在我国煤炭生产领域，大量的大功率非线性变流装置引发谐波污染，导致整个供电系统供电质量的下降，影响煤矿生产安全。并联型有源电力滤波器已经在电网谐波治理方面显现优势。文章以三电平并联型有源电力滤波器为研究对象，采用CPT方法检测电网谐波，以重复控制和PI控制相结合的复合重复控制方法，针对电网谐波进行补偿，实验验证了控制系统的性能及稳定性。

In the field of coal production in China, large amount of high-power nonlinear converters can cause harmonic pollution, which will decline the quality of power supply system and affects the safety of coal mine production. Considering the advantages of shunt active power filter (SAPF)shown in grid harmonic suppression, this paper studies the three-level SAPF and uses conservative power theory (CPT) to detect network harmonics. The harmonics are then compensated using repetitive and PI control. Experiments verify the performance and stability of the control system.
