IEC/TR 62051

Overview

IEC/TR 62051 is a technical report developed by the International Electrotechnical Commission (IEC) under Technical Committee 13 (TC 13), focused on electricity metering. This report serves as a comprehensive glossary of terms used in current and emerging standards related to electrical energy measurement and management. It provides clear and standardized definitions that support consistency across international practices and regulations in the metering domain.

This publication is particularly important for stakeholders involved in Smart Grid technologies, offering essential terminology related to electrical energy measurement, tariff and load control, and customer-utility information exchange systems. It also addresses terminology for Distribution Automation Systems beyond the scope of IEC 60050(371), and terms pertinent to electricity prepayment systems and metering equipment dependability.

Key Topics

IEC/TR 62051 covers a broad range of crucial concepts within electricity metering, including but not limited to:

• Electrical Energy Measurement
  Definitions related to how electrical energy consumption is quantified and recorded.

• Tariff and Load Control
  Terminology describing pricing models, consumption-based tariffs, and mechanisms controlling electrical load to optimize grid efficiency.

• Customer-Utility Information Exchange
  Terms that cover communication protocols and data exchange between consumers and electricity providers to enable better service and billing accuracy.

• Distribution Automation Systems
  Glossary entries advancing beyond traditional standards, focusing on automation and control technologies in electrical distribution networks.

• Electricity Prepayment Systems
  Definitions related to systems allowing customers to pay for electricity in advance, enhancing credit management and consumption control.

• Dependability of Metering Equipment
  Terms defining the reliability, accuracy, and operational safety of metering devices.

Applications

The standard terminology outlined in IEC/TR 62051 is vital for:

• Utility Companies
  Streamlining communication and documentation regarding metering systems and customer services.

• Smart Grid Development
  Facilitating interoperability and clarity in system components by providing unified definitions for key Smart Grid concepts.

• Manufacturers and Suppliers
  Ensuring consistency in product specifications, documentation, and compliance with international terminology standards.

• Regulators and Policy Makers
  Supporting the creation of coherent regulations and policies by applying standardized language, thus improving industry-wide understanding.

• Researchers and Educators
  Offering a foundational vocabulary for the study and teaching of electricity metering and related technologies.

Related Standards

IEC/TR 62051 complements other IEC and international standards in the electrical energy domain, such as:

• IEC 60050(371) – International Electrotechnical Vocabulary for Distribution Automation Systems
• IEC 62053 series – Electricity metering equipment (accuracy classes and performance criteria)
• IEC 62054 series – Electricity meters – Particular requirements, tests, and test conditions
• IEC 62325 – Standard profiles for data exchange in deregulated energy market environments

By cross-referencing these standards, IEC/TR 62051 helps build a robust framework essential for aligning terminology across various facets of electricity metering and Smart Grid infrastructure.
