Vector Control and Direct Power Control of Wind Energy Conversion System based on a DFIG

摘要

The paper present the modeling and controlof 1.5 MW wind energy conversion system (WECS)equipped with a DFIG for a variable speed. Abidirectional converter is employed for the powerconversion exchanged between the machine stator andgrid. The control strategy of DFIG and rotor sideconverter (RSC) combines the technique of MPPTincluded the control of the generator speed byProportional Integral (PI) and vector control (VC). Inthe control system of the grid side converter (GSC) theapplication of direct power control (DPC) has beenused. The results of simulation of the global controlsystem have been presented and discussed.
