摘　　要：谐波电流检测是谐波治理的关键技术之一,传统的谐波电流检测法虽然适用于电压有畸变的情况,在电压不对称的情况下会有误差。针对此问题,将选频带通滤波器与基于广义积分器的正序分量计算法相结合,并基于p^q理论设计APF的参考电流提取计算方法。在电流滞环比较控制下,通过仿真验证,基于选频带通滤波器和基于广义积分带通滤波器参考电流检测法的有源电力滤波器具有良好的的谐波补偿效果。The detections of harmonic current in urban rail transit is one of critical techniques for the control of harmonic current. The traditional harmonic current detection method is applicable for situations with voltage distortion, but there is error in the case of asymmetric voltage. To solve this problem, in this paper selective band pass filter is combined with generalized integrator based positive sequence calculator, and reference current extraction is designed based on P-Q theory. Under the current hysteresis comparison control and through simulations, the active power filter reference current extraction which based on frequency band pass filter and generalized integrator based positive sequence calculator has good effect on harmonic compensation.
