标准摘要
[中文适用范围]: 本部分IEC 61850系列介绍了IEC 61850-7-x系列各部分中使用的建模方法、通信原理和信息模型。本部分的目的是从概念角度提供帮助,以理解以下内容的基本建模概念和描述方法: - 电力公用事业自动化系统的变电站特定信息模型, - 用于电力公用事业自动化目的的装置功能,以及 - 通信系统以提供电力公用事业设施内的互操作性。 此外,本部分还提供了关于IEC 61850-7-4、IEC 61850-7-3、IEC 61850-7-2和IEC 61850-5之间关系的详细要求和解释。本部分解释了IEC 61850-7-x系列的抽象服务及模型如何映射到IEC 61850-8-1中定义的具体通信协议。 本部分提供的概念和模型也可用于描述以下信息模型和功能: - 水力发电厂, - 变电站之间的信息交换, - 分布式自动化的信息交换, - 变电站与控制中心的信息交换, - 计量的信息交换, - 状态监测和诊断,以及 - 与工程系统进行装置配置的信息交换。 [外文原描述]: IEC 61850-7-1:2011 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.
