The invention relates to a rapid fault positioning and repair method of a power area. The method comprises the following steps of a) combing related data such as geographic information, public variable capacity, user condition and photovoltaic power generation of the area according to information general survey data of a low-voltage area, respectively generating a two-dimensional code of each area administered by a substation according to related data possessed by each area, and collecting to form a book according to the two-dimensional code corresponding to each area; and b) finding the corresponding two-dimensional code by an emergency maintainer according to repair demand and a numbering catalogue of the area once a power fault occurs in an area under administration. By the rapid fault positioning and repair method, the related basic information is understood, meanwhile, a public variable power point to the area is directly positioned and navigated by a function of wechat scanning of a mobile phone, and accurate and rapid power repair is achieved. The rapid fault positioning and repair method has the characteristics of simplicity, high reliability and the like, the fault can be rapidly positioned, and the repair time is saved.
