Kompenzacija harmonikov v omrežju industrijskega porabnika s pomočjo aktivnega filtra

SMEŠNIK, MITJA (author), Blažič, Boštjan (mentor)

V magistrski nalogi smo se dotaknili teme o kakovosti električne energije v specifičnem industrijskem okolju. Delo obsega obdelavo osnovne tematike, kot tudi praktični prikaz izvedbe meritev kakovosti električne energije v določenem delu industrijskega omrežja za potrebe izvedbe simulacije. Meritev smo izvajali pri različnih obremenitvah, ter tako pridobili podatke za več različnih scenarijev. Sledila je obdelava podatkov ter izvedba simulacijskega omrežja v programskem paketu PSCAD. Pri izvedbi simulacije smo se osredotočili na vpliv priključitve paralelnega aktivnega filtra na bremensko zbiralko. Opazovali smo, kaj nam to prinese s stališča kakovosti električne energije. Sledilo je testiranje realnega aktivnega harmonskega filtra v transformatorski postaji. Tukaj smo s pomočjo analizatorjev moči ugotovili vpliv filtra na sistemu in pregledali njegove učinke.

Abstract

This master's degree thesis deals with electricity quality in a specific industrial enviroment. At the beginning, a review of basic topics is presented with the example of electicity quality measurement at a certain part of the industrial network for the needs of the simulation. The measurements were performed at different loads in order to obtain data for several different scenarios. Afterwards, the data processing and implementation of the simulation network in the PSCAD software package are presented. Influence of the connection of the parallel active filter to the load collector was the simulation’s focus, as well as the contribution, made to electricity quality. Lastly, testing of a real active harmonic filter in a transformer station was done. Effects of filter in the system were examined with the help of power analyzers.

• Keywords: power consumption, industrial electrical network, quality of electricity, total harmonic distortion, active harmonic filter.
