Novel method of wind energy conversion system by incorporating permanent magnet generator and single stage AC-AC power converter

Abstract

This study proposed a cost effective method of wind energy conversion system (WECS) incorporating permanent magnet generator (PMG) and single stage power converter. Axial flux PMG can generate rated voltage and frequency even at a lower speed and hence more suitable for direct drive WECS. To get desired voltage and frequency in continuously varying wind conditions, a new type of WECS with single stage power conversion is being proposed. Matrix converter in the system is mainly used to control output voltage and frequency. It also reduces size of the system and cost of power generation.
