Design and Modelling of Induction GeneratorWind power Systems by usingMATLAB/S IMULINK

[摘要] This paper describes the performance comparison of a wind power systems based on three different induction generators. The three induction machines studied for the comparison are the squirrel-cage induction generator (SCIG), the doubly fed induction generator (DFIG) and using a doubly fed induction generator in single-sided grid connection. The performances are compared between the SCIG, DFIG and DFIG in single-sided grid connection systems. The SEF-DFIG stator of the machine is connected with a direct power grid, and the rotor is controlled by an inverter without any external power source.
