摘　　要：煤矿井中起重机等大型设备的接入,给谐波补偿带来了困难。有源调谐滤波器可以准确有效地补偿电网谐波电流。对有源调谐型混合滤波器的失谐度检测环节和补偿系数跟踪环节进行改进,从而更好地优化矿区的电能质量。搭建了系统仿真模型,仿真结果表明改进后的算法可以很好地实现对电网谐波电流的补偿。The access of large equipment such as crane in coal mine brings difficulties to harmonic compensation. The active tuned filter can compensate the harmonic current of the power system accurately and effectively. The active tuned hybrid filter detuning detection and tracking of compensation coefficient is improved to optimize the power quality better in the mine area. The simulation system model is built,and the simulation results show that the improved algorithm can realize the harmonic current compensation well.
