Abstract
Wind speed changes drastically with a very fast interval makes windmill requires a control system that aims to prevent damage due to excess wind energy. Furling mechanism works by utilizing aerodynamic forces and gravity. This simple system is realistic to apply to micro-scale wind turbines.
In this study was designed to make windmills protection at a wind speed of 8 m/s. Experiment carried out using a car as means to manipulate the wind speed. Wind speed is measured using anemometer and furling movement data recorded using the camera. Video footage are combined using Camtasia Studio application to synchronize the data the furling angle, blades revolution and wind speed data. Angle analysis performed by image analysis results of screenshots every change of wind speed by a margin of 0.5 m / s are then measuring the angle using Autodesk Inventor application.
The experiment results show that the furling design has approached the desired criteria. Windmill began to yaw at a wind speed of 7.5 m/s which is slightly lower than the initial plan 8 m/s. At a wind speed of 7.5 m/s have been formed 1,5o yawing angle and the angle of furling 1,5o with blade speed of 720 rpm. Furling mechanism design managed to hold the rate hike of blade rotation at 1007 rpm by yawing angle of 37o and furling 16o at a wind speed of 9.5 m/s. As the increase in wind speed, yawing and furling angle formed increasingly large and blade speed decreases.
