        Abstract: The distribution network power distribution reliability directly impacts on users’ power quality. This paper adopted the power system software CYME to carry out the power network modeling analysis and researched on the power distribution reliability of different power supply radius and different typical network structures. Aiming at an actual power distribution network example, this paper analyzed the power distribution network reliability situation of different switch actuation time. From the reliability corner of each load point, this paper found the load point of inferior reliability in the distribution network, proposed a specific net rack optimization scheme, which provides references for the reliability assessment analysis and application in the distribution network.
        Key words: distribution network; reliability assessment; software CYME; planning
