A system and method for verifying the coordination between generator protection and grid protection in a nuclear power plant includes an electrical simulation device, a power unit, a first junction box, a generator-transformer protection device, a second junction box, and a grid protection device. The verification method of this application verifies the coordination between the generator's grid protection and the grid system by adding voltage and current values ​​to the generator-transformer protection device and the grid protection device. The input voltage and current values ​​are calculated by the electrical simulation system, resulting in objective, accurate, and highly reliable verification results. Furthermore, the method is simple to operate, with wiring methods and current transformer polarities set entirely according to actual site conditions, enabling the detection of errors in the circuit and providing a more comprehensive verification.

The application provides a method and system for checking the cross-modal information consistency of a maintenance plan based on a large model, and relates to the technical field of big data analysis. The method comprises the following steps: identifying a target maintenance plan through a power large model, determining key maintenance content, an unstructured proportion, and an attachment type complexity; obtaining a text data complexity and a business risk index based on key maintenance content analysis, as a first checking difficulty coefficient and a second checking difficulty coefficient; determining a third checking difficulty coefficient according to the unstructured proportion and the attachment type complexity evaluation; taking the expected review time limit of the target maintenance plan as a constraint, formulating an adaptive checking depth and an adaptive checking breadth based on the first checking difficulty coefficient, the second checking difficulty coefficient, and the third checking difficulty coefficient; and performing cross-modal information consistency checking on the target maintenance plan according to the adaptive checking depth and the adaptive checking breadth. The dynamic allocation of resources for checking the cross-modal information consistency of a maintenance plan is achieved.
