Wind generation dynamic simulation connected to an electric power system

This work presents a methodology developed for dynamic wind generation simulation connected to an electric power system. It presents wind generators models and rotor excitation control strategies. The turbine mechanical power is obtained from the wind speed × time characteristic in combination with turbine power curve. The methodology has been applied to the CELPE subtransmission system connected to the CHESF system using a transient stability program StabInface© (UFCG-CELPE, 2002), implemented on this work. Two types of induction machines have been considered to model wind generators: squirrel cage and double fed induction generators (DFIG). It emphasizes voltage/reactive power control at the DFIG machines and electric power and generator terminal voltage behavior when fast wind speed variation occurs.
