摘要：

This paper covers a scheme of variable speed constant frequency (VSCF) wind power generation system. Several methods of collecting the wind power are compared. The VSCF wind power generation system composed of PMSM is studied in detail. Then the three-phase 4-quadrent converter that connects the generator and power line is discussed in detail. IGBT is chosen as the power electronics element. The topology and energy flow of the inverter is given. Working principle of acquire unity power factor is studied also. Using state-space averaging model, small inertia current tracking (SICT) control is explained in detail. The system is controlled by digital signal processor using SICT method. Finally, experiment result is given, which prove this scheme can send the energy into power line with high power factor.
