摘要
本文着重论述了基于电压检测的并联型有源滤波器在放射状配电网谐波抑制中的应用及其安装点的选择。对外电路而言 ,在基波频率下有源滤波器被控制为无限大阻抗 ,在谐波频率下被控制为小电阻。实验结果证明 ,将有源滤波器安装在放射状配电网的末端母线上 ,可在整个配电网上有效地抑制谐波。
This paper is focused on a shunt active filter based on detection of harmonic voltage to attenuate harmonic propagation in a power distribution network and its installation site selection. The active filter acts as an infinite impedance to the external for the fundamental frequency and as a low resistor for harmonic frequencies. Experimental results show that if the active filter is installed on the end bus of the radial power distribution line, it successfully performs harmonic damping throughout the distribution line.
