摘　　要：将三相瞬时电压与三相瞬时电流分别作为电压向量与电流向量（各有三个分量），将电压与电流向量的外积运算对应的二阶反对称张量定义为瞬时无功量。本文定义表达简洁、直观，不需作任何中间变换，适合于各种三相制电路并可推广至任意相电路，具有普遍适用意义，为无功与谐波补偿理论研究打下基础。By directly taking the instantaneous 3 phase voltage and 3 phase current as two vectors with three components respectively,the instantaneous reactive quantity is defined as the outer product of votage and current vectors.Without any additional transformation,the definition can be applied to 3 phase 3 wire power systems as well as 3 phase 4 wire power systems and can be easily extended to n phase systems,so that it may be found useful in very wide fields of application.

关 键 词：三相电路 瞬时无功 无功定义
