摘　　要：在电力市场化的条件下如何计算谐波电能和暂态电能,谐波电能和暂态电能损耗由谁承担,以及这部分损耗采取何种计费标准,都是亟待解决的问题。本文首先分析了瞬时功率的构成,得到有功功率的公式,接着探讨了前置滤波器对电能计量的影响、暂态情况下的电能计量问题和用户类型对电能转换的影响,最后对有功计费提出了一些建议。On the power market, how to calculate harmonic and transient energy loss and their prices, and who should pay for them are all the problems which are urgently needed to resolve. First, this paper lists formula of active power by analyzing the composing of instantaneous power, then discusses the effect of prefilter to electric energy metering, how to measure electric energy in transient condition, and the influence of load type to the conversion of electric energy. And finally some advices are put forward.

关 键 词：谐波暂态 电能 有功 滤波器
