分析无功补偿装置中并联电容器对系统谐波电流放大的影响，提出有源电力滤波器与无功补偿装置并联使用时采样点(有源电力滤波器电流互感器CT的安装位置)的选取方法，并以某机场助航灯光站谐波治理项目为例进行说明。%Sampling points (mounting positions of the current transformer in the active power filter) selection for the active power filter in parallel with the reactive compensation device are put forward upon the analysis on the impact of shunt capacitors in the reactive compensation device on the system harmonic current amplification, and the harmonic treatment project of navaid lighting station in certain airport is taken as an example for illustration.
