Analysis, Modeling and Control of Doubly-Fed Induction ...

2007-2-4  driven synchronous generator (without gearbox) or a doubly-fed induction generator (DFIG). Fixed-speed induction generators with stall control are regarded as unfeasible [3] for these large wind turbines. Today, doubly-fed induction generators are commonly used by the wind turbine industry (year 2005) for larger wind turbines [19, 29, 73, 105].
