Performance Evaluation and Validation of H-Darrieus Small Vertical Axis Wind Turbine

초록

In this study, the power performance of an H-Darrieus vertical-axis lift-type wind turbine is investigated. Computational fluid dynamics and double-multiple stream tube simulations are used to predict the power coefficient (aerodynamic efficiency) of the rotor. Additionally, the efficiency of the electrical systems, including the generator and the inverter, is experimentally investigated by a motor-generator test. Finally, the power curve of the wind turbine is predicted by combining the performances of the rotor and the electrical systems, and the power curve prediction is experimentally validated by a field test. As a result, the maximum error in the electrical power output was found to be 8.92% at 6.0 m/s.
