标准摘要
[中文适用范围]： 本标准涵盖了电力公用自动化通信网络和系统的广域网（WAN）工程设计指南。它概述了用于电力公用事业的广域网的拓扑、技术、协议、安全以及在不同应用场景（如遥测保护、广域监控系统、故障定位、配电自动化等）下的通信要求。 [外文原描述]： IEC TR 61850-90-12:2020, which is a Technical Report, is intended for an audience familiar with electrical power automation based on IEC 61850 and related power system management, and particularly for data network engineers and system integrators. It is intended to help them to understand the technologies, configure a wide area network, define requirements, write specifications, select components, and conduct tests. This document provides definitions, guidelines, and recommendations for the engineering of WANs, in particular for protection, control and monitoring based on IEC 61850 and related standards. This document addresses substation-to-substation communication, substation-to-control centre, and control centre-to-control centre communication. In particular, this document addresses the most critical aspects of IEC 61850 such as protection related data transmission via GOOSE and SMVs, and the multicast transfer of large volumes of synchrophasor data. The document addresses issues such as topology, redundancy, traffic latency and quality of service, traffic management, clock synchronization, security, and maintenance of the network. This document contains use cases that show how utilities tackle their WAN engineering. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) extension of use case with respect to distribution and customer-side applications; b) extensions of wireless access technologies as well as power line communication ones applicable to the above-mentioned use case; c) revisions regarding radio communication technology performance; d) extension of network migration with respect to packet switched network; e) a new mapping of multiprotocol label switching technology to teleprotection.
