The invention discloses a city elastic power distribution network restoration capacity assessment method. The method specifically comprises five steps, wherein in the firs step, city power distribution network power supply partitions are divided; in the second step, a partition power distribution network elastic assessment system is constructed; third, an AHP (analytic hierarchy process) is utilized to determine all index weights; in the fourth step, a typical region is selected for assessment; and in the fifth step, the restoration capacity of the typical region is judged. According to the method, an elastic power distribution network assessment system is constructed scientifically and systematically from the three dimensions of prevention stage, permeation stage and restoration respectively; and through establishment of the assessment system, emergency preparation conditions of an enterprise are analyzed, advantages and disadvantages in the emergency management and emergency abilityconstruction process are discovered, existing problems are deeply analyzed, improvement suggestions and the construction direction are proposed, finally assessment and construction are organically combined, and a scientific basis is provided for enterprise investment and resource reasonable allocation.
