Electromagnetic Transients of a Micro-Turbine Based Distributed Generation System

Abstract-This paper evaluates the electromagnetic transients of a micro-turbine based distributed generation system that includes an AC-DC-AC converter. An outline of modelling the micro-turbine based generation system including the AC-DC-AC converter is presented. A controller for the converter, that consists of a number of single-input single-output sub-controllers, is designed based on the developed model of the system. Furthermore, the thermodynamic model of micro-turbine system is presented. The electromagnetic transients of the overall micro-turbine based generation system including the micro-turbine and converter controllers are evaluated based on time-domain simulation studies in the PSCAD/EMTDC software environment. The study considers the dynamic models of generator, converter and power system and the thermodynamic model of micro-turbine system
