active power does not satisfy under the conditions of active power step change and that the stabilizer based on the integral of accelerating power does not satisfy under conditions of changed oscillations frequency whereas the three-dimensional stabilizer achieves satisfactory power system stability under any work conditions.
