摘要 在正弦情况下,电路的有功功率、无功功率都有合理的定义,在非正弦情况下,有功功率有了合理的定义,但无功功率的定义一直没有定论.由于电力电子装置和设备在电力系统中的日益广泛的应用引起电网的污染和设备的利用率降低,传统的无功功率的计算方法无法计算非正弦波时的无功功率.本文论述了广义无功功率的定义及计算方法。 The active power and reactive power of sine alternate current have reasonable definition. The active power has a reasonable definition in a nonsinusoidal alternate current, but the reactive power has not. The increasing extensive applied electric and electronic equipments in the electric power net have made the net pollution and lower utilization of the equipments. This makes no traditional method can work out the reactive power in a nonsinusoidal alternate circuit. In this paper we discussed the definition and calculation methods of the extensive reactive power.
