Abstract
This work proposes a cascaded braking mechanism. It consists of dynamic braking and yaw control scheme. Both schemes provide safety of the micro-wind turbine operation. It protects from over speed and also functioning as speed regulator. The goal of this study is to extend the lifespan of micro wind turbine by preventing it from over speed condition. The Proportional Integral Derivatives (PID) algorithm is used to control the braking mechanism based on Integral Time Absolute Error (ITAE) criteria to determine its coefficient. The proposed mechanism able to maintain rotational speed under the maximum limit when wind speed increase from 4.8-5.2 m/s without the needs to shutdown operation.
