Measurement and Performance Evaluation of Horizontal Axis Wind Turbine Using Variable Blade Pitch Control Mechanism
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 12
Abstract
This work investigates the performance of a horizontal axis wind turbine (HAWT) with variable blade pitch control mechanism. The control mechanism is a simple mechanical Watt governor design, which was developed to regulate the blade pitch angle of the HAWT. This depends on the magnitude of the wind speed that will be subjected to the turbine. A scale down of 1:10 blade geometry as designed and developed by the Author's previous work was used for the HAWT model. The HAWT model performance was tested in a wind tunnel that was developed specifically in order to carry out the experimental test. Parameters measured are the generator output voltage and rotor speed, which were based on the wind speed that was also regulated accordingly. The experimental test carried out shows that between cut-in and cut-out wind speed of 2 and 4 m/s, both the generator output, voltage and rotor speed increases with increase in wind speed. But as the wind speed increases beyond the cut-out wind speed generator output voltage and the rotor speed, there was stability and constant values were observed up to the ultimate wind speed of 6 m/s and subsequently there was a shutdown. This tested performance predicts that the variable blade pitch control mechanism will regulate and bring the require control of HAWT under high wind speeds.
