Design, application, and power performance analyses of a micro wind turbine

Abstract

In this study, design, implementation, and power performance analyses of a micro wind turbine (MWT) system are presented. An original permanent magnet synchronous generator (PMSG) that reduced cogging torque was employed as a generator in the MWT. A novel blade form offering better performance at low wind speeds was also utilized for the MWT blades. Power performance analyses of the MWT were carried out for different wind regimes by truck testing. Performance coefficient, cut-in, and cut-out of the MWT were determined as 27.7{\%}, 2.7 m/s, and 20 m/s at the end of the truck testing, respectively. Moreover, a new supervisory control and data acquisition (SCADA) program based on a programmable logic controller was written to measure the electrical power of the MWT, and hence the analyses of the MWT were easily fulfilled through the SCADA.
