The invention provides a 500kV generator-transformer group protection setting method and system. The method comprises the following steps: obtaining time sequence operation data of a target generator-transformer group; extracting data features in the cable time sequence operation data and the equipment time sequence operation data, and constructing a circuit topological graph of the target generator-transformer group; constructing a generator-transformer group key equipment identification model based on a convolutional neural network, and identifying target key high-voltage equipment in the circuit topological graph; acquiring equipment key parameters of all the target key high-voltage equipment and cable key parameters of the high-voltage cable, and completing protection setting calculation of all the target key high-voltage equipment and the high-voltage cable based on the equipment key parameters and the cable key parameters; calling a corresponding target setting and rechecking strategy from a preset sett
