| 摘 要： | 通过建立应用于恒频变速风力发电系统的三相电压源型PWM变换器在两相旋转坐标系下的数学模型,针对三相电压源型PWM变换器输出电压响应慢的缺点,本文采用电压电流双闭环控制的网侧变换器及空间电压矢量SVPWM调制方式,在Matlab/Simulink中进行了系统建模和仿真研究。仿真结果表明,该控制策略能够快速调节直流侧电压达到稳定,能够控制输入电流波形及相位,验证了该控制策略的可行性。

| Abstract: | Mathematical model of converter on three-phase voltage source PWM used by variable-speed constant-frequency doubly-fed wind power generator under two-phase rotation coordinate system is established.In view of the three-phase voltage source PWM converter output voltage responsing slowly,this article provided the system model and simulated in Matlab/Simulink using nets-side converter of voltage current double closed loop control and space voltage vector SVPWM modulation mode.The simulation results show that the control strategy can regulate direct current side voltage to achieve stability and can control the input current waveform and phase,which verifies the feasibility of the control strategy. |
