Abstract
U ovom radu analizirane su visokoimpedantna i niskoimpedantna diferencijalna zaštita sabirnica koje se koriste u elektroenergetskom sustavu. Osim teorijskog objašnjenja, prikazan je primjer pomoću uređaja 7SS85 kojem je glavna funkcija zaštita sabirnica. Implementiranje samog uređaja prikazano je u programskom alatu DIGSI 5 tvrtke Siemens. U prvom poglavlju rada opisane su moguće konfiguracije sabirnica koje postoje u elektroenergetskom sustavu od kojih su najčešće izvedbe jednostruke sabirnice sa ili bez sekcioniranjem te dvostruke sabirnice. Nadalje, opisane su najvažnije zaštite koje se koristi za zaštitu sabirnice, a to su visokoimpedantna diferencijalna zaštite sabirnice te niskoimpedantna. Navedeni su njihovi načini spajanja, prednosti i mane. U četvrtom poglavlju ukratko su opisani releji 7SS6x niskoimpedantne zaštite sabirnica te 7SJ8x kojem je jedna od funkcija visokoimpedantna zaštita sabirnica. Na samom kraju opisan je postupak podešavanja zaštitnog releja 7SS85 SIPROTEC 5 generacije tvrtke Siemens te način parametriranja samog uređaja na primjeru HE KOSINJ 110 kV.
Abstract (english)
This work analyses low impedance busbar differential protection and high impedance busbar differential protection in the power system. In addition to the theoretical explanation, an example of busbar protection using a device 7SS85 whose main function is busbar protection. The implementation of the device is shown in the software tool DIGSI 5 of the company Siemens. In the first chapter, the possible busbar configurations that exist in the power system are described. The most common configurations are single busbar with or without sectioning and double busbar configuration. Furthermore, the main protection used for busbar protection are described which are high impedance and low impedance differential busbar protection. Differences between them, their prons and cons are mentioned. The fourth chapter briefly describes relays 7SS6x low impedance busbar protection and 7SJ8x whose high impedance busbar protection is one of its functions. The end of the work explains the procedure for adjusting the protection relay 7SS85 SIPROTEC 5 generation from Siemens and the method of parameterizing the device using the example of HE KOSINJ 110 kV.
