Industrial and Commercial Power System Harmonic Studies: Introduction to IEEE Standard 3002.8-2018

This article introduces the latest IEEE standard 3002.8-2018,
Recommended Practice for Conducting Harmonic Analysis Studies of Industrial and Commercial Power Systems
. The standard replaces IEEE Standard 399 (
IEEE Brown Book
) Chapter 10 “Harmonic Analysis Studies” with significant enhancements and additions. The new standard addresses requirements for performing power system harmonic-analysis studies in industrial and commercial power systems due to increasing load, distributed energy generation, storage nonlinearities, and control devices. The recommendations on developing system models to include various harmonic sources and electrical equipment and devices, preparing required data for modeling and studies, validating model and data, selecting study cases, and analyzing study results and outputs are discussed in detail in the standard. The common mitigation solutions for harmonic issues are presented and discussed. Features of the computer-aided tools used to perform harmonic-analysis studies are reviewed. The new standard references the latest IEEE Standard 519-2014,
Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems
, for harmonic restrictions at the point of common coupling (PCC) as well as the modeling and limits to interharmonics. Several examples are provided to demonstrate harmonic issues and illustrate the analysis process through studies for mitigations. The authors of this article are the cochairs of the IEEE Standard 3002.8-2018 Working Group.
