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 ... -
Evaluation of system losses due to harmonics in medium voltage distribution networks
(IEEE, 2016)Power system harmonics are a known cause to failure, disoperation or premature aging of customer's equipment. It also causes additional losses in a distribution network that influence the planning and design of future ... -
Financial model for energy efficiency projects in the mining industry
(Elsevier, 2018)The impact of industrial EE projects have previously been understated by the omission of non-energy benefits (NEBs). As a result, several fruitful projects have not been implemented which could have dire consequences for ... -
Induction motor efficiency test methods: a comparison of standards
(IEEE, 2017)Improved efficiency is the task of the hour. Environmental challenges, which include climate change, global warming and greenhouse gas emission have been fuelling the need to increase energy efficiency in electrical rotating ... -
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 ... -
A systematic decision support system to objectively evaluate retrospective energy efficiency modelling options
(UCT, 2019)Tax incentives are one of the methods used by the South African government to incentivise energy efficiency. One of these incentives is Section 12L of the Income Tax Act (1962), which allows a significant tax deduction as ...
