مدل سازی و کنترل توربین بادی با سرعت متغیر مبتنی بر ژنراتور القایی دو سو تغذیه

This paper presents a modeling and a control of doubly fed induction-generator (DFIG)-based variable-speed wind-turbine. A detail dynamic model of a DFIG-based wind-turbine grid-connected system is presented in the dq-synchronous reference frame. Along with conventional control schemes for wind turbine, an innovative voltage control scheme is proposed that manipulates dynamically the reactive power from the voltage-source converter (VSC) with taking into account its operating state and limits.
