A linear dynamic model for asynchronous wind turbines with mechanical fluctuations

In this paper, a specific linear dynamic model for an asynchronous machine is presented. This model is based on the balanced dynamic model of the asynchronous machine and it is developed for asynchronous wind turbines when the mechanical power (wind power) has sinusoidal fluctuations. The dynamic and the proposed linear models for real and reactive powers and voltage fluctuations analysis are considered and compared.
