摘　　要：在无功补偿等应用中 ,需要检测出电网的无功量。本文阐述了无功电流幅值、无功功率、瞬时无功电流微机检测的原理与方法 ,并给出了微机检测的原理电路。它们有不同的应用场合 ,无功电流幅值和无功功率的检测适用于静止无功补偿装置 ( SVC)等方面 ,基于瞬时无功功率理论的瞬时无功电流检测适应于静止无功发生器 ( SVG)、有源电力滤波器 ( APF)In some applications as the reactive power compensation,it is necessary to detect reactive quantity.In this paper,the principles and methods of microcomputer detection for reactive current amplitude,reactive power,and instantaneous reactive current are expatiated,their principle circuits are offered.They are used to different situations,the detection for comreactive current amplitude and reactive power can be used in the static var compensator(SVC),and the microcoputer detection of instantaneous reactive current based on the theory of instantaneous reactive power will be used in the higher demand situations as the static var generator(SVG),the active power filter(APF),etc.
