摘　　要：提出了一种低压电网无功功率协同补偿方法。分别在配电变压器低压侧及380 V线路后端装设无功补偿装置,通过有规律地投切小容量电容器产生低频信号,无功补偿控制器采集并辨识该信号,从而实现线路无功补偿装置和集中无功补偿装置的协调动作,达到协同补偿的目的。A reactive power synergy compensation method of low voltage power grid is proposed.Reactive power compensation devices are installed separately at both low voltage side of distribution transformer and the backend of 380 V line.The coordination action between the line reactive power compensation device and the centralized reactive power compensation device can be realized and achieved the purpose of synergy compensation by the low frequency signals which are produced by the regular on-off switch of small capacity capacitor to produce and are collected and identified by reactive power compensation controller.

关 键 词：无功功率 协同补偿 低频信号 投切控制
