Overview
IEC TR 62689-100:2016 is a Technical Report published by the IEC that defines requirements and proposals for extending the IEC 61850 series data models to fully support fault passage indicators (FPI) applications. The report focuses on current and voltage sensors or detectors used for fault passage indication, covering functional use cases, actor models, information models and proposed logical node (LN) extensions to enable interoperable FPI functionality across distribution automation systems.
Keywords: IEC TR 62689-100, fault passage indicators, IEC 61850, data model extensions, current and voltage sensors
Key topics and technical requirements
- Scope and intent: Prepare requirements and concrete proposals for IEC 61850 data model extensions to support all classes and extended functions of FPIs, providing input for future IEC 61850‑90‑6 and IEC 62689‑3 work.
- Use cases: Comprehensive use cases including generic fault indication, overcurrent and phase-to-earth detection (directional and non-directional), energy-flow monitoring, FLISR (Fault Location, Isolation, and Service Restoration), VVC (Volt/VAR Control) contributions and DER interactions.
- Actors and system models: Identification of common actors and their SGAM positioning to support FPI integration in distribution automation.
- Information models and LNs: Proposed logical node classes and grouping (examples: SFPI Fault Passage Indicator, SCPI Current Presence, SVPI Voltage Presence, SFST Fault Indicator Statistics, and measurement extensions like MMTNExt, MMXNExt). Mapping of requirements to LNs and data objects.
- SCL and enumerations: Definitions for data semantics, DO name conventions, SCL enumerations, and enumerated types (e.g., fault confirmation, permanence, CT arrangements).
- Product lifecycle and configuration: Requirements for IED configuration via CID files and FieldComp use cases for asset management and remote configuration.
Practical applications
- Integrating fault passage indicators into IEC 61850‑based substations and feeder automation.
- Enabling distributed FLISR schemes by sharing standardized FPI status, timestamps and localization data.
- Supporting utilities for faster fault location, service restoration and reduced outage times.
- Allowing manufacturers of sensors, FPIs and IEDs to design interoperable devices conforming to standardized data models.
- Facilitating DER and VVC coordination using standardized energy-flow and presence indications from FPIs.
