    The Westcor project is intended to exploit the environmentally friendly, renewable, hydroelectric energy of the Inga rapids site in the Democratic Republic of Congo (DRC). First pass studies show that HVAC is inadequate and that conventional HVDC at 500 kV is acceptable for low loads over the long distance. For higher loads, it will be required to increase the operating voltage. First pass studies... View full abstract»

    Africa has 15% of the world's land area, 13% of the world's population, uses approximately 3% of the world's electricity but accounts for only 2% of the global industrial capacity. With an installed generation capacity of approximately 105000 MW, Africa has a relatively small power infrastructure in comparison with its geographic size and population. This paper sets out to achieve the following: i... View full abstract»

    This paper outlines a method for modulating direct current in such a way as to distribute power equally among three rather than two conductors., thus making it particularly adaptable to conversion of long AC lines to HVDC. Those principles and the resulting operating characteristics of "tripole" HVDC are then discussed as they relate to converter station design, construction and operation. Finally...

    The use of ultra high voltage direct current (UHVDC), i.e. voltages above the highest in use, 600 kV, has been found to be economically attractive for power blocks up to 6000 MW for distances above 1000 km, Furthermore the use of 800 kV as transmission voltage will be achievable within the near future with a limited amount of development work. None of the AC equipment, auxiliary equipment or contr... View full abstract»

    Conversion of one circuit of a double circuit 220 kV AC line into 100 kV, 100 MW, 6 pulse monopolar HVDC ground/metallic return while the other circuit of the same line remaining at 220 kV AC was planned in 1983, with a view to develop the in-house HVDC technology. Many options were discussed and finally concluded to go for 100 kV 100 MW, 6 pulse monopolar HVDC ground/metallic return. During the p... View full abstract»

    Systems developers and service providers in utility markets with volatile regulatory compliance conditions due to deregulation, unbundling, privatization and partial re-regulation have over the years witnessed high replacement rates for whole information and communication technology (ICT) systems and low levels of satisfaction with return on investment figures. In this paper resulting deficits in ... View full abstract»

    Power sector deregulation is a global phenomena but driven locally by a mix of complex forces peculiar to each country. Using a case-study example, this paper evaluates distribution (embedded) generation as an option for developing economies to ensure system stability and improve reliability. A methodology for evaluating distributed generation (DG) services is proposed and a framework for integrat... View full abstract»

    The environment possesses the most threat to the overall performance of overhead lines as they are continuously exposed to its harsh influences, e.g. birds, lightning, pollution and fires. These environmental influences contribute about 95% to the total transmission network faults. The quality of supply to Eskom's customers is then heavily affected, and hence strategies of combating these environm... View full abstract»

    The city of Kinshasa, capital city of the Democratic Republic of Congo, receives its electric power supply from the National Electricity Society (SNEL). The structure of Kinshasa's distribution network was inherited from its colonial period. Secondary network systems were incorporated into the main system after they emerged from new towns and villages as a consequence of the population explosion b... View full abstract»
