Aiming at the problem of low EUEDN（Equipment Utilization Efficiency of Distribution Network） in China

taking the influence of distributed generation into account

a set of influence indicator system for equipment utilization efficiency of active distribution network is established and a value calculation method based on Pignistic probability distance is designed. Firstly

the influence indicators of capacity factor and load rate

which are the indexes reflecting the EUEDN directly

are analyzed

the differences between the influence indicator of active distribution network and passive distribution network are compared

and a set of influence indicator system for equipment utilization efficiency of active distribution network is established from three aspects of load characteristics of equipment

operation time of equipment and equipment parameters. Then

based on the Pignistic probability distance optimal evidence synthesis method

a combined weighting method based on AHP（Analytic Hierarchy Process） and entropy weight method with "deviation discount"feature is proposed

which is used to calculate the values of influence indicators. Finally

the effectiveness of the proposed influence indicator system and value calculation method is verified by case analysis.
