A New Measurement Method for the Detection of Harmonic Sources in Power Systems Based on the Approach of the IEEE Std. 1459–2000

A Distributed Measurement System for Power Quality Monitoring

“…1.The voltage and currents harmonic levels and phase angles. Different PQ indices proposed in [5,6] may be evaluated by using aforementioned parameters.…”

A New Assessment for the Total Harmonic Contributions at the Point of Common Coupling

“…Since there are some ambiguities in quantifying the contributions of the utility and customers using the complex number in equations (2)(3)(4)(5), it is reasonable to refer to scalar quantities using the scalar projection onto the harmonic current or voltage at the PCC. Using the dot product of complex vectors, the individual harmonic current impact , and the individual harmonic voltage impact , of feeder k at the h th harmonic frequency can be described by the following equations:…”

“…A qualitative Yes or No answer is not sufficient in this case, since all the suspicious loads including linear loads are likely to create voltage distortions at the PCC. Methods using harmonic active power or nonactive power components of the apparent power provide only positive or negative value to detect the dominant harmonic sources upstream or downstream from metering sections [1,2]. Such approaches cannot provide correct information about the identification of the harmonic sources in some practical situations [2].…”

Instantaneous approach to IEEE Std. 1459 power terms and quality indices

“…1459 for the non-fundamental effective apparent power (S eN ). Works presenting redefinitions of the power magnitudes or novel power quality indices can be found in the literature [8][9][10][11][12][13][14][15]. In Ref.…”
