A New Assessment Method of Customer Harmonic Emission Level

2010 Asia-Pacific Power and Energy Engineering Conference, 2010
Considering the influences of harmonic parameter changes both in customer and system sides of the point of common coupling (PCC), the paper proposes an assessment method for customer harmonic emission level based on the dominant fluctuation filtering principle. The concept of fluctuation ratio of harmonic volt-ampere characteristic at PCC is introduced

Harmonic emission level estimation based on measurements at the point of evaluation

2011 IEEE Power and Energy Society General Meeting, 2011
Two methods for determination of harmonic emission levels at the point of evaluation are discussed in this paper. A method based on harmonic voltage and current phasor measurements is compared with the method based on long duration measurements of harmonic current and voltage magnitudes.
