Claim 4:
5. The method according to claim 1, wherein the obtaining a whole-station health index of an intelligent substation based on a layer-based health index of each layer and a sum of device importance weights of each layer comprises:
calculating a sum of device importance weights of all devices in each layer, and obtaining a layer-based weight of a layer-based health index of a layer based on a proportion of a sum of device importance weights of the layer to a sum of device importance weights of all layers; and
performing weighted summation on the layer-based health index and a layer-based weight of each layer to obtain the whole-station health index of the intelligent substation.
