Variable Pitch Control In VAWT

A variable pitch, vertical axis wind turbine is being studied. The project aims to improve the self-starting capability of the turbine by implementing a dynamic-variable blade angle control system. A simulation and analytical study indicated that there is an optimum setting of the rotor blades that produces a maximum torque that improves the starting characteristics of the turbine.

Another goal of the project is to improve the efficiency of the turbine at different rotational speeds through dynamic pitch angle control. This is done through developing a correlation between the rotor torque, rotor instantaneous position, blades pitch and wind direction that results in maximum aerodynamic rotor power under various operating conditions. Another addition to the study was inputting the approaching wind direction. With this technology, we will be able to enhance the efficiency of all VAWT and allow for a greener and more eco-friendly power-generating source through the wind.
