摘　　要：近年来矿区谐波污染日益严重,而并联电力有源滤波器(SAPF)可以对矿区进行谐波抑制与无功补偿。结合级联型多电平变换器应用于SAPF的优点,提出将分散控制策略应用于矿用级联型SAPF中,即采用上位机和下位机相结合的硬件结构。仿真实验结果表明,采用基于分散控制策略的SAPF控制系统,能使SAPF快速精准地输出谐波补偿电流指令,同时可获得很好的直流电容均压效果。The mining harmonic pollution increasingly serious in recent years. And the shunt active power filter { SAPF） can make the harmonic suppression and reactive power compensation in mining area. Combined with the advantages of multi-level cascade transformation that applied on SAPF, proposes that the decentralized control strategy applies to mining cascade SAPF, that means the hardware structure combines DSP and DSP ＋ FPEA. The simulation resuh shows that the SAPF eontrol system based on decentralized control strategy can quickly and accurately output harmonic compensation current command. And at the same time, gains good DC capacitor equalizing effect.
