+AMD1:2020 CSV 电力公用事业自动化的通信网络和系统 第 8-1 部分：特定通信服务映射 (SCSM) 映射到 MMS（ISO 9506-1 和 ISO 9506-2）和 ISO/IEC 8802-3

[中文适用范围]： IEC 61850-8-1:2011+A1:2020 指定了一种通过将 ACSI 映射到 MMS 和 ISO/IEC 8802-3 帧，通过局域网交换时间关键和非时间关键数据的方法。定义使用 ISO 9506 服务实现数据交换的标准化方法。对于 IEC 61850-7-2 中定义的未映射到 MMS 的 ACSI 服务，本部分定义了附加协议。它使用面向对象的方法描述了真实公用设施设备的外部可见数据和行为。这些对象本质上是抽象的，可用于多种应用。这种映射的使用远远超出了公用事业通信中的应用。相对于前一版本的主要变化如下： - 千兆位以太网的支持， - 链路层冗余， - 对象引用长度的扩展， - 综合日志记录包含类型原因的扩展， - 跟踪服务的映射， - 用于跟踪服务或作为链接时的 objectReference 的第二个映射， - ExtraCause 枚举的扩展， - GOOSE 电报的模拟， - 所谓的固定长度编码GOOSE，- 删除 SCL 控制块。该合并版本由第二版（2011年）及其修正案1（2020年）组成。因此，无需对本出版物进行修订。关键词：低压直流 [外文原描述]： IEC 61850-8-1:2011+A1:2020 specifies a method of exchanging time-critical and non-time-critical data through local-area networks by mapping ACSI to MMS and ISO/IEC 8802-3 frames. Defines a standardized method of using the ISO 9506 services to implement the exchange of data. For those ACSI services defined in IEC 61850-7-2 that are not mapped to MMS, this part defines additional protocols. It describes real utility devices with respect to their external visible data and behaviour using an object oriented approach. The objects are abstract in nature and may be used to a wide variety of applications. The use of this mapping goes far beyond the application in the utility communications. The main changes with respect to the previous edition are listed below: - the support of gigabit Ethernet, - the link layer redundancy, - the extension of the length of the object reference, - the extension of the reason for inclusion type for comprehensive logging, - the mapping of the tracking services, - a second mapping of the objectReference when used in the tracking services, or as linking, - the extension of the AdditionalCause enumeration, - the simulation of GOOSE telegram, - the so-called fixed-length encoded GOOSE, - the removal of the SCL Control Block. 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.
