Research on Maximum Wind Energy Tracking For VSCF Doubly-Fed Wind Power System
The operation principle of doubly-fed induction generator and the power characteristics of the wind turbine are analyzed,the control strategy of maximum wind energy tracking is discussed in detail,then the simulation model of doubly-fed wind power system is established based on stator flux orientation vector control strategy,taking two step-up wind speeds as example,simulation research is made on the operation characteristics of the model.The simulation results demonstrate that the model realizes the maximum wind energy tracking and variable-speed constant-frequency(VSCF) operation.At the same time,the simulation confirms the correctness of the model and the control strategy.
