SIST EN IEC 60633:2020/AC:2020

Overview

SIST EN IEC 60633:2020/AC:2020 is a European and international standard focusing on the vocabulary associated with High-Voltage Direct Current (HVDC) transmission systems. Adopting the amendments of IEC 60633:2019/COR1:2020, it serves as a comprehensive reference for defining terms used in HVDC technology. Developed by the Slovenian Institute for Standardization (SIST) and aligned with CENELEC processes, this standard plays an essential role in ensuring clear communication, consistency, and safety across HVDC transmission projects.

HVDC systems are integral for efficient long-distance electric power transmission. The vocabulary outlined in this standard supports engineers, manufacturers, and regulatory bodies by promoting a unified language and reducing ambiguity in documentation and design.

Key Topics

The standard establishes clear terminology relevant to HVDC transmission, covering:

• Definitions of essential concepts in HVDC technology, applicable to design, construction, and operation.
• Hierarchical control systems in HVDC networks, including converter bridges, thyristor levels, and master/pole controls.
• Component descriptions for key elements such as valve electronics, converter units, and control systems.
• System and process terms that support maintenance, interoperability, and standardization within the electrical engineering sector.

The inclusion of a corrigendum ensures that the vocabulary remains accurate and reflects the latest industry understanding.

Applications

Standardized HVDC vocabulary is critical for a broad range of practical scenarios, such as:

• Design and Specification Documentation: Ensuring all parties involved in HVDC projects use consistent and harmonized terminology for technical drawings, contracts, and manuals.
• Interoperability Between Manufacturers: Facilitating the integration of system components from different vendors through shared definitions.
• Regulatory Compliance: Meeting regional and international requirements for documentation in procurement, maintenance, and safety assessments.
• Training and Knowledge Transfer: Providing a foundation for educational materials and professional development in the energy sector.
• Project Management: Streamlining communication within multidisciplinary teams working on HVDC transmission infrastructure.

By adopting the terminology in SIST EN IEC 60633:2020/AC:2020, organizations contribute to safer, more reliable, and more efficient HVDC power transmission projects.
