Abstract
U ovom radu analizirani su različiti tipovi relejnih zaštitnih uređaja koji se koriste za zaštitu komponenti u elektroenergetskom sustavu. Osim teorijske analize ti uređaji su prikazani na primjeru zaštite vlastite trafostanice 110/30 kV. Kroz programski paket DIGSI 5 tvrtke Siemens pokazan je rad sa zaštitnim uređajima i princip njihovog optimiranja. Na početku samog rada opisane su najvažnije zaštite koje se koriste u distribucijskim mrežama. Glavna podjela je na nadstrujnu zaštitu i zaštitu energetskog transformatora. Navedeno je područje primjene svih zaštita, kod kojih vrsta kvarova se javljaju te njihove prednosti i mane. Treće poglavlje rada odnosi se na usporedbu raznih zaštitnih uređaja tipa 7SJ8x i 7UT8x. Navedene su razlike među njima te područje primjene za koje su predviđeni. Kraj samog rada i najvažniji dio, posvećen je opisu postupka i parametrizacije svih zaštitnih uređaja korištenih za zaštitu trafostanice 110/30 kV sa 5 polja. Za zaštitu ovog postrojenja korištena su tri zaštitna uređaja 7SJ82, 7SJ85 i 7UT85. Riječ je o uređajima posljednje generacije SIPROTEC 5 marke Siemens, koji su jedni od trenutno najmodernijih i najsofisticiranijih uređaja za relejnu zaštitu na tržištu.
Abstract (english)
This work analyses different types of relay protection devices which are used for protection of equipment in electroenergetical system. Except theoretical analyses the same protection devices are used for example of protecting own substation 110/30 kV. Throught Siemens DIGSI 5 software package, work with protective devices and the principle of optimization are demonstrated. At beginning of the work, the most important protections used for protection distribution network are described. Main division is on overcurrent protection and on protection of energy transformer. Application of all protections is specified, types of failures where they occur and their pros and cons. Third chapter of paper describes comparison between different protection devices of type 7SJ8x and 7UT8x. Differences between them and application for which they are specified is also mentioned. The end of the work and most important part of it is dedicated to the description and parametrization of all protection devices used for protection substation 110/30 kV with 5 fields. For protection of this substation, three protection devices 7SJ82, 7SJ85 and 7UT85 are used. These are devices of the last generation SIPROTEC 5 brand Siemens, which are currently the most modern and most sophisticated devices for protection on the market.
