Besides the wind speed, the blades’ angle in the wind turbine can also affect the rotational speed. Therefore, in order to automatically adjust the angle of the blade, it needs to be equipped with a pendulum. This, research aims to design and test the rotational speed of wind turbines using a pendulum, which is positioned at a certain radius to the turbine shaft (X-axis) for the speed sensor’s sensitivity and to provide a torsional force on the blade edge of (Y-axis). Furthermore, a wind turbine prototype equipped with a pendulum is designed based on the angular curve’s characteristic, which comes to changes in wind speed. The test results show that controlling the rotational speed using a pendulum at a specific position can work quite effectively, irrespective of its ability to provide a completely constant speed. © 2020.
