The VSCF generator interconnection under Stator-flux-oriented vector control

With the increase in the energy problems, new energy resources, such as wind power, are seriously focused on. The interconnection technology of double-fed induction generator (DFIG), which is used in wind power generation, has turned into an important part. The stator-flux-oriented vector control principle is applied to build a model of the typical DFIG in dq synchronous revolution coordinate system, and the PSCAD/EMTDC simulation software is employed to research the interconnection control method, furthermore, the double loops control strategy is adopted. The application of the separating integral PI control can eliminate the system oscillation and can smooth the start course. The simulation results show that the stator-flux-oriented vector control is an effective method that aims at the interconnection of the DFIG.
