| 摘 要： | 虽然在非正弦情况下电压，电流，有功功率都得到了合理的定义，但无功功率的定义一直没有定论，本文研究和分析了非正弦情况下功功率定义两种方法，一种是时域分析法，另一种是频域分析法，深入探讨了两种定义的优缺点；最后指出，应在不同的条件下，根据不同的任务，来选择合适的公式进行分析计算。

| Abstract: | Although voltage,current and active pow er are reasonably defined in nonsinu-soidal conditions,reactive power is still q uestionable.In this paper two methods which are used are studied and analyzed to define reactive power in nonsinusoidal conditions,one is the time domain an alysis method,the other is frequency domain analysis method.Their ad-vantages and drawbacks of power definition are discussed in this paper.At last,this p aper point out ,accord to different condition,we can use the right formula tion for the given task. |
