标准摘要
[中文适用范围]： IEC 62351 的这一部分定义了特定于电力系统操作的网络和系统管理 (NSM) 数据对象模型。这些 NSM 数据对象将用于监控网络和系统的健康状况、检测可能的安全入侵以及管理信息基础设施的性能和可靠性。目标是定义一组抽象对象，允许远程监控 IED（智能电子设备）、RTU（远程终端单元）、DER（分布式能源）系统和其他重要系统的健康状况和状况。电力系统运行。电力系统运行越来越依赖信息基础设施，包括通信网络、简易爆炸装置和自定义通信协议。因此，信息基础设施的管理对于在电力系统运行中提供必要的高水平安全性和可靠性至关重要。用于传输远程控制和自动化协议的电信基础设施已经受到健康和状态监测控制，使用 IETF 简单网络管理协议 (SNMP) 标准中开发的概念进行网络管理。然而，电力系统特定设备（如远程保护、远程控制、变电站自动化、同步相量、逆变器和保护）需要特定的解决方案来监控其运行状况。 NSM 对象提供用于电力系统的 IEC 协议（IEC 61850、IEC 60870-5-104）以及设备特定环境和安全状态的监控数据。作为 IEC 60870-5-104 的衍生协议，IEEE 1815 DNP3 也包含在受监控协议列表中。 NSM 数据对象使用为 IEC 61850 开发的命名约定，并进行扩展以解决 NSM 问题。为了通用性，这些数据对象以及它们所包含的数据类型被定义为数据对象的抽象模型。除了抽象之外 [外文原描述]： IEC 62351-7:2017 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the remote monitoring of the health and condition of IEDs (Intelligent Electronic Devices), RTUs (Remote Terminal Units), DERs (Distributed Energy Resources) systems and other systems that are important to power system operations. This new edition constitutes a technical revision and includes the following significant technical changes with respect to IEC TS 62351-7 (2010): NSM object data model reviewed and enriched; UML model adopted for NSM objects description; SNMP protocol MIBs translation included as Code Components. The Code Components included in this IEC standard are also available as electronic machine readable file at: https://assets.iec.ch/public/tc57/IEC_62351-7.2017_ed1.0.MIBS.1.0.light.zip?2023053143 .
