Abstract

Održavanje napona u dozvoljenim granicama uz što manje gubitaka vrlo je zahtjevan posao koji se stavlja pred operatora prijenosnog sustava u procesu vođenja pogona. Taj se problem dodatno komplicira većim brojem kompenzacijskih uređaja kada je efikasnu regulaciju napona i jalove snage moguće ostvariti na više različitih načina. U takvim uvjetima posebnu pozornost potrebno je obratiti koordiniranoj regulaciji napona i jalove snage. Teoretski je obrađena problematika koordinirane regulacije napona i jalove snage u prijenosnim elektroenergetskim mrežama. Opisani su kompenzacijski uređaji s kojima se to ostvaruje kao što su to regulacijske prigušnice, statičkih VAR kompenzatori, regulacijski transformatori te generatori s odgovarajućim regulacijskim mogućnostima. Na primjeru test mreže u ETAP-u prikazani su odgovarajući proračuni i analize kako bi se za neka karakteristična uklopna i pogonska stanja utvrdili osnovni principi koje je potrebno poštivati za ostvarenje efikasne i ekonomski opravdane koordinirane regulacije napona i jalove snage u prijenosnim mrežama.

Abstract (english)

Maintaining the voltage in the permitted limits with minimal loss is a very demanding task that is placed in front of the transmission system operator. This problem is further complicated with more compensating devices when effective voltage and reactive power regulation is possible in many ways. Under such conditions, special attention should be paid to coordinated voltage regulation and reactive power. In the thesis work the problem of coordinated voltage and reactive power regulation in the transmission electric power networks has been theoretically discussed. The compensating devices with which this is accomplished are described, such as Variable shunt reactor, static VAR compensators, transformers with tap changer and generators with corresponding control options. An example of a test network in the ETAP shows appropriate calculations and analyzes for some characteristic input and output states to determine the basic principles that need to be respected to achieve efficient and economically justified coordinated voltage and reactive power regulation in transmission networks.
