Business case for industrial DSM maintenance
Groenewald, H.J.; Van Rensburg, J.F.; Marais, J.H. (IEEE, 2014)The performance of industrial DSM projects often deteriorates without proper maintenance. Underperforming DSM projects waste money and increase the demand for electricity from Eskom. A solution to this problem is dedicated ... -
Developing a dynamic control system for mine compressed air networks
Van Heerden, S.W.; Pelzer, R.; Marais, J.H. (IEEE, 2014)Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed via compressed air ring networks where multiple shafts are supplied with compressed ... -
Modernising underground compressed air DSM projects to reduce operating costs
Kriel, C.J.R.; Marais, J.H.; Kleingeld, M. (IEEE, 2014)Compressed air is an energy intensive utility that is frequently used in the deep level mining industry. Most compressed air networks are designed to ensure ample compressed air supply to consumers. This has created the ... -
Practical considerations in energy efficient compressor set-point control strategies
Van Tonder, A.J.M.; Marais, J.H.; Bolt, G.D. (IEEE, 2014)Compressed air supply and demand strategies have received significant attention since integrated demand management was initiated by Eskom. Due to the expensive nature of this vastly utilised energy carrier, every increase ... -
Reducing energy consumption of mine cooling systems by controlling chilled water demand of mobile cooling units
Mare, P.; Marais, J.H.; Kriel, C.J.R. (IEEE, 2014)Energy costs are increasing rapidly. Energy efficiency strategies are required to reduce electricity consumption for energy intensive operations. Cooling systems of deep level mines consume approximately 25% of their total ...
