| Abstract: | The double-fed induction wind generator (DFIG) has paid a large portion of the windturbine generator in the electrical power system at present. This paper analyzed the powercharacteristics and the method of maximum wind energy tracking based on the mathematical modelof the DFIG and the decoupling control of active and reactive power. Taking the parameters of 2MWDFIG for example, the simulation model is developed using PSCAD/EMTDC based on thestator-flux-oriented vector control method. Using the action of a variable-pitch control and the activepower control to control the rotate speed indirectly and to get a maximum power. The results ofsimulation prove the feasibility presented in this thesis. |
