Claim 13:
14. The hierarchical health index evaluation apparatus for an intelligent substation according to claim 10, wherein
the whole-station health index calculation module comprises:
a layer-based weight calculation unit, configured to calculate a sum of device importance weights of all devices in each layer, and obtain 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
a whole-station health index calculation unit, configured to perform 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.
