Abstract:
in this paper, the specific protection device for Reliability Improvement options has been identified for
this case study.Reliability performance of existing distribution network with and without protection devices has been
evaluated. The economic impact of power interruption to utility and Brewery Factory estimated. The collected
interruption data analyzed and reliability of existing power distribution system is assessed. Power distribution system
with protection device along the feeder evaluated using ETAP software. Comparing scenarios using reliability
performance and protection coordination simplicity best scenario is selected. The simulation of the power distribution
models shows that the application of reclosers can improve the reliability of the overall system from 47% to 83%. The
study will be useful for power distribution system planners, load forecasting and decision makers since it presents a
concern on how much demand is available at each section of power distribution system and reliability performance of
each section can beevaluated easily. By minimizing unsold electrical energy EEU will benefits the corporation to earn
more profit.
