With the single unit capacity of wind power is increasing, the grid-connection impact current can't be neglected now, that the grid-connection control technology should be had an in-depth study. In this paper the vector control based on the stator flux-oriented is transplanted to the grid-connection control, the no-lode grid-connection control strategies of AC excitation wind power generator is established,...
Aimed at the application of directly driven PMSG (Permanent Magnet Synchronous Generator) in MW wind power system, a strategy of compound vector control with the orientation at the direction of stator current is proposed in this paper. This strategy adopts the MTCRC (Maximum Torque / Current Ratio Control) mode to perform normal power generation within the range between the cut-in speed and a turning...
