description The rapid growth of wind turbine systems within the past two decades has been very significant within the renewable energy sector. The increasing number of wind farms has led to a driving interest in discovering new challenges and creating new technologies for these wind turbines. The aim of this project is to research both the electrical and mechanical components of a wind turbine system including the drive train and generator. A literature review was carried out to explore the fundamental equations that converts the kinetic energy of the wind to the output electrical energy that is supplied to the grid. The first section investigated was the mechanical shaft which is very important within the drive train model. It was found that stiffness and internal damping are both vital when designing the drive train shaft.
