    • Assessment of the national DSM potential in mine underground services 

      Den Boef, Martinus (North-West University, 2003)
      ESKOM is moving towards a price structure for electricity which reflects, as far as possible, the real cost of generation. It is called real time pricing (RTP). ESKOM developed this cost structure to coax customers to ...
    • Automated control of mine dewatering pumps 

      Smith, Tinus (2014)
      Deep gold mines use a vast amount of water for various purposes. After use, the water is pumped back to the surface. This process is energy intensive. The control is traditionally done with manual interventions. The purpose ...
    • An automated solution to facilitate sustainable DSM in the mining environment 

      Steyl, Jacob Petrus (North-West University, 2008)
      South Africa is experiencing a serious electricity supply problem. This problem is expected to persist until at least 2012. During the winter of 2006 load shedding and electricity supply-cuts started occurring in the Western ...
    • Comparison between automated and manual DSM pumping projects 

      Richter, Rudolph Petrus (North-West University, 2008)
      The purpose of this dissertation is to identify the best alternative method of load shifting on clear water pumping systems in the mining industry. This can be done through a comparison analysis between manual and automated ...
    • Demand side management on an intricate multi-shaft pumping system from a single point of control 

      Thein, Shane (North-West University, 2007)
      Eskom, the sole supplier of electricity in South Africa is facing an energy crisis. This is due to the steady increase in demand for electricity in South Africa. Low electricity prices in South Africa have helped the ...
    • Developing a dynamic control system for mine compressed air networks 

      Van Heerden, Schalk Willem (2014)
      Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed in two typical fashions. Firstly, direct pipe feed systems for single shafts or ...
    • Development of an energy management solution for mine compressor systems 

      Du Plessis, Johan Nicolaas (North-West University, 2010)
      Eskom is under increasing pressure to provide reliable and sustainable electricity. Demand Side Management (DSM), offers a short– to medium–term solution to this problem. During 2009, the mining sector consumed approximately ...
    • DSM strategy for national water pumping systems 

      Nortjé, André (North-West University, 2012)
      The continual increase in electrical energy demand in South Africa has resulted in a precariously low reserve margin in supply from the primary utility, Eskom. This resulted in extensive load shedding throughout the country. ...
    • A dynamic optimal control system for complex compressed air networks 

      Van Heerden, Schalk Willem (North-West University (South Africa) , Potchefstroom Campus, 2016)
      Mines use large compressed air networks to supply shafts and processing plants with compressed air. These networks can be complex where multiple compressors are located at different locations. To add to the complexity of ...
    • Electricity cost optimisation of a surface potable water pump system 

      Slade, Michael Peter (North-West University, 2007)
      South Africa is fast approaching an era where its electrical energy demand will surpass the generating capacity of it's primary utility. The reason for this is due to the fact that over the past 10 years, the economic ...
