Abstract

Overview

IEC 60050-551-20:2001 is an integral part of the International Electrotechnical Vocabulary (IEV), focusing specifically on Power Electronics and Harmonic Analysis. Published by the International Electrotechnical Commission (IEC), this standard plays a critical role as a horizontal standard under IEC Guide 108, providing universally accepted terminology and definitions in the field of harmonic evaluation in power electronics systems.

Key Topics

The standard covers a comprehensive terminology glossary related to harmonic analysis of power electronics, including but not limited to:

Fundamental Component: The sinusoidal part of a periodic waveform corresponding to its own frequency.
Reference Fundamental Component: The sinusoidal component used as a baseline for comparing all other frequency components.
Fundamental Frequency: The frequency of the fundamental component.
Harmonic Frequency: Frequencies that are integer multiples of the fundamental frequency or reference fundamental frequency.
Interharmonic Frequency: Non-integer multiples of the reference fundamental frequency, often associated with complex waveform distortion.
Harmonic Component: Sinusoidal parts of a periodic quantity corresponding to harmonic frequencies.
Interharmonic Component: Sinusoidal parts linked with interharmonic frequencies.
Harmonic Order: The ratio of a sinusoidal component’s frequency to the fundamental frequency.
Sub-Harmonic Components: Interharmonic components with harmonic order less than one.
Total Distortion Content: The sum of all harmonic and interharmonic components after removing the fundamental or reference fundamental component from a waveform.
Harmonic Residue: The sum of all harmonic components, expressed as a function of time.

These terms are defined in multiple languages, including French, English, Chinese, German, Spanish, Italian, Japanese, Polish, Portuguese, and Swedish, to support international standardization efforts.

Applications

IEC 60050-551-20:2001 is essential for professionals working in:

Power Electronics Design and Testing: Ensuring components and systems meet harmonic distortion criteria.
Harmonic Measurement and Analysis: Establishing accurate, consistent terminology for measurement methodologies of harmonics and interharmonics in electrical systems.
Electrical Grid Management: Understanding and specifying standards for harmonic disturbances in power distribution networks.
Research & Development: Supporting academic and industry R&D efforts in power quality and signal analysis in power electronics.
Regulatory Compliance: Assisting national and international bodies in aligning regulations and testing requirements for harmonic emissions in electrical equipment.
Standardization Bodies: Maintaining consistency in language and definitions across various related standards and technical documents.

Related Standards

IEC 60050-551-20:2001 is part of the broader IEC 60050 series addressing electrotechnical vocabulary. It directly relates to other standards within power electronics and power quality such as:

IEC 61000 series – Electromagnetic compatibility (EMC) standards dealing with harmonic emissions and immunity.
IEC 60050-551 – General power electronics vocabulary.
IEC Guide 108 – Framework for horizontal standards, ensuring harmonized terminology across technical fields.

Adherence to IEC 60050-551-20 supports interoperability and clarity across industry sectors, facilitating better communication and technical understanding of harmonic phenomena in power electronics.
