Abstract

Prijenosna mreža je jedan od najvažnijih dijelova elektroenergetskog sustava. Proračun tokova snaga daje podatke o zagušenjima u mreži, podopterećenosti i preopterećenosti te sigurnosti sustava. Vjetroelektrane čine značajan udio u ukupnoj proizvodnji hrvatskog elektroenergetskog sustava. U Dalmaciji je smješten najveći dio vjetroelektrana, koji uz hidroelektrane čini okosnicu proizvodnje tog područja. Pomoću programskog paketa PSS/E napravljena je simulacija za proračun tokova snage pomoću Newton - Raphson metode i analiziralo se gdje bi moglo doći do zagušenja u prijenosnoj mreži. U modeliranoj mreži je trebalo prilagođavati proizvodnju i potrošnju za više stanja. Radilo se početno stanje, prijelazno u kojem se povećava proizvodnja i isključuje pojedini vod te završno stanje s maksimalnom proizvodnjom i pojavom zagušenja u mreži.

Abstract (english)

The transmission network is one of the most important parts of power system. Power flow calculation provides data about the network congestion, underload, overload and the system security. Wind power plants make a significant part in the total production of Croatian power system. Most of the wind power plants are located in Dalmatia and along the hydro power plants they form the main production in this area. Using the PSS/E software package a simulation was made for the calculation of power flows using the Newton - Raphson method and analysed where the congestion could occur in the transmission network. In the network model needed to adjust production and consumption for more conditions. It was made the initial condition, the transition condition in which the production was increased and some of lines were turned off and the final condition with the maximum production and appearance of congestion in network.
