Development of 22KW experimental platform for wind power generation system using SCIG

In order to research the actual state of the wind power generation in the laboratory, a 22KW wind power generation experimental platform using SCIG was developed. The platform includes: wind simulator, L-speed gear box, back-to-back converter, filter inductor and a 10-ton platform base. The wind simulator is composed by ABB's ACS550 inverter, three-phase squirrel-cage induction motor and reduction gear box. In this paper, the current mainstream of three kinds of variable-speed constant frequency wind power generation system are compared and analyzed, highlighting the significance of the study and the basic functions of this experimental platform. Finally, the experimental results confirm that the DC-side voltage keep constantly and achieves unity power factor in grid-connected.
