Abstract:The Direct-driven variable speed constant frequency (VSCF) wind generation system takes low speed PM generator as the generator ,and it has the advantage of no gearbox ,low mechanical loss, high efficiency, low maintenance cost. So it has been paid more an more attention. The topology of the Direct-driven variable speed constant frequency (VSCF) wind generation system is analysed, the SCR converter, voltage resource inverter are compared, current resource inverter, and points out the advantage and disadvantage of each topology.
Keywords:direct-driven  variable speed constant frequency (VSCF)  gearbox  converter  PMSM  full scale converter
