Modeling, simulation and experimental test of a variable-speed cage machine wind generation system

As the cost of power electronics and control is decreasing, the squirrel-cage induction generator with back-to-back power converters is becoming popular among the variable-speed wind turbines. This paper describes a complete simulation study of a VSWT (variable-speed wind turbine) system based on squirrel-cage induction generator. It includes the modeling of a wind turbine, generator, and a double-sided PWM converter with real power and reactive power control. The validity of the simulation and the modeling of the system are verified by a real-time wind turbine generation system test bed.
