复功率(complex power)正弦电流电路中，实部为平均功率、虚部（或负虚部）为无功功率的复数量。复功率是用相量法分析正弦电流电路时的一 个辅助计算量。
并在此基础上提出了基于严格数学推导的复功率损耗分摊方法。
The new method is based on the rigorous mathematical derivation and fully concerned about the interaction between active and reactive powers.
由于复功率追踪引入了与线路数目相等的新节点，对潮流跟踪矩阵进行求逆时将耗费大量的时间。
As complex power method introduces large number new nodes, the invert of tracing matrixes will consume a long time.
基于负荷和发电机的复功率在支路上引起的有功损耗分量，给出了负荷和发电机对元件使用份额的新定义。
Based on the branch active loss components incurred by individual loads and generators, a novel definition of the using portion of a power element by a particular load or generator is proposed.
