IEC 61850-7-1:20 1+A1:2020介绍了IEC 61850-7系列各个部分中使用的建模方法、通信原理和信息模型。目的是从概念的角度提供帮助，以理解以下方面的基本建模概念和描述方法: -用于电力设施自动化系统的变电站特定信息模型， -用于电力设施自动化目的的设备功能，以及 -在电力设施内提供互操作性的通信系统。与第一版相比，第二版介绍了: -统计和历史统计数据的模型， -代理、网关、LD层级和LN输入的概念， -用于时间同步的模型， -不同测试设施背后的概念， -扩展的日志记录功能。它还澄清了某些项目。 该合并版本由第二版（2011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 61850-7-1:2011+A1:2020 introduces the modelling methods, communication principles, and information models that are used in the various parts of the IEC 61850-7 series. The purpose is to provide - from a conceptual point of view - assistance to understand the basic modelling concepts and description methods for:
- substation-specific information models for power utility automation systems,
- device functions used for power utility automation purposes, and
- communication systems to provide interoperability within power utility facilities. Compared to the first edition, this second edition introduces:
- the model for statistical and historical statistical data,
- the concepts of proxies, gateways, LD hierarchy and LN inputs,
- the model for time synchronisation,
- the concepts behind different testing facilities,
- the extended logging function. It also clarifies certain items.
This consolidated version consists of the second edition (2011) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
