摘　　要：该文介绍了一种以DSP2812为主控的无功功率检测装置,采用瞬时无功功率理论,针对三相对称负载瞬时无功等同于平均无功的情况下,通过检测三相电压、电流瞬时值,实现对无功功率实时、准确地计算与检测,该文所采用的原理及算法简单易行,具有很强的工程实用性,适用于静止无功补偿装置(SVC)等需快速计算无功功率的工业控制系统。This paper presents a design of reactive power detection which uses DSP2812 as main control chip. As the case that symmetrical three phase load instantaneous reactive power equals to the average reactive power,by detecting three-phase voltage and current instantaneous value,we realized the real-timely and ac-curately calculate and detect of the reactive power with the instantaneous reactive power theory.Principles and algorithms used in this paper is simple and feasible for engineering,suitable for SVC and other reactive power industrial control systems which need quick calculation.
