Blade Pitch Angle Regulation for H-Type Darrieus Vertical Axis Wind Turbine: A Review

Abstract

Wind energy is one of the most widely used renewable energy sources around the world. A considerable research amount was accomplished in the area of performance enhancement for H-type Darrieus VAWT using blade pitch angle regulation. This paper aims to provide a comprehensive information for future research related to performance enhancement of H-type Darrius VAWT using blade pitch angle regulation. By pointing out the current technological development, the main advantages and disadvantages of the blade pitch angle techniques used. This review discusses the main effect of fixed and variable blade pitch angle regulation, blade pitch control techniques, and mathematical modelling. The state-of-the-art on how to improve the H-type Darrieus VAWT performance by using variable pitch angle adjustment was addressed. The active variable blade pitching technique was suggested to enhance the performance of H-type Darrius VAWT as it can increase the lift force and reduce the drag force on the blade during the wind turbine operation. Additionally, DMST model was suggested to be utilized to calculate the power output as it provides relatively accurate results especially at low TSRs.
