High efficiency drive for micro-turbine generator based on current phase and revolving speed optimization

Abstract

This paper presents a high efficiency drive strategy for the micro-turbine generator (MTG) in which the permanent magnet synchronous generator (PMSG) is employed. The PMSG operates with maximum efficiency by optimizing the decomposition of the dq-xes armature currents in the synchronous reference frame. In addition, in order to effectively use the turbine output power, compressor optimizing the revolving speed of the PMSG minimizes input power. Simulation results confirm the validity of the proposed method.
