NEW APPROACH ON THE STUDY OF THE STEADY-STATE AND TRANSIENT REGIMES OF THREE-PHASE INDUCTION MACHINE

Autor/autori: Alecsandru SIMION, Leonard LIVADARU, Adrian MUNTEANU

Rezumat: In aceasta lucrare sunt prezentate, pornind de la un model matematic original al masinii de inductie, rezultatele analizei unor regimuri simetrice si nesimetrice de alimentare. Sunt considerate, drept exemplu numeric, doua grade de nesimetrie, si se pune in evidenta influenta acestora asupra performantelor masinii prin simulare in Matlab/Simulink. In final, sunt trase concluzii asupra avantajelor acestui nou mod de tratare a ecuatiilor masinii asincrone.

Cuvinte cheie: masina de inductie, model mathematic in fluxuri totale, simulare Matlab/Simulink.

Abstract: Considering an original mathematical model of the induction machine, the paper presents the results of several symmetric and unbalanced regimes as concerns the supply system. As numerical example, two unbalance degrees are taken into discussion in order to point out their influence upon machine performance by means of a Matlab/Simulink analysis. Finally, conclusions on the advantages of this new approach are formulated.

Keywords: induction machine, mathematical model in total flux linkages, Matlab/Simulink analysis
