Overview
EN 62751-1:2014/A2:2022 is a European standard developed by CENELEC that addresses power losses in voltage sourced converter (VSC) valves used in high-voltage direct current (HVDC) systems. This amendment (A2) updates Part 1 of the original 2014 standard by incorporating the latest technical and methodological advances to standardize the calculation and assessment of power losses in VSC valves effectively. It aims to enable accurate, repeatable, and comparable loss evaluations, critical for the design, procurement, and operation of efficient HVDC transmission systems.
The standard aligns with the international IEC 62751-1:2014/AMD2:2022 document and was approved by CENELEC in April 2022. It serves as a reference to optimize HVDC converter valve performance by defining general requirements and methodologies for loss determination, essential for power electronics in electrical transmission and distribution.
Key Topics
Power Loss Calculation Method:
The standard specifies a consistent method to calculate total losses in HVDC converter stations by aggregating losses from individual components, enhancing the buyer’s ability to compare offers from different manufacturers.Standard Reference Conditions:
It outlines default environmental and operational conditions-such as ambient temperature, atmospheric pressure, humidity, power transmission levels-to ensure uniformity in loss measurement when purchasers do not provide custom specifications.Component Loss Characterization:
Includes definitions and revised terminology related to IGBT (Insulated Gate Bipolar Transistor) switching energies (turn-on, turn-off) and diode reverse recovery energy to standardize the approach across different converter valve technologies.Sampling and Measurement Guidelines:
Guidance on selecting the appropriate sampling period for losses measurements, taking into consideration converter modulation strategies such as pulse width modulation (PWM), ensuring realistic and relevant loss data.Redundancy Treatment and Operational Scenarios:
Introduces considerations for worst-case scenarios-including network, ambient, and power conditions-especially for equipment rating and contractual guarantees, ensuring robust design and operation.Updated References:
Integrates updated normative references, notably substituting IEC 61803:2020 for earlier versions, to reflect the most current international guidelines on power loss determination in HVDC converter stations.Experimental Validation Insights:
Discusses practical measurement challenges, including thermal and electrical loss measurements during type testing and on-site assessments, highlighting the need for improved methods and reliance on experimentally derived data.
Applications
HVDC Converter Station Design:
Enables engineering teams to accurately estimate valve losses, leading to optimized cooling systems, component selection, and overall station efficiency.Vendor Bid Evaluation:
Standardized loss calculation methods facilitate fair and transparent comparison of HVDC system proposals, assisting purchasers in choosing solutions that meet both performance and contractual requirements.Performance Curve Generation:
Supports development of loss curves under varying operational conditions, improving operational planning, real-time monitoring, and predictive maintenance strategies.Quality Assurance in Manufacturing:
Provides manufacturers with unified metrics for valve power loss characterization essential for conformity with industry benchmarks and compliance testing.Academic and R&D Use:
Serves as a foundation for research into loss reduction techniques and innovative converter technologies that target improved HVDC system efficiency.

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) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
