Overview
IEC 60050-601:1985/AMD1:1998 is an important amendment to the International Electrotechnical Vocabulary (IEV), specifically Part 601, which addresses the generation, transmission, and distribution of electricity - general terminology. This amendment was developed by IEC Working Group 191-3, focused on reliability and quality of service in electric power systems. It enhances the IEV by adding comprehensive definitions and clarifications related to the electrical power generation and transmission infrastructure.
This standard primarily applies to direct acting indicating analogue phase meters, power factor meters, synchroscopes, and their associated non-interchangeable accessories. It is essential for professionals working with electric power systems, helping unify terminology and improve communication across engineering disciplines and international borders.
Key Topics
Fundamental Terms in Power Systems
- Bulk Power System (BPS) / Bulk Electricity System (BES): Refers to the portion of the electric power grid that includes production and transmission facilities serving large industrial consumers and distribution centers.
- Also known as the "composite system", the BPS is crucial for understanding the large-scale infrastructure supporting electricity flow.
System Configuration Terms
- Circuit (in electric power systems): A segment of an electrical line or network that can be independently isolated by switches or breakers without affecting other segments.
- Line Tap or Tee Point: A junction on a multi-terminal line where three or more line sections meet. It plays a key role in network flexibility and maintenance.
- Line Section: A portion of an electric line bounded by two points (line ends or taps).
- Line Segment: A part of a line section characterized by specific construction or failure exposure, used for detailed reliability and failure analysis.
- Interchange Point: The interface point where electric energy is exchanged between producers, distributors, or consumers.
- Delivery Point: The interface between the electric power system and the end user or a distribution entity supplying final users.
Applications
The amendment provides standardized terminology vital for several practical scenarios:
- Design and Operation of Power Systems: Accurate identification and classification of network components improve system design, operation, and fault handling.
- Reliability Analysis: Terms like line segment enable precise reporting and analysis of failures, increasing network reliability.
- Energy Trading and Exchange: Clear definitions of interchange and delivery points facilitate contractual and operational frameworks for power exchange between utilities and consumers.
- Metering and Monitoring Equipment: The scope covers analogue phase meters and synchroscopes, ensuring consistent terminology in device specifications, installation, and maintenance procedures.
Utility companies, system operators, equipment manufacturers, engineers, and regulatory bodies benefit from the clear, harmonized vocabulary fostered by this amendment.
Related Standards
IEC 60050 series serves as the fundamental reference for electrotechnical terminology, interconnected with other standards in power generation and distribution such as:
- IEC 60050-601 original publication providing base vocabulary.
- Other parts of IEC 60050 covering specific electrical domains like power transformers, switchgear, and power quality.
- IEC standards on measurement instruments and metering technologies.
- International standards for grid operation, reliability criteria, and energy transaction protocols referencing standardized terms from IEC 60050.
For more in-depth technical guidelines, these related IEC publications ensure consistent terminology and interoperability across the electric power sector.
Keywords: IEC 60050-601, International Electrotechnical Vocabulary, power generation terminology, bulk power system, electric power circuit, line section, interchange point, delivery point, analogue phase meter, power factor meter, synchroscope, electric power transmission, electricity distribution standards, IEC terminology amendment.
