KONČAR Electronics and informatics has signed a contract for Main generator excitation system supply at NPP Krško KONČAR Electronics and informatics has signed a contract for Main generator excitation system (without brushless exciter) supply and replacement at NPP Krško. KONČAR excitation systems’ design meets all tender requirements, and it will improve plant reliability with new dual-channel configuration significantly. Moreover, an excitation human-machine interface and ability to connect with PDEH (which are further options) allow simplified operation, monitoring and maintenance. The Contract comprises dismantling of existing regulator and supply new automatic voltage regulator with all necessary cables, modification in control system of NPP Krško, simulation study and study of impact on generator-transformer protection system as well as commissioning of new excitation system. Deadline for factory acceptance test for new equipment is June 2016., and for commissioning October 2016.

Pušten u pogon novi AVR glavnog generatora u NE Krško Končar Elektronika i informatika nedavno je uspješno pustila u pogon automatski regulator napona (AVR) za glavni generator 880MVA u NE Krško i postojeći uzbudnik. Končar je ovaj projekt izveo na principu “ključ u ruke”. Opseg isporuke je sadržavao demontažu postojećeg WTA regulatora i isporuku novog regulatora napona sa svim potrebnim kabelima, prilagodbama u sustavu upravljanja NE Krško, simulacijsku studiju i studiju utjecaja na zaštitu glavnog generatora i transformatora kao i testiranje i puštanje u pogon novog AVR-a. Kako bi se zadovoljili svi tenderski uvjeti, uzbuda je izvedena u dvokanalnoj konfiguraciji s 1+1 tiristorska mosta. Sljedeće godine, tijekom redovnog remonta u NE Krško, Končarevi specijalisti podesit će parameter regulatora prema novom uzbudniku koji će biti instaliran.
