What is BS EN 62351‑7 - Power systems management and associated information exchange about?
BS EN 62351 is a series on power systems management and associated information exchange. Power systems management and associated information exchange allow our customers to select important power supply parameters over a digital communication interface. BS EN 62351‑7 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, detect possible security intrusions, and 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.
In addition to the abstract model, in order to allow the integration of the monitoring of power system devices within the NSM environment in BS EN 62351‑7, a mapping of objects to the SNMP protocol of Management Information Base (MIBs) is provided.

Why should you use BS EN 62351‑7 - Power systems management and associated information exchange?
Power systems operations are increasingly reliant on information infrastructures, including communication networks, IEDs, and self-defining communication protocols. Therefore, management of the information infrastructure has become crucial to providing the necessary high levels of security and reliability in power system operations. The telecommunication infrastructure that is in use for the transport of telecontrol and automation protocols is already subject to health and condition monitoring control, using the concepts developed in the IETF Simple Network Management Protocol (SNMP) standards for network management. However, power system specific devices (like tele-protection, telecontrol, substation automation, synchro-phasors, inverters, and protections) need instead a specific solution for monitoring their health.
The NSM objects as defined in BS EN 62351‑7 provide monitoring data for IEC protocols used for power systems (IEC 61850, IEC 60870-5-104) and device-specific environmental and security status. As a derivative of IEC 60870-5-104, IEEE 1815 DNP3 is also included in the list of monitored protocols. The NSM data objects use the naming conventions developed for IEC 61850, expanded to address NSM issues. For the sake of generality these data objects, and the data types of which they are comprised, are defined as abstract models of data objects. The information infrastructure in power operations consists not only of the communication networks, but also of the data that is exchanged between systems, stored in databases, and used by applications in power system operations. This information infrastructure is not typically treated as a coherent infrastructure but is viewed as a disparate collection of communication channels, groups of distinct network segments, separate devices, various databases, and different protocols. Often SCADA (Supervisory Control and Data Acquisition) systems perform some communications monitoring, such as whether connections are available to their remote terminal units (RTUs), and they flag the event as connection lost when connections fail. However, the real-time coherent, complete, and homogeneous health status of the overall information infrastructure has been missing. Such real-time information infrastructure health status can support operators to detect and mitigate potential problems in the power system. Using BS EN 62351‑7 you can define network and system management (NSM) data object models that are specific to power system operations.
