Abstract
Ovaj rad se konceptualno može podijeliti u tri dijela. U prvom dijelu objašnjen je osnovni princip rada i konstrukcija sinkronog generatora te su navedeni mogući kvarovi i opasna pogonska stanja koja mogu uzrokovati oštećenjem ili nestabilnosti generatora. Sinkroni generator najvažniji je i najskuplji uređaj elektroenergetskog sustava te zbog toga zaštita generatora predstavlja veoma važnu granu elektrotehnike. U drugom dijelu detaljno su objašnjene osnovne i najčešće korištene tehnike zaštite generatora od kratkih spojeva statora i rotora. Objašenjena je diferencijalna zaštita koja predstavlja osnovnu tehniku zaštite od međufaznih kratkih spojeva i od kratkih spojeva među zavojima iste faze. Zaštiti od zemljospoja statora posvećena je posebna pažnja, budući da je zemljospoj najčešći tip kvara na generatoru te se neki kvarovi i opasna pogonska stanje ne prepoznaju sve dok ne rezultiraju zemljospojem statora. Tehnika zaštite od zemljospoja uvelike ovisi o vrsti uzemljenja, a kod velikih visokoimpedantno uzemljenih generatora nastoji se postići 100% zaštita statora. U trećem dijelu navedene su osnovne tehnike zaštite od opasnih pogonskih stanja i vanjskih kvarova. Adekvatna zaštita nužna je za opasna pogonska stanja zbog mogućnosti nastanka ozbiljnih oštećenja generatora kao i opasnosti za čitav sustav.
Abstract (english)
This project can be separated in three parts. First part explains synchronus generator contruction and working fundamentals. All the generator faults and abnormal operating conditions that can cause damage and jeopardize stability of generator and power system have been mentioned. Synchronus generator is the most important and most expensive machine in the power system so generator relay protection represents very important branch of electrical engineering. Second part explains protection against internal faults. Differential protection represents the most important protection scheme for stator phase faults. For stator turn to turn faults most used protection scheme is spli-phase protection. Beacuse of stator winding construction, an insulation failure is more likely to result in a ground fault than in phase to phase fault. This project explains a varietly of protection schemes for simple stator ground faults depeding on grounding of generator. It also explains different methods for achieving 100% stator protection. Third part discusses most commonly used protection schemes for abnormal operating conditions and external faults. Reliable protection schemes are very important as abnormal conditions can cause serious damage to generator and jeopardize power system stability.
