Generiranje visokofrekvenčnih komponent navora z električnimi pogoni

DRNOVŠČEK, JERNEJ (author), Nemec, Mitja (mentor)

V tej nalogi so raziskane meje generiranja visokofrekvenčnih komponent na- vora z električnimi pogoni. V prvem delu naloge je teoretična meja generiranja visokofrekvenčnih kom- ponent navora raziskana na sistemu enosmernega stroja. Najprej je meja ge- neriranja visokofrekvenčnih komponent navora določena matematično, nato pa potrjena s simulacijo. Na koncu prvega dela je še prikazan vpliv regulacije s proporcionalno-integrirnim regulatorjem na mejo generiranja visokofrekvenčnih komponent navora. V drugem delu naloge je teorija sistema enosmernega stroja prenesena na sistem regulacije visokofrekvenčnih komponent navora pri stroju s trajnimi ma- gneti. Prav tako so tudi tukaj izvedene simulacije, ki potrdijo izpeljavo na sistemu s PMSM strojem. V zadnjem delu naloge so izvedene simulacije in meritve na sistemu s PMSM strojem z namenom vrednotenja simulacijskih in eksperimentalnih podatkov. Re- zultati so pokazali, da lahko z izpeljano teorijo razmeroma dobro ocenimo mejo generiranja visokofrekvenčnih komponent stroja. Pri obravnavanih strojih je navor neposredno odvisen od toka. Zato so meje generiranja visokofrekvenčnih komponent najprej izpeljane za tok, nato pa je narejena pretvorba v navor.

• Title: Generation of high-frequency torque components with electrical drives

Abstract

In this master's thesis, the limits of generating high-harmonic torque compo- nents at electric machines have been studied. Within the first part of the thesis the theoretical limit of generating high fre- quency torque components is studied on the system with DC electric machine. Firstly, the limit of generating high-harmonic torque components is mathemati- cally determined, and then conrmed by the simulation. At the end of the first part, the influence of the proportional-integral controller on the limit of genera- ting high-harmonic torque components is also shown. In second part the theory of generating high-torque components is transfer- red to the system with permanent magnet synhronus machine (PMSM). This is followed by simulations which confirm the theory of generating high-harmonics torque components in system with PMSM electric machine. In the last part of this master's thesis, simulations and measurements were made on a system with PMSM machine. The main purpose of measurments were evaluating theoretical and simulation results. The results showed, that with this theory we can determine the limit of generating high-harmonic components torque of the machine relatively well.
