About This Item
IEC 62751-2:2014/AMD2:2023 is a targeted amendment linked to the parent document for power losses in voltage sourced converter (VSC) valves for high-voltage direct current (HVDC) systems, specifically for modular multilevel converters. It matters for engineering teams, test laboratories, and compliance reviewers because it helps keep technical references aligned with current requirements when evaluating converter-valve loss-related performance. IEC 62751-2:2014/AMD2:2023 should be used as a supporting modification to the base document during technical review, procurement checks, and conformity assessment preparation.
Purpose of IEC 62751-2:2014/AMD2:2023
The purpose of IEC 62751-2:2014/AMD2:2023 is to update the parent reference for modular multilevel converters used in HVDC VSC valve applications, with a focus on how power losses are addressed in a controlled technical framework. As an amendment, it functions as a modifying document rather than a standalone specification, and it is relevant where documented evaluation, verification activities, and engineering documentation must reflect the latest published changes. It supports more consistent technical assessment and reduces ambiguity in loss-related interpretation.
Compliance applications of IEC 62751-2:2014/AMD2:2023
IEC 62751-2:2014/AMD2:2023 is typically used alongside the parent document in procurement review, design verification, laboratory evaluation, and compliance workflows for HVDC converter projects. It may be referenced when assessing modular multilevel converter valve designs, reviewing performance criteria tied to power losses, or aligning project documentation with current amendment status. For organizations managing technical compliance, it can help ensure that specifications, test planning, and conformity assessment records remain consistent with the applicable updated reference set.
Benefits of IEC 62751-2:2014/AMD2:2023
Using IEC 62751-2:2014/AMD2:2023 helps teams maintain operational consistency when working with converter-valve loss documentation and related technical validation. It supports safety-focused review, better traceability in engineering decisions, and more reliable comparison of design or test results against the current amendment set. For procurement and quality assurance teams, it can reduce the risk of relying on outdated references and improve confidence in technical compliance, especially where regulated documentation and formal review are part of the workflow.
