IEC TR 61850-90-2:2016

IEC TR 61850-90-2:2016 addresses communication networks and systems for power utility automation, with a specific focus on using IEC 61850 for communication between substations and control centres. For organizations working on utility automation projects, it can serve as a practical technical reference during engineering review, procurement checks, and documented evaluation of communication architectures. The document is relevant where interoperability, operational consistency, and compliance workflows depend on a clear understanding of how substation and control-centre communications are intended to be structured.

Overview of IEC TR 61850-90-2:2016

IEC TR 61850-90-2:2016 provides guidance connected to the wider IEC 61850 framework, with emphasis on communication paths between substations and control centres in power utility environments. As a technical reference, it is useful for teams assessing system integration, network design assumptions, and related engineering documentation. The edition and publication context help identify the specific version to use during technical assessment, verification activities, and conformity assessment preparation, particularly when aligning utility communications with established architecture and documentation practices.

Compliance applications of IEC TR 61850-90-2:2016

In compliance workflows, IEC TR 61850-90-2:2016 may be used to support review of substation automation projects, control-centre interface planning, and system documentation for utility communication networks. It is especially relevant to engineering teams, test laboratories, and procurement specialists who need a reliable reference during product evaluation, technical validation, or supplier comparison. The document can also assist with regulatory preparation and quality workflows where communication behavior, integration assumptions, and network-related requirements need to be traced and reviewed in a controlled manner.

Importance of compliance with IEC TR 61850-90-2:2016

Using IEC TR 61850-90-2:2016 as part of a technical compliance process helps reduce integration risk and improve consistency between substations and control centres. For power utility automation projects, that can support safer system operation, clearer interoperability expectations, and more disciplined testing workflows. It also helps organizations structure documentation for procurement, engineering validation, and conformity assessment preparation. When communication design is reviewed against a recognized technical reference, teams are better positioned to identify implementation gaps early and maintain operational consistency across the wider automation environment.
