The application relates to a relay protection misoperation root cause analysis method, device, equipment, medium and program product. The method comprises the following steps: in response to detecting a relay protection misoperation event, acquiring a corresponding observation data set; extracting and locking an exogenous noise vector of the relay protection misoperation event by inverse operation of a mixed driving structure equation; calculating average causal effects of each environmental state variable on relay protection action behavior, and generating a root cause quantitative analysis result according to the average causal effects; receiving an intervention operation instruction input by a user for a target environmental state variable, keeping the locked exogenous noise vector unchanged, inputting the modified target environmental state variable into a structural causal model, performing forward prediction and waveform synthesis through a mixed deduction engine, generating a virtual fault waveform and corresponding relay protection logic simulation results; and comparing the time domain waveform and the action logic to generate a comparison result. The method can quickly reproduce an accident scene and quantitatively locate a misoperation root cause.

This invention relates to the field of logic simulation and decision support for nuclear power units, and particularly to a lightweight simulation analysis system and method for the consequences of power outages in nuclear power units. The system includes an electrical node module, a logic judgment module, and a simulation analysis module. The electrical node module constructs an electrical node model and defines the attributes and electrical logic relationships of the electrical nodes. The logic judgment module performs logical judgments to determine the state of the electrical nodes. When the simulation analysis module receives a power outage signal from an electrical node, it queries the downstream electrical nodes of the out-of-power node and transmits the power outage signal to the downstream electrical nodes. It then performs logical judgments on the out-of-power node and the downstream electrical nodes, and provides the power outage status of the downstream electrical nodes based on the judgment results. This invention uses the simulation analysis module to simulate and analyze power outage faults in nuclear power plants. Authorized users can perform simulation operations via the Internet, improving the flexibility and efficiency of the simulation system.
