Abstract

In small-scale wind turbines various types of control mechanisms are used to protect them from high wind speeds, i.e. when the wind speed exceeds the rated value. In tilted up type small-scale wind turbines the rotor is free to move around horizontal as well as vertical axes. Therefore when the wind speed exceeds the rated value the rotor tilts upwards and sideways and comes to a stable position with an inclination to the direction of wind and hence controlling the component of the wind responsible for power generation (and for the rotational speed of the rotor). This paper describes, how a mathematical model is developed by using D' Alambert's principle to investigate the complex behavior of the wind turbine during the transient period and the stable position.
