Dynamic load-shedding analysis for enhancement of power system stability for the Lesotho 132 kV transmission network
(North-West University (South Africa), 2019)In the past two decades, the Lesotho power system load demand increased from below 72 MW to 150 MW. This steep load increase means that the country's power generation of 72MW from hydro-power generators installed at 'Muela ... -
The elimination of electrical power limitations in the production section of a South African coal mine to facilitate additional production improvements
(North-West University, 2006)Sasol Mining embarked on a renewal process during the beginning of 1998. The objective of this renewal process was based on a very clear case for change - Sasol Mining had to improve on its profitability as a coal mining ... -
Improving the power quality on medium voltage power lines
(North-West University, 2006)The purpose of an electrical power system is to deliver energy to consumers. This should be done with the utmost reliability and economy. When power outages occur the normal routine of society is disrupted. A power system ... -
An investigation into the occurrence of ferroresonance in small distribution transformers in South Africa
(North-West University (South Africa)., 2022)In 2019, an article published by Geldenhuys and Padayachee reported unexpected overvoltages during the commissioning phase of distribution transformers. Consequently, resonance was reported as the cause of overvoltages on ... -
Research into specific numerical protection maloperations
(North-West University, 2012)High voltage transmission system availability and system security are key performance criteria for electricity utilities worldwide. System disturbances need to be cleared quickly and accurately in order to minimise the ... -
Studies on motor bus transfer challenges for the ancillary equipment of a large thermal power station
(North-West University (South Africa), 2021)This study considers the high-speed motor bus transfer system at Kendal Power Station. A highspeed motor bus transfer system is used to transfer motors from one source to another source under controlled or emergency ... -
Subtransmission power system amelioration through increased power transfer
(North-West University (South Africa)., 2022)This dissertation aimed to present considerations and solutions for the amelioration of subtransmission power systems through increased power transfer by reviewing various infrastructure technologies and solution approaches. ... -
Utilizing waste energy from a submerged arc furnace at a ferrochrome smelter plant
(North-West University (South Africa) , Potchefstroom Campus, 2015)In South Africa the current electrical energy crisis and the possibility of carbon tax forces ferrochrome (FeCr) smelters to improve the efficiency of their plants and to reduce carbon emissions at the same time. This ...
