High-order Sliding Mode Control for No-load Cutting-in of DFIG Wind Turbines
摘要
Abstract
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.关键词
