摘　　要：针对煤矿供电系统电压波动严重的问题,此处将并联型有源电力滤波器(APF)应用到煤矿供电系统,并提出配流系数法对电流进行跟踪控制,从而提高了APF的补偿精度。实现了对谐波电流的准确检测与实时控制,防止了因谐波对控制设备造成干扰从而导致误操作等事故的发生。实验结果证明了该控制方法的可行性和正确性,新的跟踪控制算法能很好地满足APF对谐波电流控制的要求。For a serious problem of voltage fluctuations in coal mine power system, the shunt active power filter （APF） is studied and applied into the coal supply system, a flow coefficient of the current tracking control is presented to improve the APF compensation accuracy.The accuracy detection and real-time control of harmonic current are achieved.The malfunction and other accidents are prevented which may causing by the occurrence of harmonics due to disruption of the control device.The experimental results prove the feasibility and correctness of the control method, and the new tracking control algorithm can well meet the harmonic current control requirements.
