Full title and description

STB DIN IEC 61850-7-4_A1_Sept2006_ENTWURF — Draft (Entwurf) of the DIN adoption of IEC 61850-7-4 Amendment 1, published September 1, 2006. The document contains amendment material to IEC 61850‑7‑4 introducing additions for power quality monitoring and related compatible logical node and data object classes for substation and feeder equipment.

Abstract

This draft amendment (A1) to IEC 61850‑7‑4 defines new and extended logical node classes and data object classes to support power quality monitoring and related measurements within the IEC 61850 information model. It clarifies data modelling for power-quality related quantities, provides definitions and naming conventions consistent with the IEC 61850 family, and supplies the amendment text proposed for national adoption as a DIN document (Entwurf).

General information

• Status: Draft (Entwurf) published as DIN draft amendment; later withdrawn and integrated into subsequent EN/DIN editions (see note below).
• Publication date: 01 September 2006.
• Publisher: Deutsches Institut für Normung (DIN) — national adoption of IEC amendment text.
• ICS / categories: 33.040.40 (Data communication networks — Ethernet); related to 13.020 (Electrical engineering) / 13.020.45 as used in national catalogues.
• Edition / version: Amendment A1 to IEC 61850‑7‑4 (A1, Sept 2006 draft for DIN adoption).
• Number of pages: Approximately 36 pages (draft amendment document length).

Scope

The amendment provides additions to the IEC 61850‑7‑4 information model specifically to represent power quality monitoring functions and their data. It defines compatible logical node classes and data object classes required to exchange power-quality related measurements (e.g., voltage quality parameters, harmonics, flicker, RMS values and associated statistical/monitoring data) between intelligent electronic devices (IEDs) and supervisory/control systems within substations and feeder-level equipment.

Key topics and requirements

• Definition and naming of logical nodes and data objects for power quality monitoring.
• Extensions to the IEC 61850 information model to support power-quality metrics (harmonics, flicker, RMS, event/statistical data).
• Guidance for mapping measurement quantities to existing IEC 61850 data classes and for ensuring compatibility with earlier parts of the series.
• Clarifications and corrections related to representation of historical and statistical power-quality information.
• National adoption notes as a DIN draft (Entwurf) for inclusion in EN/DIN editions.

Typical use and users

Intended users include power utility engineers, substation automation designers, IED and protection/control device manufacturers, system integrators, testing and certification laboratories, and consultants working on IEC 61850-compliant power-quality monitoring and substation automation projects. The amendment is used when modelling or implementing power-quality measurement and reporting functions in IEC 61850 device models.

Related standards

Part of the IEC 61850 standard series (Communication networks and systems for power utility automation). Closely related items include IEC 61850‑7‑3 (common data classes), IEC 61850‑7‑2 (abstract communication service interface), IEC 61850‑8‑1 (mapping to MMS/GOOSE), IEC 61850‑6 (SCL), and the consolidated EN/DIN editions such as DIN EN 61850‑7‑4:2010 and later revisions (which incorporate amendment material). The national draft was subsequently superseded by later EN/DIN publications consolidating amendments into the 2010 and later releases of EN 61850‑7‑4 and its A1 editions (see national catalogue entries and DIN listings).

FAQ

Q: What is this standard?

A: It is the DIN draft (Entwurf) of Amendment 1 to IEC 61850‑7‑4 (A1), published as a national draft in September 2006 to add power-quality related logical nodes and data object classes to the IEC 61850 information model.

Q: What does it cover?

A: It covers additions and clarifications to the IEC 61850‑7‑4 information model to represent power quality measurements, including naming and structure of logical nodes and data objects, representation of statistical and historical power-quality data, and mapping guidance to existing IEC 61850 constructs.

Q: Who typically uses it?

A: Utility engineers, IED and protection device manufacturers, system integrators, testing labs and consultants who implement or model power-quality monitoring and reporting using the IEC 61850 framework.

Q: Is it current or superseded?

A: The 2006 DIN draft amendment was later withdrawn as a standalone national draft and its material was incorporated into subsequent EN/DIN publications (notably the EN/DIN 61850‑7‑4 edition of 2010 and later amendments/revisions). For current normative requirements consult the consolidated EN/DIN IEC 61850‑7‑4 editions (including later A1 releases and the 2022 consolidated DIN EN 61850‑7‑4 edition).

Q: Is it part of a series?

A: Yes — it is an amendment to part 7‑4 of the IEC 61850 series (Communication networks and systems for power utility automation), and should be read in the context of the whole IEC 61850 family (parts 1–10 and related amendments).

Q: What are the key keywords?

A: Power quality, logical nodes, data objects, IEC 61850, substation automation, amendment A1, DIN Entwurf, measurement modelling.
