Abstract

Ovaj rad obrađuje problematiku pogona prijenosne mreže u uvjetima povišenih napona. Do pojave povišenih napona u prijenosnim mrežama u pravilu dolazi u uvjetima slabog opterećenja EES-a i malih tranzita snage. Za potrebe regulacije napona i kompenzacije jalove snage koriste se različiti kompenzacijski uređaji zasnovani na kombinaciji prigušnica i kondenzatorskih baterija. Osim klasičnih uređaja (generatori, sinkroni kompenzatori, prigušnice i dr.), u posljednje se vrijeme sve više u prijenosnim mrežama koriste kompenzacijski uređaji zasnovani na energetskoj elektronici. Detaljno su opisani uređaji za kompenzaciju jalove snage i održavanje napona u dozvoljenim granicama. Također osvrnulo se i na probleme povišenih napona u hrvatskoj prijenosnoj mreži, te su opisane mjere koje dispečerima u NDC-u stoje na raspolaganju za snižavanje previsokih napona.

Abstract (english)

This paper deals with the issue of the transmission network in terms of increased voltage. The appearance of increased voltage in transmission networks typically comes in low-load power system and small transit power. For regulation of voltage control and reactive power compensation different compensation devices based on a combination of reactors and capacitor batteries are used. Besides the classic equipment (generators, synchronous compensators, reactors, etc.), in recent times more and more transmission networks using compensation devices based on power electronics. In this paper there are detailed described devices for reactive power compensation and maintain voltage levels. The problems of increased voltage in the Croatian transmission network is also commented and describes measures that dispatchers in NDC are available to reduce over-voltage.
