Electric power information system fault diagnosis system

The invention discloses a power information system fault diagnosis system, which relates to the technical field of power grid fault diagnosis and comprises a model construction module, an information acquisition module, an information processing module, a fault diagnosis module and a threat evaluation module. The information processing module is used for carrying out word segmentation processing on an alarm information text, then embedding semantic features, sentence features and position features into the alarm information text, adding the three features to form a model input vector, inputting the model input vector into a power grid fault diagnosis model through the fault diagnosis module, and carrying out diagnosis on a power grid fault. And outputting a diagnosis result. End-to-end power grid fault diagnosis is realized, and the labor cost is greatly saved; the threat evaluation module is used for calling operation parameter information of the corresponding fault equipment and a historical fault analysis
