交流电功率

交流电力系统中各个与功率相关的参数在复平面内的表示
The blinking of non-incandescent city lights is shown in this motion-blurred long exposure. The AC nature of the mains power is revealed by the dashed appearance of the traces of moving lights.
  Phase of current, φ
Transformateur électrique d'une puissance apparente de 100 kVA.

电路中的功率指的是能量通过电路中一点的速率。在交流电力系统中,例如电感器和电容器之类的储能装置可能会导致能量流动方向的周期性变化。在一个完整周期内,能量在一个方向上的净流动率称为有功功率,而由储能装置返回电源的部分称为无功功率

Power in an electric circuit is the rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. The portion of power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as active power (sometimes also called real power). The portion of power due to stored energy, which returns to the source in each cycle, is known as reactive power.
