Reactive power compensation devices in HV electrical networks

Ovaj rad obrađuje uređaje za kompenzaciju jalovih snaga u visokonaponskim mrežama. Opisane su strukture elektroenergetskog sustava i o čemu ovisi kvaliteta električne energije. Kroz rad detaljno je opisano nastajanje jalove snage i vrste kompenzacije u postrojenjima. Također prikazani su elementi od kojih se sastoji kompenzacijski uređaj i postupak plaćanja prekomjerne preuzete jalove energije. Opisana je struktura i rad FACTS tehnologije u elektroenergetskim postrojenjima. Prikazane su prednosti i mane prilikom ugradnje kompenzatora u mrežu.This paper deals with reactive power compensation devices in high voltage networks. The structures of the electrical power system are described, as well as on what does the quality of electricity depend on. Throughout the work the generation of reactive power and types of compensation in the plants are described in detail. The elements the compensating device consists of and the process of payment of reactive power excess charging are presented. The structure and operation od FACTS technology in the power plants and advantages and disadvantages of installing the compensator in the network are shown as well
