并联型有源电力滤波器的研究
|
摘要
为了抑制电力系统中由于大量使用电力电子器件而带来的谐波干扰,研究了并联型有源电力滤波器(APF),对其系统结构和工作原理进行了分析,并介绍了利用小波分析法进行谐波监测的原理,建立APF系统的数学模型,最终搭建了并联型有源电力滤波器并网运行的仿真模型。仿真结果表明,并联型有源电力滤波器能够在不影响电流基波频率的情况下,补偿系统谐波,消除谐波带来的危害。
In order to suppress the harmonic interference resulted from the large number of power electronic devices usage in power systems, a shunt active power filter is studied. Its system structure and working principle are analyzed, and the wavelet analysis method is used to monitor the harmonic. A mathematical model of APF system is established. Finally, a simulation model for the parallel-operated shunt active power filter is built. The simulation results show that the shunt active power filter can compensate the system harmonic, and eliminate the harm resulted from the harmonic without the affection of current fundamental frequency.
