电力设施自动化用通信网络和系统.第5部分:功能和设备型号的通信要求

[中文适用范围]： 本标准定义了用于电力公用事业自动化的通信网络和系统的基本通信结构，特别是针对分布式能源（DER）和配电自动化的逻辑节点。它规定了数据模型命名空间、版本、代码组件分布以及从IEC 61850-7-420:2009（第1版）到第2.0版的变更。本标准还涵盖了分布式能源设施及电厂的层级概念、通用模型及其组件、电源管理模型、电气连接点（ECP）模型、运行功能模型以及与分布式能源资源相关的各种逻辑节点（如发电机、储能、负载等）的详细定义。 [外文原描述]： IEC 61850-7-420:2021 defines the IEC 61850 information models to be used in the exchange of information with distributed energy resources (DER) and Distribution Automation (DA) systems. DERs include distribution-connected generation systems, energy storage systems, and controllable loads, as well as facility DER management systems, including aggregated DER, such as plant control systems, facility DER energy management systems (EMS), building EMS, campus EMS, community EMS, microgrid EMS, etc. DA equipment includes equipment used to manage distribution circuits, including automated switches, fault indicators, capacitor banks, voltage regulators, and other power management devices. The IEC 61850 DER information model standard utilizes existing IEC 61850-7-4 logical nodes where possible, while defining DER and DA specific logical nodes to provide the necessary data objects for DER and DA functions, including for the DER interconnection grid codes specified by various countries and regions. Although this document explicitly addresses distribution-connected resources, most of the resource capabilities, operational functions, and architectures are also applicable to transmission-connected resources. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Generic approach of modelling to support any kinds of DER including generation, storage and controllable loads; b) Generic approach to support physical and virtual aggregation of DERs; c) Full support of a wide range of operational functions to cover in particular grid codes functions as expressed in IEEE 1547 and EN 50549 or IEC 62786.
