摘　　要：石化企业中产生的无功电流是电网功率因素降低重要原因之一,静止式无功发生器(SVG)是一种新型重要的补偿无功电流装置,在SVG系统中,无功电流的检测是决定无功补偿效果以及速度前提。本文设计了一种无功电流检测系统,该系统可以检测三相电网电流,三相电网电压,最后通过基于DSP控制器计算出三相电网的无功电流,进而为实现SVG补偿无功电流提供关键依据。The reactive current generated in petrochemical enterprises is one of the important reasons for the power factor reduction of the power grid.Static var generator(SVG)is a new important device for compensating reactive current.In SVG system,the detection of reactive current is the precondition to determine the effect and speed of reactive compensation.In this paper,a reactive current detection system is designed,which can detect the current and voltage of three-phase power grid.Finally,reactive current of three-phase power grid is calculated based on DSP controller,which provides a key basis for SVG to compensate reactive current.
