https://techjournals.stmjournals.in/index.php/JoAET/article/view/1470
<p><em>The wind energy system (WES) has been gaining popularity in recent years for the reason of its resourcefulness and intrinsic reproducibility. Power quality and transient stability are major issues of WES under the influence of fluctuating wind speeds and network outages. The study focuses primarily on the various drive train models for the DFIG wind turbine, as well as torsional oscillations produced fluctuations in wind speed. The pitch-damping control is implemented to decrease the torsional oscillations and hence lowering system damage. A double fed induction generator is utilized in wind turbines because they can produce efficient power at varying rotor speeds. This paper primarily defines the various drive train models, which include six–mass model, four–mass model, three–mass model, two-mass model, and one-mass model. Also, the torsional oscillations are caused by the variation in the wind speed. The system gets excited when subjected to variations in the wind speed resulting in spatial fluctuations in the terminal voltage of the system. To mitigate these oscillations, either using a pitch controller or inverter to regulate the speed of the wind turbine. These oscillations can be damped in two ways. The first is by using a pitch controller and the second is by controlling the torque.</em></p>Peddada Sandhya RaniNalli Akhil BabuT. R. Jyothsna
