摘　　要：有源电力滤波器(Active Power Filter,APF)采用定频积分控制(Unified Constant-frequency Integration Control,UCIC)摆脱了先检测无功电流,然后根据检测信号产生补偿电流的传统控制方法,简化了APF结构,降低了成本。实验证明,采用该方法的三相三线AFP可有效消除谐波,提高功率因数并可补偿供电点的电压波动。Active Power Filter （APF） with Unified Constant-frequency Integration Control （UCIC） make itself get rid of the traditional control method of sensing harmonics and reactive current components and generating compensating currnts according to signals sensed.It simplifies the structure of APF and makes it cost less.It is supported by experiments that three-phase three-wire APF with unified constant-frequency control is a viable solution to mitigate the harmonics and improve the power factor and abate the instability of power supply point.
