The embodiment of the invention provides a fault analysis method and apparatus of an electric power information communication system based on an image database. The fault analysis method comprises the following steps: obtaining attribute information of an electric power information communication device and a power grid information system, establishing an image data model of the electric power information communication system according to the attribute information; performing retrieval in the image data model, and performing breadth diffusion analysis according to a preset depth to determine a fault influence range. By implementation of the fault analysis method and apparatus, depth analysis is performed according to the retrieval in the image database, state monitoring of the electric power information communication device can be effectively processed, and the fault influence range is confirmed to provide auxiliary support for fault level evaluation and operation and maintenance object confirmation.
