Abstract

This paper targets to the challenge of electrical energy production and energy efficiency by studying synchronous reluctance machines (SynRM), as an alternative to permanent magnet generator in electric power generation with focus in renewable energy applications. Considering the SynRM as a special case of the wound-rotor synchronous generator, this paper explores the operating limits of the machine and proposes a control strategy to operate a SynRM in an extended speed range while reducing cooper loses. Numerical simulation is used to demonstrate the feasibility of this solution and to validate the analysis.
