| 摘 要： | 实验发现,使用铁芯电抗器的三相四线制并联型有源电力滤波器(Parallel Active Power Filter,PAPF )投入后系统电流偶次谐波增幅明显,以2次谐波增幅最大.本文对此现象进行了详细的理论分析,并在MATLAB环境下进行了有无直流偏磁情况下的仿真.仿真和实验结果表明,铁芯电抗器直流偏磁是产生偶次谐波的主因,进而影响到PAPF的滤波性能.该结论对PAPF的实际工程应用设计具有一定的指导意义.

| Abstract: | Through the experiments,it is found that when three-phase four-wire parallel active power filter(PAPF) using iron-core reactor is connected to power grid,even-order harmonic system current increases significantly,especially second-order harmonic increases largest.This phenomenon is expressed in detail by theoretical analysis and has been simulated under MATLAB environment,with or without DC bias.Simulation and experimental results show that iron-core reactor generating DC bias is the main cause of even-orde... |
