Načrtovanje kompenzacije jalove moči v transformatorski postaji

GLAVAN, MATEVŽ (author), Blažič, Boštjan (mentor)

V diplomskem delu sem se osredotočil na temo načrtovanja kompenzacije jalove moči v transformatorski postaji. Potrebna je bila prenova kompenzacijskih naprav v določeni transformatorski postaji, v podjetju Revoz v Novem mestu. V omenjenem podjetju, kjer sem opravljal tudi praktično usposabljanje, mi je bila zaupana analiza preureditve kompenzacije v transformatorski postaji 10. V prvem delu diplomske naloge sem teoretično opisal jalovo moč ter kompenzacijo le te. Opisal sem tudi vrste kompenzacijskih naprav, ki se uporabljajo za namen kompenzacije. Posebno poglavje sem namenil škodljivim harmonskim komponentam in opisu poti električne energije od njenega izvora do transformatorske postaje same. V drugem delu diplomskega dela sem se osredotočil na specifično transformatorsko postajo. Naštel in opisal sem elemente, ki se nahajajo znotraj samega objekta. Predstavil sem tudi dve vrsti meritev, ki so bile opravljene na kondenzatorjih in na sekundarnem navitju transformatorja. S pomočjo teh sem prišel do končnih ugotovitev in do predloga za preureditev kompenzacijske naprave.

• Title: Reactive power compensation planning in a secondary substation

Abstract

This diploma thesis focuses on the planning procedures for compensation of reactive power in electrical substation. In specific substation, in factory Revoz renovation of compensation devices was required. In the mentioned factory, where I also did a student work, I was trusted to study an analysis of renovation of compensation of reactive power in substation 10. In the first part of diploma, I theoretically described reactive power and it's compensation. I also described types of compensation devices, which are used for the compensation of reactive power. In the special chapters I described harmonic components and transfer of electrical energy from it's power source to substation itself. In the second part of diploma I was focusing on a specific substation. I described electric components and parts inside of facility. I presented two different types of measurements, which were taken on capacitators and a secondary winding of transformer. Based on the measurments, I came to the final conclusions and to the proposal for the compensation device renovation.
