The project describes the plan for the extension of the transmission and distribution network to supply the Ledig and Bosok area in the North West Province in South Africa. The growth ramp in the area as a result of industrialization, commercialization and electrification will result in an overloading condition if supplied from the existing network. The objectives are to improve, rehabilitate, strengthen and extend the electrical power transmission system within the North West and to cater for the anticipated load growth for the next few years. Power transmission plarming starts with a forecast of anticipated future load requirements of both demand and energy. The detailed power survey for assessing category wise rate of growth of consumption is carried out for the residential, commercial and industrial loads. It will start with a load study of the distribution system, to be able to anticipate how much power must be delivered. The design is inclusive of number of circuits for each route, power transformer configuration, high voltage and low voltage rating of the lines and the layout of the substation equipment like bus bars, circuit breaker configuration, rating of all transformers, isolators, surge arrester and protective relay schemes that will be used. The data gathered will be consolidated by producing a schematic diagram (one line diagram) and station electric diagram of the substation. A load study will be conducted on the transmission network to see the impact of the extension on the existing grid. A voltage study will be conducted on the distribution network to ensure that all load a supplied with the specified limits, which is ± 5% of the rated voltage. If the impact on the rest of the network is too compromising or the load are supplied outside the given tolerance, the design will be re-engineered until we find a design that will lead to a efficient and effective system (old and new combined). The starting point will be the load data which will be used to determine the total power that needs to be supplied to the area. The total MV A will help in selecting the system's voltages levels, kVA ratings of equipment and amount of power that needs to be delivered to the area under study. The work starts with a transmission load study so as to be able to develop a methodology for power transmission quality value based model that will allow determining a reliable solution between utility side investment and customer side improvement.
