The application provides a pumped storage
power station protection fixed value
processing method, device, equipment and medium, relates to the
relay protection technology field of power systems, and comprises the following steps: determining fixed value combination data from a fixed value feasible region, inputting the fixed value combination data into a pumped storage
power station simulation model, simulating
multiple fault scenes, and obtaining performance data; performing
feature extraction on the performance data to obtain performance indexes; taking the fixed value combination data and the performance indexes as a
training set, training an initial performance proxy model, and obtaining a performance proxy model; standardizing the fixed value feasible region, determining a protection fixed value
population, inputting the protection fixed value
population into the performance proxy model, obtaining individual performance indexes corresponding to each individual, performing multi-objective constraint optimization
processing on the protection fixed value
population based on the individual performance indexes, and obtaining fixed value combination data actually used by a protection device. The technical scheme of the embodiment of the application can improve the reliability and intelligent level of
relay protection of pumped storage power stations.
