Abstract:
In this research it's intended to reduce the number of line trips by
improving the radial feeders reliability of “KHARTOUM NORTH
DISTRIBUTION AREA” 11KV radial feeders which it's tripped frequently by
using three scenarios.The first scenario by installing auto reclosers &
sectionalizers devices in these feeders and connect these devices with SCADA
system. The second scenario by removing the uninsulated conductor wires of
the all radial feeders 11 KV & changing them with insulated wires 11kv. The
third scenario by changing the configuration of the overhead line radial
feeders to underground cable system.
The distribution system, lines faults, autorecloser, sectionlizer and the smart feeder operation are defined. The comparison between the three scenarios is discussed with calculating the reliability indices by using matlab & GIS softwares.
