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

This paper introduces the latest IEEE Std. 3002.8 – 2018 “Recommended Practice for Conducting Harmonic Analysis Studies of Industrial and Commercial Power Systems”. The standard replaces IEEE Std. 399 (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 non-linearities and control devices. 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. Common mitigation solutions for harmonic issues are presented and discussed. Features of computer aided tools that are used to perform harmonic-analysis study are reviewed. The new standard references to the latest IEEE Std. 519–2014 “Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems” for harmonic restrictions at PCC, and modeling and limits to interharmonics. Several examples are provided to demonstrate harmonic issues and illustrate analysis process through studies for mitigations. The authors of this paper are the co-chairs of IEEE Std. 3002.8-2018 working group.
