摘　　要：根据正弦有功电流的位移电流和磁场电流与无功电流的正交关系 ,给出了正弦电流电路瞬时无功功率的实用定义 并给出非正弦周期电流电路瞬时无功功率的定义 ,由该定义得到了非正弦周期电流电路的平均无功功率的实用定义 。The definition of reactive power in sinusoidal current circuit is given by the orthogonal properties of reactive current and the removal current and electromagnetic current of active current The definition of instantaneous reactive power in nonsinusoidal periodic courrent circuit is defined also The definition of average reactive power in nonsinusoidal periodic current circuit is given from the definition of instantaneous reactive power The definition of average reactive in nonsinusoidal periodic current circuit is proved by the electromagnetic balance principle of synchronous machines

关 键 词：无功功率 谐波电流 电磁平衡 电力系统
