摘要:

针对传统统一电能质量调节器(unified power quality conditioner,UPQC)并联补偿单元信号采集精度不高、控制方法存在相间耦合的问题,采用FUZZY-PID方法对补偿信号进行检测,利用电流滞环最优矢量控制方法对并联补偿单元进行控制。将这2种方法结合来控制并联补偿单元,不仅省去矢量变换与低通滤波环节,提高了检测精度,而且通过坐标变换解决了相间耦合问题,有效提高了控制的实时性和补偿精度。最后经仿真分析和实验验证,表明了该方法的有效性和可行性。

Abstract:

 

The parallel compensation unit of traditional unified power quality conditioner (UPQC) has the problems of low signal acquisition accuracy and phase-to-phase coupling of control method. Aiming at the problems, the compensation signal detection method based on FUZZY-PID control and the current hysteresis optimal vector control method were used for parallel compensation unit. These methods can improve the detection accuracy through saving vector transformation and low-pass filter, resolve the phases coupling problem with coordinate transformation, and effectively improve the real-time performance of control and the accuracy of compensation. Finally, the feasibility and validity of the method were verified through simulation analysis and experiments.
