Full title and description

STB PD CLC TR 50609-2014 — Technical Guidelines for Radial HVDC Networks. This Published Document (PD) from the CLC/CENELEC family provides guidance on the planning, topology, equipment selection, operation, protection and testing of radial high-voltage direct current (HVDC) transmission networks (sometimes referred to as spoke or radial HVDC systems), with emphasis on networks that connect multiple converter stations to a common DC transmission arrangement.

Abstract

This technical guideline describes recommended practices and considerations for the design and operation of radial HVDC networks. It covers network topology options, converter-station interfaces, control and protection principles, operational planning, testing and commissioning measures, and interfaces with AC systems. The document is intended to help system planners, OEMs and transmission operators apply consistent approaches to radial HVDC schemes.

Scope

The document gives technical guidance for radial (spoke-type) HVDC systems where multiple converter stations are connected into a DC network or to a common DC arrangement. It addresses functional and technical aspects relevant to system planners and operators rather than providing prescriptive, normative test methods — i.e., it is a guideline/technical report intended to inform design choices, control and protection strategies, system studies and commissioning of radial HVDC arrangements.

Key topics and requirements

• Overview of radial HVDC topologies and when radial solutions are appropriate.
• Converter-station interfaces and requirements for multi-terminal connections.
• Control and coordination principles for voltage-sourced and line-commutated converters in radial arrangements.
• Protection philosophy, fault handling and islanding considerations for DC networks.
• Recommendations for testing, commissioning and system acceptance procedures.
• Operational planning, steady-state and dynamic studies, and interaction with AC systems.

Typical use and users

Intended users include transmission system planners, HVDC equipment manufacturers (OEMs), grid operators, consulting engineers and testing/commissioning teams. Typical uses are project design reviews, specification writing for converter stations and protection systems, system studies for multi-terminal HVDC projects, and as a reference during commissioning and operational procedure development.

Related standards

This PD is typically used together with other HVDC and high-voltage standards and technical reports, for example IEC TR 62543 (VSC HVDC), IEC 61975 (system tests for HVDC installations), IEC 60700 series (thyristor valve testing) and high-voltage testing standards referenced for commissioning and partial-discharge testing. Users should consult the applicable IEC and national standards for prescriptive test methods and normative requirements.

FAQ

Q: What is this standard?

A: It is PD CLC/TR 50609:2014 — a CENELEC Published Document (technical guideline) titled "Technical Guidelines for Radial HVDC Networks" providing guidance for planning and operating radial HVDC systems.

Q: What does it cover?

A: The guideline covers topology choices for radial HVDC, converter-station interfaces, control and protection principles, operational planning, testing and commissioning recommendations, and interactions with AC networks. It is advisory rather than a prescriptive test standard.

Q: Who typically uses it?

A: Transmission planners, HVDC equipment manufacturers, grid operators, consulting engineers, and commissioning/test teams use it as a practical reference during design, specification and commissioning of radial HVDC projects.

Q: Is it current or superseded?

A: Catalogue entries and national distributors list PD CLC/TR 50609:2014 as an active Published Document. Users should check with their national standards body or the CENELEC/BSI catalogue for any later amendments or successor documents before relying on it for regulatory compliance.

Q: Is it part of a series?

A: It is a CLC Published Document (PD) and sits alongside other HVDC-related IEC and CENELEC technical reports and standards; it is commonly referenced together with relevant IEC HVDC standards and technical reports for detailed normative requirements.
