摘要
从稳态和动态电流跟踪两方面出发,提出了风力发电系统中PWM逆变器交流侧电感设计的新方法。为了验证所设计的电感,在MATLAB下建立了风力发电系统中的PWM逆变器数学模型,采用空间矢量脉宽调制(SVPWM)方式和电网电压定向矢量控制策略。仿真结果表明:用该方法设计的电感能满足系统的要求。从而验证该方法的可行性和正确性。
The paper presents a novel method for AC side inductance design of PWM inverer in wind power generation system, which is based on the two aspects of steady state and dynamic current tracking. In order to verify the designed inductance, the mathematical model of the PWM inverter in wind power generation system is established in MATLAB at first, furthermore, space vector pulse-width modulation （SVPWM） technology and grid voltage orientation vector control strategy are adopted. It is shown via simulation results that the designed inductance can meet the demand of the controlled system. So the feasibility and correctness of the method is verified.
