On the assessment of harmonic emission in distribution networks: opportunity for the prevailing harmonic phase angle
(IEEE, 2016)
Harmonic emission assessment for Grid Code compliance of Renewable Power Plants (RPP) has to be fair and pragmatic. The CIGRE C4.109 method lacks the ability to determine which harmonic currents have a positive or negative ...
Harmonic emission assessment on a distribution network: the opportunity for the prevailing angle in harmonic phasors
(IET, 2017)
Harmonic emission assessment in high-voltage networks with a number of renewable power plants (RPP)
interconnected is challenging. A sound scientific methodology readily accessible to engineers is needed to validate ...
Network resonance detection using harmonic active power
(IEEE, 2018)
Resonances in electrical distribution systems can result in amplification of harmonics, which is undesirable in electrical networks. To avoid intrusive measurement techniques, in the majority of the cases network modeling ...
A discriminative approach to harmonic emission assessment
(IEEE, 2015)
With the onset of renewable power sources onto the network, such as Photovoltaic power plants contributing to Total Harmonic Distortion (THD) in voltage, a methodology to quantify their contribution to the THD in voltage ...
Evaluation of harmonic distortion from multiple renewable sources at a distribution substation
(IEEE, 2017)
Harmonic emission assessment in a distribution network with existing background voltage harmonics is a challenge for Renewable Power Producers (RPP) aiming to achieve grid code compliance. Dynamic interaction of harmonic ...
Measurement uncertainty of current harmonics during the assessment of compliance to grid code requirements
(IEEE, 2018)
This paper improves the impact of measurement uncertainty on harmonic grid code compliance assessment by characterization of the current transformers at a renewable power producer. Field data was collected to evaluate the ...
Impact of aggregation interval on harmonic phase angle measurements
(IEEE, 2018)
The aggregation principles of IEC 61000-4-30 is a well-known concept implemented in Power Quality (PQ) recorders. Only rms data is retained. Harmonic emission assessment requires the analysis of harmonic phasors. Continuous ...
