Evaluation of harmonic distortion from multiple renewable sources at a distribution substation
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 ...
Improved event based method for harmonic impedance assessment
The quantification of harmonic emission requires an accurate model of the network harmonic impedances. A number of techniques have been proposed for the assessment of the network harmonic impedances to be practical and ...
On the assessment of harmonic emission in distribution networks: opportunity for the prevailing harmonic phase angle
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 ...
A discriminative approach to harmonic emission assessment
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 ...
Continuous harmonic impedance assessment using online measurements
The quantification of harmonic emission requires an accurate representation of the network harmonic impedances. A number of techniques have been proposed to make the assessment of the network harmonic impedances practical ...
On the remote calibration of voltage transformers: validation of opportunity
Remote calibration of instrument transformers seems possible if sufficient certainty in field measurements can be achieved. This opportunity, until now, was only investigated from a theoretical point of view and in this ...
