The Modelling of nonlinear dynamic behaviour of Self-Exited Induction Generator (SEIG) in Wind Turbine

Today, the necessity of using wind generators to produce energy and environmental issues, show that increasing the importance of study between researchers in this field.In this paper, after we perform Non-linear model, the Nonlinear dynamic behavior of the self-excited induction machine in wind generator has been studied.To achieve this goal, the self-excited induction generator has been connected to an infinite bus through a short transmission line. Using a dynamic systems model is sensitivity Analysis to changes in transmission line ratio has been studied. The results of the simulations show that generator speed is increased by increasing the ratio of x to r, but value of torque, after an initial transient torque is constant.The system’s modeling has been done analytically using the differential equations dominant on its behavior. The aforementioned equations have been solved using Rang-Kutta order-four method.At the end, the results of the simulation have been analyzed, and the variation of different parameters has been studied.
