IEC TR 61000-4-40:2020是一份技术报告，涉及电力量（均方根电压、均方根电流和有功功率）的评估。本文解释并比较了两种适用于波动或非周期性负荷下电量测量的数字算法。这些例子来自50赫兹或60赫兹的电力系统。本文件并不试图涵盖用于波动负载电量评估的算法的所有可能的数字实现，例如在几个IEC文件中描述的EMC评估的背景下。相反，它将平均值与一种滤波算法进行比较。本文档旨在强调一些应用程序示例，以说明所提出的算法是如何工作的。此外，还为量化每种方法的准确性提供了指导。

IEC TR 61000-4-40:2020 which is a Technical Report, deals with the assessment of electrical power quantities (RMS voltage, RMS current and active power). It explains and compares two digital algorithms suitable for power quantity measurements in fluctuating or non-periodic loads. The examples are from 50 Hz or 60 Hz power systems. This document does not attempt to cover all possible digital implementations of the algorithms used for power quantity assessment in fluctuating loads, for example in the context of the EMC assessment described in several IEC documents. Rather, it compares averaging with one of the filtering algorithms. This document aims to highlight some examples of applications that illustrate how the presented algorithms work. Further, guidance is given for quantifying the accuracy of each approach.
