Abstract

U teoretskom dijelu opisano je ponašanje međusobno povezanih sustava na modelu mreže s dva čvorišta i jednim vodom. Opisani su mehanizmi upravljanja tokovima snaga.
Uveden je koncept FACTS (Flexible Alternate Current Transimission System) uređaja. Dan je pregled i osnovna podjela FACTS uređaja. Obrađene su pojedine kategorije FACTS uređaja s naglaskom na njihove međusobne razlike i funkcije.
Opisan je i mehanizam upravljanja iznosom i kutom napona. Definirani su regulatori napona i kuta te je objašnjenja fundamentalna razlika u principu njihovog djelovanja. Opisan je utjecaj na tokove snage regulatora faze ili transformatora sa zakretom faze (PST - phase shifting transformer ili PAR - phase angle regulator).
U praktičnom dijelu, demonstrirana je primjena određenih vrsta FACTS uređaja (TCSC, UPFC) i PST-a u upravljanju tokovima snaga na modelu mreže od četrdeset i osam čvorišta baziranom na standardnoj testnoj IEEE mreži od dvadeset i četiri čvorišta. U proračunu je korišten programski alat NEPLAN.

Abstract (english)

In the theoretical part the behavior of an interconneced transmission system was described on a two node and one line network model. The mechanisms of power flow control were described as well.
The concept of FACTS(Flexible Alternate Current Transimission System) devices was introduced. The overview and basic division of FACTS devices was given. Categories of FACTS devices with emphasis on their mutual differences and functions were describes.
The mechanism of voltage magnitude and angle regulation was also givne. Phase angle and voltage regulators were defined and the basic difference in their operational principe was explained. The influence of the phase shifting transformer or phase angle regulator on the power flow was described.
In practical sense, the use of certain types of FACTS devices (TCSC, UPFC), and phase- shifting transformer in power flow control was demonstrated on the standard IEEE 48 - nodes network model.
NEPLAN programming tool was used in all calculations.
