Hysteresis Controller Based PFC Controlled Three Phase Vienna Rectifier for PMSG Fed Wind Energy Conversion Systems

This paper presents a hysteresis current controller (HCC) for a three-phase Vienna rectifier integrated with Power Factor Correction (PFC), specifically designed for Wind Energy Conversion Systems (WECS) utilizing Permanent Magnet Synchronous Generators (PMSG). The primary objective is to enhance the efficiency and reliability of wind energy conversion. The proposed control strategy employs hysteresis modulation to regulate the rectifier’s output, ensuring high power quality and minimal harmonic distortion. The Vienna rectifier enables reduced component count and improved thermal performance compared to conventional rectifiers. PMSG serves as a stable energy source, adapting efficiently to variable wind speeds. Simulation results demonstrate the effectiveness of the HCC in maintaining system stability across different wind and load conditions. The study also assesses the system’s dynamic behavior, efficiency, and practical performance. Furthermore, a PMSG-based wind turbine model is implemented, and the results validate the performance of the proposed topology, achieving Total Harmonic Distortion (THD) values of approximately 1.51%, 1.52%, and 1.53% under three-phase grid conditions. This research contributes to advancing renewable energy integration and addressing the challenges of wind energy conversion and grid connectivity.
