Design of Rigid Body Dynamics for Pitch Regulation Mechanism to Maximize Energy Capture by Wind Turbine

Abstract

Wind turbines are generally designed for specific wind speeds and at below or above these speeds wind turbine could not give the expected maximum power. To obtain the maximum power at different wind speeds, pitching mechanism of the blades introduced. Mostly active pitching is used on large scale but the study gives detail advantages, design and analysis of passive pitching which is free of electronics. The study suggested the design that through centrifugal masses the rotor is able to changes the pitch angles through 10 degrees which are enough for wind speed ranges from 4-20 m/s which maintain the optimum angle of attack maximizing the power output. This report includes an in- depth analysis of design process, detailed components and assembly, recommendations, and conclusions.
