摘　　要：为解决注入式有源滤波器直流侧电能供应问题,提出一种新型注入式有源电力滤波器(APF),利用太阳能光伏发电系统给直流侧提供能量。有源滤波器的直流补偿电能来自太阳能光伏发电系统,这样不仅解决了有源滤波器的能量来源问题,且在绿色环保节能的前提下提高了电网的电能质量。采用基于坐标变换的离散傅里叶滑窗迭代谐波电流检测算法和滞环控制算法,利用Matlab进行仿真。采用TMS320F2812对主电路进行了设计,并通过实验对其性能进行了验证,结果证明该滤波器能有效补偿电流谐波。A new source of injection type active filter is proposed to solve the problem of DC power supply of injection type active power filter （APF）.The DC offset electricity of active power filter is obtained from solar energy photovohaic generation system.This not only solves the problem of energy source of active filter, but also improves power quality in the premise of green energy.The simulation model is established by Matlab and studied by using discrete fourier sliding-window iterative algorithm harmonic currents detection algorithms based on coordinates changing and hysteresis control strategy.The main circuit is designed by TMS320F2812 and the experiments of its performance is performed.lt is proved that this filter could compensate the current harmonic effectively.
