A comparative study on power converters for PMSG based wind turbine generation system

Abstract

This paper focuses on modeling and simulation of a Permanent Magnet Synchronous Generator (PMSG) based wind turbine with three different types of inverter with the same configuration in its control section. In this research, a Two-Level, Three-Level and a Five-Level inverter has been used in three different simulation program to justify their performance under the same control system and same PMSG system. Based on their performance, corresponding graphical analysis has also been shown. This paper also deals with the both dynamic and transient stability of the system. Proper comparison between these three inverters has been included on the basis of their simulation performance. The performance of the system is verified by proper simulations with PSCAD Professional 4.2.0 and the obtained results are presented with brief graphical analysis.
