| 摘 要： | 直驱式风力发电系统中的电压型整流器采用磁链定向取代电压定向方式,不需要电压传感器采集电压信号,可以降低变流器成本。构建了基于Matlab/Simulink仿真环境的无电压传感器磁链定向空间矢量脉宽调制(SVPWM)整流的仿真模型,验证了该方法可正确确定矢量定向角度,实现单位功率因数整流,有功和无功解耦控制以及直流侧的电压稳定。

| Abstract: | In direct-drive wind power system,flux oriented vector is applied instead of line voltage oriented vector,which can eliminate the line voltage sensors and reduce the costs of PWM rectifier.A simulation model of the voltage sensor-less flux oriented vector control of PWM rectifier has been established based on Simulink in Matlab.The simulation results show that the control scheme can orient correctly,realizing unity power factor,decoupling the active and reactive power and maintaining the steady of the DC vo... |
