Overview
IEC TR 63127:2019/AMD1:2024 is an important amendment to the original IEC Technical Report 63127:2019. This amendment provides updated guidelines for the system design of HVDC (High Voltage Direct Current) converter stations using line-commutated converters (LCC). Issued by the International Electrotechnical Commission (IEC), this report targets professionals and engineers involved in HVDC systems and contributes to standardizing design practices worldwide.
The updated document reflects advancements in HVDC technology, addressing the increasing integration of renewable energy sources and evolving grid conditions. With a focus on optimizing HVDC converter station design, the amendment enhances system reliability, stability, and efficiency for DC voltage levels above 100 kV.
Key Topics
HVDC Converter Station Design: The standard provides detailed system design guidelines for HVDC converter stations employing line-commutated converters. It helps optimize configurations to accommodate evolving power system requirements.
AC/DC Interaction and Control: It updates approaches on managing interactions between HVDC converter stations and the AC system, including control strategies necessary for stable operation.
Short-Circuit Current and System Strength: The amendment places emphasis on the effect of AC system strength on HVDC system design. It highlights how weak AC networks require specialized control techniques, reactive power compensation devices (STATCOM, SVC, TCSC), and explains the role of short-circuit ratio (SCR) and effective short-circuit ratio (ESCR) in planning.
Reactive Power Consumption Calculations: The standard revises important equations used in calculating reactive power consumption in converter valves, facilitating more accurate design and performance prediction.
Converter Station Components: Modifications include terminology updates (e.g., neutral bus earthing switch) and design recommendations for components such as converter valves and transformer enclosures.
Power Level and Voltage Ratings: Recommendations now consider power ratings up to 12,000 MW at ±1,100 kV, reflecting progress in high-voltage DC transmission capabilities.
Applications
IEC TR 63127:2019/AMD1:2024 is essential for:
HVDC Project Planning and Design: Engineers involved in the planning, design, and operation of HVDC converter stations will apply these guidelines to ensure safe, reliable, and efficient integration of HVDC links into AC grids.
Renewable Energy Integration: With increasing connections of renewable energy sources affecting system strength, the guidelines support adaptations in HVDC station design to maintain stability and power quality.
Grid Reinforcement and Expansion: Utilities undertaking grid reinforcement using HVDC technology will benefit from the updated recommendations on system strength evaluation, reactive power compensation, and control strategies.
Standardization and Regulatory Compliance: The document assists manufacturers, operators, and regulatory bodies in aligning HVDC systems to recognized international standards, facilitating interoperability and harmonization.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s).
IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect
thereof
