本文首先介绍一种分析方法能够导出应用于在频域中计算能量的公式。此公式可以认为是 Parseval 定理的一种伸化,它对于计算脉冲的能量值十分有用,而这种能量在时域中是很难处理的。根据该公式的算法已经编制成公式翻译(Fortran)程序。这种算法程序的详细情况在其它文献中已有论述,本文只准备作较为简略的介绍。最后,我们还将讨论这种方法在计算配电网络中瞬变能量的应用情况。
This article first introduces an analysis method that derives formulas that apply to the calculation of energy in the frequency domain. This formula can be considered a kind of extension of Parseval’s theorem, it is very useful for calculating the energy value of the pulse, and this kind of energy is very difficult to deal with in the time domain. The algorithm according to this formula has been compiled as a formula translation (Fortran) program. The details of this algorithmic program have been discussed in other documents and this article is intended to be a brief introduction. Finally, we will also discuss the application of this method in the calculation of transient energy in distribution networks.
