摘要：
According to the characteristic of AC-excited variable speed constant frequency wind turbine, a grid voltage orientation vector control strategy is used for doubly-fed induction generator (DFIG). Firstly, this paper studies the running characters of DFIG, and the principle of DFIG under no-load cutting-in condition. Then according to the mathematical model of DFIG under no-load cutting-in condition, this paper proposes a higher-order sliding mode control for the model. Finally, a comprehensive system simulation on the no-load operation is carried out and the following situations are studied: before cutting-in, the transient process at the cutting-in moment and the DFIG tracks the maximum wind energy after cutting-in. The simulation results validate the proposed method. © 2012 State Grid Electric Power Research Institute Press.
