Synchronous control of connecting AC-Excited doubly-fed wind power generator to the grid

Running principle of the grid-connection synchronous control of AC-Excited variable-speed constant-frequency (VSCF) wind power generator was discussed. Grid-connection control strategy of generator was investigated based on stator field-oriented vector control technique. The simulation model of grid-connection process of AC-Excited VSCF wind power generator was founded. The simulation result verified the validity and feasibility of the grid-connection synchronous control in this paper.
