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 ... -
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 ... -
Modeling and validation of losses due to unbalanced loading of stand-alone generators
(IEEE, 2017)The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal ... -
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 ... -
Power quality grid code compliance for renewable power plants in South Africa
(IET, 2019)The introduction of renewable generation to South Africa's grid has introduced challenges to the management and regulation of power quality (PQ). These have been addressed by establishing PQ compliance criteria in line ...
