Abstract

Danas, niskonaponska mreža doživljava preobrazbu kako bi zadovoljila potražnju za neprekinutim napajanjem. U takvim uvjetima, gdje je gubitak snage kritičan, Inteligentni prekidač niskog napona (LVCB) ima važnu ulogu kako bi osigurao troškovno učinkovito I otporno napajanje miikromreže, uz učinkovito integriranje zelene energije koju pružaju obnovljivi izvori. LVCB, se stoga transformira iz primitivnog pružatelja zaštite u centralnog upravitelja mikromrežom. U prvom dijelu, ovaj rad daje pregled komercijalnog LVCB-a I njegovih značajki, dok drugi dio daje studiju slučaja koja se sastoji od testiranja proradne karakteristike, dio LVCB-ovog FAT i SAT postupka, korištenjem isključivo komercijalno dostupnog programskog alata (LabView).

Abstract (english)

Nowadays, low voltage network experiences transformation to meet the demand for un-interrupted power supply. In such environment where loss of power is critical, intelligent Low Voltage Circuit Breaker (LVCB) plays major role to provide cost efficient and resilient power supply to a Microgrid while effectively integrating green energy provided by RES. Thus, LVCB is transforming from sole protection provider to a central controller managing the whole Microgrid by itself. In the first part, this work provides an overview of the commercial LVCB and its features while the second part gives a case study of testing protection curves, part of LVCB’s FAT and SAT procedure, by using only off-the-shelf software (LabView).
