Abstract

Reliability is a key aspect of power system design and planning. This work aims to evaluate and improve the reliability of a power distribution network in Baghdad city. The minimal cut set method has been adopted for reliability evaluation. Evaluating the reliability requires calculating and evaluating a set of reliability indices. In this research, the reliability indices are calculated for Al_Mansour 11kV distribution network in Baghdad city. According to these indices several improvements have been proposed and simulated on the network as follows:

  • Adding N/C manually switches in the network for isolating fault areaand restoring the service to the remaining parts.
  • Adding N/O manually switches to interconnect feeders and providealternative supply.
  • Replacing the manually switches by remotely controlled or fullyautomated switches with fault indicators to reduce interruption times.
  • Replacing the overhead lines by underground cables to reduce the faultrates. The software CYMDIST version 7.1 has been used as a tool for the simulation of the distribution network and performing the required analysis.
