Sensitivity and modeling analysis dynamic behaviour small wind turbine in domestic load

摘要

In this days, the necessity of using wind generators to produce energy and environmental issues, show that increasing the importance of study between researchers in this field. Since the penetration of wind power in electric power system is increasing greatly, it is urgent to study the impact of wind power on the dynamic stability of electric power system. In this paper, the dynamic behavior of the small Wind Turbine in domestic load is studied. Wind turbine induction generator connected to local load and by short transmission line that connected to an infinite bus. To achieve this goal, the simple model of small Wind turbine has been connected to an infinite bus through a short transmission line and domestic load. Using a dynamic systems model is sensitivity Analysis to changes in transmission line ratio and reactive power compensator has been studied. Finally, to investigate the eigenvalues and the locus of the system is studied. The system's modelling 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.
