The invention discloses a quantitative identification method for a transfer power supply weak ring influencing power distribution network fault recovery, which comprises the following steps: S1, modeling a main distribution network, and selecting a starting point; s2, calculating a bus security load; s3, calculating the total recovery load of the feeder line of the single transfer path; s4, calculating a multi-wheeling path recovery total load; s5, calculating the primary recovery rate of the load of the transformer substation; s6, judging whether calculation of all the substations is completed or not, and if calculation of all the substations is not completed, repeating the steps S1 to S5; s7, sorting the substations according to the primary load recovery rate; S7, sorting the substationsaccording to the primary load recovery rate; and S8, according to the threshold value, carrying out positioning and strategy improvement on the weak link. The invention provides a quantitative identification method for a transfer power supply weak ring influencing power distribution network fault recovery, which can perform quantitative calculation on the power grid transfer power supply weak ring and provide a basis for power distribution network planning, regulation and control and power grid transformation.
