针对双馈型风力发电机中背靠背布局的双电平三相电压型 P WM整流器中的网侧换流器,在分析其数学模型的基础上,采用设置双开关表的直接功率控制(DPC)策略,对网侧换流器进行控制,并且利用MATLAB/Simulink软件对设计的控制器进行了仿真分析。仿真结果显示,该 DPC 策略能够保证直流母线电压稳定,网侧功率因数为1,有效地控制有功功率和无功功率,使能量双向流动,具有良好的性能。

The paper focused on the direct power control of grid side converter in the back-to-back double PWM convert-er which has been used for the double-fed induction wind power generation system.On the basis of analysis of the mathe-matical model,by using the direct power control strategy with set double switch table,controlled the grid side converter. And by using MATLAB/Simulink simulation software,made simulation experiments for the design of the controller,simu-lation results showed that the control strategy can ensure the DC bus voltage stability,grid-side power factor was 1 ,and control the active and reactive power effectively,and enable two-way flow of energy,it had a good performance.
