The invention provides a positioning method for electric network equipment with operating risk based on GIS (geographic information system) and weather information. The method comprises the following steps that electric network GIS and weather data is obtained; the electric network equipment operating in abnormal weather is positioned; the operating risks of the electric network equipment are evaluated; the operating risks of the electric network equipment are told. The method provided by the invention solves the different problem that the operating risks of the electric network equipment in an electric power system in the abnormal weather cannot be precisely positioned. A mode of combining the GIS and the weather information is used for integrally checking and positioning the electric network equipment with the operating risks in the abnormal weather, the accuracy is high, the requirement of delicacy management of the electric network safe operation is met, the guidance is provided for the electric network overhaul planning, the support is provided for discovering the electric network potential risks in each kind of abnormal weather and reducing the electric network operating risks and the fault loss in advance, and an effective analysis tool is provided for weak links of the electric network in various kinds of abnormal weather.
