Demand-side energy management of a cascade mine surface refrigeration system
(North-West University, 2007)
The investigations focus on load shifting, load clipping and energy efficiency through control strategies. Load shifting is achieved by increasing the amount of work done in the Eskom non-peak period. This then results in ...
A new minimum cost model for water reticulation systems on deep mines
(North-West University, 2008)
In the past, electricity in South Africa was taken for granted. This situation suddenly changed in January 2008, when the electricity supply system threatened to collapse. Energy efficiency was suddenly brought to the fore ...
Developing ESCO procedures for large telecommunication facilities using novel simulation techniques
(North-West University, 2006)
Peak electricity demand in South Africa will exceed the available operational generation
capacity in 2007. The state utility Eskom is addressing this challenge, inter aha, with the
implementation of the Demand-side ...
Researching the long-term impact of load management projects on South African mines
(North-West University, 2006)
Eskom is currently facing an energy crisis due to the limited operational electricity generating capacity in South Africa. The historically low electricity price, the rapid growth in economy and the energy intensive nature ...
A new approach to ensure successful implementation and sustainable DSM in RSA mines
(North-West University, 2005)
In this study a new tool was developed that made new approaches possible for the successful implementation of Demand Side Management (DSM) projects. The new approaches are incorporated into a generic tool that makes it ...
The optimisation of transfer chutes in the bulk materials industry
(North-West University, 2009)
Bulk materials handling is a rapidly growing global industry. Immense challenges exist to improve the efficiency and cost effectiveness of transporting and handling bulk materials continuously. The nature and scale of bulk ...
Engineering a novel automated pump control system for the mining environment
(North-West University, 2007)
South Africa is experiencing serious electricity supply problems. A major concern is
the high peak electricity demands between 18:00 and 20:00. This peak is primarily
caused by the growing residential sector. Unfortunately, ...
The development of an improved labour planning model for mines
(North-West University, 2004)
The mining industry is the largest source of foreign income for South Africa. It is also the main source of employment in the country, for example Anglo Platinum employs approximately 40 000 employees and contractors. As ...
An automated solution to facilitate sustainable DSM in the mining environment
(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 ...
Research on reducing costs of underground ventilation networks in South African mines
(North-West University, 2006)
South Africa is currently facing a major electricity crisis due to the continuous growth in electricity demand. Eskom, the largest electricity supplier in South Africa, have enabled numerous methods to support energy ...
