IEC？62351-7:20 17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，并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）系统和其他对电力系统运行很重要的系统的健康和状况。这个新版本构成了一个技术修订，包括以下关于IEC TS 62351-7(2010)的重大技术变化:NSM对象数据模型的审查和丰富；NSM对象描述采用UML模型；SNMP协议MIBs转换作为代码组件包含。 本IEC标准中包含的代码组件也可作为电子机器使用 可读文件:http://www.iec.ch/tc57/supportdocuments/IEC_62351-7.MIBS.light.zip。

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
