Medium voltage distribution network reliability evaluation method based on fault mode consequence analysis

The invention discloses a medium-voltage power distribution network reliability evaluation method based on fault mode consequence analysis. The method comprises the following steps: innovating a segmented network model through key facilities and a topological relation thereof; enumerating the influence on each load point when each section of network fails; calculating reliability indexes of the load point and the system; and a future state reliability evaluation method is innovated for long-term rolling prediction. Failure frequency and repair duration of the facility are comprehensively investigated, reliability indexes of each load point and the whole system are determined, a failure mode consequence analysis table is formed, and through the evaluation method, evaluation accuracy is improved, reliability of power supply of regions, feeder lines and terminal users is promoted, and reliability of power supply is improved. Therefore, the overall operation efficiency of the medium-voltage distribution network a
