IEC 62751-2:2014

IEC 62751-2:2014 provides technical guidance on power losses in voltage sourced converter (VSC) valves for high-voltage direct current (HVDC) systems, with a focus on modular multilevel converters. It is relevant for engineers and compliance teams evaluating converter performance, loss assessment, and documented evaluation within HVDC projects. For organizations comparing equipment, validating designs, or supporting procurement review, the document helps frame a consistent technical reference for assessing operating characteristics and supporting engineering documentation.

Overview of IEC 62751-2:2014

IEC 62751-2:2014 addresses the power losses associated with VSC valves used in HVDC systems, specifically for modular multilevel converter arrangements. As an original edition, it serves as the primary technical reference for understanding how these converter valves are considered in performance analysis and technical review. The document is most useful where measured or calculated losses must be handled in a repeatable way during technical validation, design comparison, or conformity assessment preparation.

Compliance applications of IEC 62751-2:2014

This document is commonly used in engineering workflows involving HVDC converter stations, power electronics assessment, and laboratory evaluation of converter valve performance. It may support procurement specifications, supplier documentation review, and verification activities where loss-related data must be interpreted consistently. In project settings, IEC 62751-2:2014 can be a useful compliance reference for technical assessment, especially when teams need to align design assumptions, testing workflows, and operational consistency across modular multilevel converter solutions.

Importance of compliance with IEC 62751-2:2014

Using IEC 62751-2:2014 as part of a structured compliance workflow helps reduce ambiguity in loss-related evaluation and supports more reliable engineering validation. That can be important for risk management, performance comparison, and procurement decisions where converter efficiency and documented technical behavior influence acceptance. It also supports testing consistency and conformity assessment preparation by giving stakeholders a common basis for review, which can improve quality assurance across design, verification, and system integration activities.
