Simulation of the switched reluctance machine under single pulse mode operation

Thesis (MScEng)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: Two distinct simulation methods have been developed to simulate the single and the
multi-phase excited current waveforms of the switched reluctance machine (SRM)
under single pulse mode operation. These simulation methods are explained and
evaluated in this thesis. A non-commercial finite element package that takes the
SRM's nonlinear magnetic property into account is used in this regard. The
simulation program uses the finite element solution directly during the simulation.
Both simulation methods have been investigated in terms of result and total
simulation time. In this investigation it is shown how feasible the simulation methods
will be with the next generation of fast computers. The factors affecting the simulated
current waveforms of the SRM under single pulse mode operation are investigated in
detail in this thesis. With these factors taken into account, the measured and simulated
multi-phase current waveforms are compared with each other and discussed. / AFRIKAANSE OPSOMMING: Twee verskillende simulasie metodes is ontwikkel om die enkel- en multi-fase
stroomgolfvorms van die geskakelde reluktansiemasjien (GRM) onder
enkelpulsmodus-werking te simuleer. In hierdie tesis word hierdie simulasie metodes
verduidelik en geëvalueer. 'n Nie-kommersiële eindige element pakket wat die nielinieêre
magnetiese eienskap van die GRM in ag neem is in hierdie verband gebruik.
Die simulasie program gebruik die eindige-element oplossing direk gedurende die
simulasie. Beide simulasie metodes is ondersoek in terme van resultaat en simulasietyd.
In hierdie ondersoek word getoon hoe uitvoerbaar hierdie tipe simulasie metodes
gaan wees met die volgende hoë spoed generasie rekenaars. Die faktore wat die
gesimuleerde stroomgolfvorms van die GRM onder enkelpulsmodus-werking
beïnvloed word deeglik in hierdie tesis ondersoek. Met hierdie faktore in ag geneem
word die gemete en gesimuleerde multi-fase stroomgolfvorms met mekaar vergelyk
en bespreek.
