Harmonic emission assessment on a distribution network: the opportunity for the prevailing angle in harmonic phasors
Abstract
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 the
compliance to grid code requirement set by the distributio
n system operator. Harmonic p
hasors recorded coherently
all over the network can cause an impractical volume of da
ta. This study investigates
the opportunity to improve
existing methodologies by application of the prevailing angle in a harmonic phasor as an approach to significant
reduction of data and then demonstrate the evaluati
on of grid compliance in a network with a number of RPP
interconnected. It is shown that the unrelated dynamic nature of the different non-linear energy sources does
compromise the practical application of the prevailing har
monic phase angle. It is then concluded that the dynamic
nature of RPP necessitates continuous monitoring of grid code requirements on harmonic emission
