    Abstract: Introduction was made to the typical connection modes including overhead line and cable line of domestic medium voltage distribution network. Taking the system parameters of somewhere of Suzhou as an example, this paper used the software DIgsilent/Powerfactory to calculate the power distribution reliability index of various typical connections. The average service availability index (ASAI) and the system ENS-LP were taken as the indexes basis of power distribution reliability to analyze the influence of line segment, load balance, load density and distribution automation on power supply reliability of 7 kinds of typical connection modes in medium voltage distribution network. The analysis result provides references for the related industry personnel.
    Key words: medium voltage distribution network; typical connection mode; reliability analysis
