| Abstract: | On the basis of the analyzing output power of wind turbine and the operation characteristics of DFIG, a decoupling control method of the active and reactive power of DFIG based on the maximum wind energy tracking is proposed, by means of analyzing the specific process of controlling the rotor speed of DFIG to track maximum wind energy. Then, a control system model for tracking the maximum wind energy based on a stator flux-oriented vector control is built, the simulation of which is carried out with PSCAD/EMTDC. The results have verified the feasibility of the control strategy. |
