IEC 61803:2020

IEC 61803:2020 is the technical reference for determining power losses in high-voltage direct current (HVDC) converter stations with line-commutated converters. It is relevant where engineering teams, utilities, and test specialists need a consistent basis for evaluating converter station efficiency and comparing loss figures during technical review, procurement, and conformity assessment. As an original edition, it serves as the primary document for documenting how loss determination should be approached in HVDC projects, supporting clearer engineering documentation and more reliable compliance workflows.

Purpose of IEC 61803:2020

The purpose of IEC 61803:2020 is to provide a structured method for assessing power losses in HVDC converter stations using line-commutated converters. That makes it useful for technical validation, performance analysis, and documented evaluation of station behavior under defined conditions. In practice, it helps stakeholders align calculations, measurements, and reporting expectations when reviewing converter station efficiency, supporting risk management and operational consistency across engineering and quality workflows.

Compliance applications of IEC 61803:2020

This reference is commonly used in HVDC project specifications, factory or site verification activities, and engineering documentation where loss determination must be addressed in a defensible way. It may support procurement review, acceptance testing, and regulatory preparation for converter station equipment and associated systems. For organizations handling technical assessment or laboratory evaluation, it provides a focused basis for comparing results and maintaining consistency in testing workflows tied to line-commutated converter installations.

Benefits of IEC 61803:2020

Using IEC 61803:2020 can improve clarity in conformity assessment and reduce ambiguity when power loss figures are reviewed by multiple stakeholders. A common technical reference supports better interoperability between design, test, and procurement teams, especially when performance data must be checked against project requirements. It also helps strengthen safety-related decision-making, quality assurance, and engineering validation by promoting a repeatable basis for documenting losses in HVDC converter stations.
