Sistem besprekidnog napajanja snage 120 kVA u termoelektrani Kostolac A - invertori u paralelnom radu
Ključne reči:
invertori, paralelan rad, besprekidno napajanje
Sažetak
Sistemi besprekidnih napajanja su od vitalnog značaja za mnoge potrošače u složenim kompleksima poput termoelektrane. U ovom radu prikazano je rešenje paralelnog rada dva invertora nominalnih snaga 60 kVA, zasnovano na kontroli prirode invertora. Predočeni su svi izazovi i tehnički detalji paralelizacije dva invertora, od ravnomernog deljenja opterećenja, preko komunikacije i uspostavljanja „master-slave“ odnosa, pa sve do tranzijentnih pojava pri ispadu jednog od invertora. Prikazane su detaljne simulacije u softverskom alatu Plecs svih relevantnih pojava i fenomena, shodno proračunu razvijeni su invertori a priloženi su i eksperimentalni rezultati rada ovih invertora u simuliranim eksploatacionim uslovima.
