摘要: This work demonstrates that the integration of variable-speed wind systems with doubly fed induction generators (DFIG) and a four-quadrant AC-to-AC converter connected to rotor windings increases transient stability margin electrical grids, when compared case where fixed speed cage are used. It is due influence two dedicated current regulators DFIG on dynamic behavior other in system. Besides, adequate models represent studies presented. From simulation results, some important conclusions can be extracted guide farms weak or strong grids.
