Abstract

The present invention discloses a self-service diagnosis method for power system faults based on conversational reasoning and generation, including the following steps: receiving and processing various types of data from the power system, processing multimodal data, and providing reliable input for subsequent reasoning engines through standardized processing; after receiving the multimodal data of the power system, performing intelligent reasoning and diagnosis of the fault; and promptly feeding back the diagnosis results, fault analysis reports and solutions generated by the reasoning engine to the operator or automation system. The present invention utilizes the conversational reasoning function of a large language model to achieve multi-round interactive diagnosis. The system actively asks key questions, dynamically adjusts the diagnosis process according to the feedback from the operator, and gradually locates the cause of the fault. The present invention introduces a dynamic knowledge generation mechanism to retrieve and integrate external knowledge resources, such as technical documents and fault reports, in real time. Even in the face of unknown faults, the system can generate new reasoning paths and provide effective fault diagnosis suggestions.
