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 ...
Improved event based method for harmonic impedance assessment
(IEEE, 2016)
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 ...
Attenuation effect with non-linear loads for small stand-alone grids
(IEEE, 2016)
This paper presents the effect of non-linear loads on the overall voltage quality in small powered stand-alone (islanded) systems. The iterative effect between current and voltage distortion is related to the source's ...
Testing of a predictive pole-slip protection algorithm on a real time digital simulator
(IEEE, 2016)
Predictive pole-slip protection is not implemented in commercially available protection relays. All pole-slip protection relays on the market will only trip a generator after it has pole-slipped one or more times. A ...
The effect of a reduced power quality on the energy efficiency of stand-alone generator systems
(IEEE, 2016)
It has already been thoroughly validated that the efficiency of direct online motors is susceptible towards certain power quality parameters such as voltage unbalance or harmonic voltage distortion. It can be assumed that ...
