ROTOR ANGLE WIND TURBINE ENERGY CAPTURE CONTROL

In wind turbines the power generation (power capture) and output torque depends on wind speed. Due to the rapid variations in wind speed, wind and inflow angle evaluating the output power becomes a challenging problem. Many optimization control techniques seek to extract the output power continuously. This paper focusses on dynamic analysis and control of variable wind turbine's rotor yaw angle and angular deflection. Earlier work used wind direction and pitch angle to control the performance of wind turbine. Using rotor yaw and angular deflection control of horizontal and vertical axis wind turbines is relatively new. For dynamic analysis, rotor yaw and rotor angular deflection, model techniques and experimental setup mechanisms were done in detail. Simulations were carried out in C++ to program an Arduino microcontroller and motor driver. Matlab software was used to interface wind turbine experimental setup, Arduino microcontroller and show the functions and aerodynamic forces. The result shows that the performance of wind turbine with this technique gives better result by increasing the power capture by about 15% more.
