The adaptive predictive control of an energy efficient central water heating system applied in the South African commercial sector
(North-West University (South Africa), Potchefstroom Campus, 2016)Since the introduction of load shedding in the latter part of 2007, Eskom, the electrical utility of South Africa, have been forced to implement energy efficient and energy management measures to ensure the stability of ... -
Assessing the barriers companies face towards the implementation of corporate energy efficience strategies
(North-West University, 2012)Global climate change and the electricity supply constraints could possibly be one of the utmost strategic issues facing businesses and consumers of all sizes currently in South Africa. Energy Efficiency is the ability to ... -
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 conceptual design of an integrated energy efficient ore reduction plant
(2014)This study explores ways to determine the energy efficiency of a pyrometallurgical ore reduction plant and measures to improve it. The feasibility of building a commercial plant - that is more energy efficient, has a low ... -
Developing a dynamic operational energy management strategy for energy intensive industries
(North-West University (South Africa) , Potchefstroom Campus, 2017)Fossil fuels are likely to supply most human energy needs for the 21st century. However, these fuels are exhaustible and have adverse environmental effects when combusted. To reduce the negative environmental effects, the ... -
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 ... -
The effect of controlling main ventilation fan inlet guide vanes for a deep level platinum mine to reduce electrical costs
(North-West University (South Africa) , Potchefstroom Campus, 2017)Because of the annual electricity increases from Eskom that are above inflation, and the mining industry that is struggling to survive due to continuous increase in operating cost, the low selling price of precious ... -
Efficient energy-aware controller placement in software-defined wireless sensor networks
(North-West University (South Africa), 2022)A centralized controller in the Software-defined Wireless Sensor Networks (SDWSN) environment poses a single point of failure and is inapt for a large-scale network. As leverage, multiple controllers have been introduced ... -
Energy efficiency and the law: a multidisciplinary approach
(ASSAf, 2015)South Africa is an energy-intensive country. The inefficient use of, mostly, coal-generated energy is the cause of South Africa’s per capita contribution to greenhouse gas emissions, pollution and environmental degradation ... -
Energy efficiency opportunities in mine compressed air systems
(North-West University, 2009)Demand Side Management (DSM) is one of the most viable and sustainable short term methods to address the shortfall in electricity generation in South Africa. This is because DSM projects can be implemented relatively ...
