A pumped storage power station protection setting value processing method, device, equipment and medium

Abstract

This invention provides a method, apparatus, equipment, and medium for processing protection settings in pumped storage power stations, relating to the field of power system relay protection technology. The method includes: determining setting combination data from the feasible setting domain and inputting it into a pumped storage power station simulation model to simulate multiple fault scenarios and obtain performance data; extracting features from the performance data to obtain performance indicators; using the setting combination data and performance indicators as a training set to train an initial performance proxy model to obtain a performance proxy model; standardizing the feasible setting domain to determine a protection setting population and inputting it into the performance proxy model to obtain individual performance indicators for each population; and performing multi-objective constraint optimization processing on the protection setting population based on these indicators to obtain the setting combination data actually used by the protection device. The technical solution of this invention can improve the reliability and intelligence level of relay protection in pumped storage power stations.
