通过分析网侧变换器和定子侧变换器运行原理,提出变换器的数学模型和控制策略,利用定子磁链定向矢量控制方法和电网电压定向的矢量控制方法,建立矢量控制方程式,采用双闭环控制策略实现定子有功功率、无功功率的解耦控制,使得网侧保持功率因数运行和直流母线电压稳定.通过MAT-LAB/SIMULINK软件,构建了风电系统仿真模型,仿真结果验证了矢量控制的可行性.%By analyzing the operation principle of net side converter and stator side converter, the converter' s mathematical model and control strategy were put forward, including the vector control equations established by using stator flux orientation vector control methods and the network voltage orientation vector control methods and a double-closed loop control strategy to make the rotor stator active power and the reactive power decoupling so that the Networks side can keep power factor operation and the DC bus voltage stability; the Mat-lab/Simulink-assisted simulation model verifies the feasibility of the vector control.
