IEEE 1379-2000

IEEE 1379-2000 is a technical standard for data communications between remote terminal units and intelligent electronic devices in a substation. It addresses how these devices exchange information in power-system environments, where reliable communication is important for monitoring, control, and coordinated operation. For engineering teams working in power, energy, and industrial applications, the document helps define a common basis for communication behavior and system integration across substation equipment.

IEEE 1379-2000 overview

This standard focuses on communication practices for substation automation, specifically the interaction between remote terminal units and intelligent electronic devices. IEEE 1379-2000 is relevant where data must move consistently between field equipment and supervisory or control functions. By outlining a recommended practice rather than a purely product-specific approach, it supports more predictable integration of devices used in electrical substations and related infrastructure. That makes it useful when evaluating system design, interoperability, and communication requirements.

Typical use cases

IEEE 1379-2000 is commonly associated with substation data links that connect RTUs to protection, monitoring, or control devices. It may be used when defining communication paths for status reporting, measurements, alarms, or operational commands within utility substations and similar power installations. The standard is also relevant during system design or retrofit work where mixed equipment from different vendors must exchange data in a controlled and dependable way.

Why this standard matters

In substation applications, communication problems can affect visibility, control, and operational reliability. IEEE 1379-2000 matters because it helps establish a shared technical basis for how RTUs and intelligent electronic devices communicate, which can reduce integration risk and support consistent engineering decisions. It may also assist with procurement and testing by giving project teams a recognized reference for expected communication practices, especially when coordinating equipment across power, energy, and industry applications.
