2013 (English)In: Proceedings of the 10th Jubilee International Symposium on Advanced Electromechanical Motion Systems: ELECTROMOTION 2013 Cluj-Napoca, Romania, October 21-22, 2013, 2013, Vol. 20, 138-144 p.Conference paper (Refereed)
A novel speed control strategy of an inductionmachine with RPEC (rotating power electronic converter) isinvestigated in this paper. The stator of the machine is directlyconnected to the power distribution network while the open-endedrotor windings are connected to a back-to-back converter. Adynamic model is developed in the three-phase reference frame.Dynamic performance of the starting process of the system isstudied, based on an 1.8kW induction machine in the laboratory.Experimental results have shown that constant speed control isachieved in a simple manner by controlling the rotor currentfrequency. Importantly the stator power factor can be improvedeffectively within a wide range of load variation including therated load. Moreover, the dc-link voltage over the capacitorbetween the two converters is considerably low which implies agreat reduction of the capacitor size.
