IEC 61850-7-3:20 0+A1:2020适用于变电站和馈线设备的设备型号和功能的描述。它指定了与变电站应用相关的构造属性类和公共数据类。特别地，它指定用于状态信息的公共数据类、用于测量信息的公共数据类、用于控制的公共数据类、用于状态设置的公共数据类、用于模拟设置的公共数据类以及在这些公共数据类中使用的属性类型。第二版定义了新的通用数据类，用于定义基于IEC 61850的其他领域的对象模型的新标准，以及统计和历史数据的表示。 该出版物与智能电网具有核心相关性。该合并版本由第二版（2010年）及其修正案1（2020年）组成。因此，除本出版物外，无需下令修订。

IEC 61850-7-3:2010+A1:2020 is applicable to the description of device models and functions of substations and feeder equipment. It specifies constructed attribute classes and common data classes related to substation applications. In particular, it specifies common data classes for status information, common data classes for measured information, common data classes for control, common data classes for status settings, common data classes for analogue settings and attribute types used in these common data classes. This second edition defines new common data classes used for new standards defining object models for other domains based on IEC 61850 and for the representation of statistical and historical data.
This publication is of core relevance for Smart Grid. This consolidated version consists of the second edition (2010) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
