Power System Transmission Modeling and Simulation.

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.
