Abstract
U završnom radu se prikazuje isključenje visokonaponske prigušnice modelirane u DigSilent Power Factory programu instalirane jalove snage 50 Mvar, 100 Mvar i 1000 Mvar. U programskom paketu je provedeno 9 simulacija. Isključenje faze prigušnice se ne odvije trenutno zbog akumulirane energije u prigušnici. Isključenje jedne faze prigušnice u maksimalnoj vrijednosti struje stvara oscilacije na sabirnici i na prigušnici. Maksimalna vrijednost prenapona se povećava povećanjem reaktancije prigušnice. Prilikom isključenja sve tri faze prigušnice u maksimalnoj vrijednosti u fazi A se stvara prenapon na prigušnici kojem je maksimalna vrijednost negativnog predznaka, za razliku kod isključenja u minimalnoj vrijednosti gdje se stvara prenapon na prigušnici pozitivnog predznaka. Prilikom isključenja sve tri faze prigušnice oscilacije na prigušnici i sabirnici prestaju nakon isključenja sljedeće faze.
Abstract (english)
In the final paper, the disconnection of the high-voltage shunt modeled in the DigSilent Power Factory program installed reactive power 50Mvar, 100Mvar i 1000Mvar. 9 simulation were carried out in the program package. Shutdown of the shunt phase does not take place at the moment due to the accumulated energy in the shunt. Switching off one phase of the choke at the maximum value of the current creates oscillations on the bus and on the choke. The maximum overvoltage value increases by increasing the choke reactance. When switching off all three phases of the choke at the maximum value in phase A, an overvoltage is created on the choke with a maximum value of negative sign, unlike when switching off at a minimum value, where an overvoltage is created on the choke with a positive sign. When switching off all three phases of the choke, the oscillations on the choke and the bus stop after switching off the next phase.
