摘　　要：为了实现对电力系统谐波的实时和精确补偿,提出了一种瞬时谐波及无功电流实时检测单相混合有源滤波器的方案,这种单相滤波器可根据用户的选择对谐波和无功电流同时进行补偿或对谐波单独进行补偿,并有LCD实时显示运行参数。对该滤波器的系统框架,控制电路,谐波检测方法,数字低通滤波等都作了较为详细的介绍。In order to achieve real-time and precise compensation of harmonic of electric power system, this paper gives a scheme of a single-phase hybrid active power filter which can measure harmonic and reactive current instantaneously. This single phase hybrid active power filter can compensate harmonic and reactive current or compensate harmonic only, which is chose by user, and LCD can timely display the work parameters. This paper detailedly introduces the frame of system, controll circuit, the detection way of harmonic and digit low pass filter and so on.
