Hierarchical evaluation method and device for reliability of power distribution network facility and computer equipment

The invention relates to a power distribution network facility reliability hierarchical evaluation method and device and computer equipment, and the method comprises the steps: carrying out the hierarchical processing of a power distribution network facility according to the reliability evaluation granularity of the power distribution network facility, so as to obtain a plurality of evaluation objects of different evaluation hierarchies; based on the reliability indexes of different types of evaluation objects of the current evaluation level, obtaining the reliability index of the evaluation object corresponding to the previous evaluation level; and obtaining the reliability index of the power distribution network facility according to the reliability indexes of the evaluation objects corresponding to the multiple evaluation levels. Therefore, reliability hierarchical evaluation of the power distribution network facilities is realized, reliability evaluation requirements of diversity and complexity of the pow
