Claim 9:
10. A hierarchical health index evaluation apparatus for an intelligent substation, wherein the apparatus comprises:
a device basic health index calculation module, configured to obtain a basic health index of a device based on static information and dynamic information of the device;
a device health index calculation module, configured to obtain a device correlation based on a communication connection relationship between the device and another device, and correct the basic health index of the device based on the device correlation to obtain a health index of the device;
a layer-based health index calculation module, configured to obtain a layer-based health index of a layer based on a device health index and a device importance weight of the layer;
a whole-station health index calculation module, configured to obtain 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; and
a global regulation module, configured to regulate the intelligent substation based on a health index of each device in the intelligent substation, the layer-based health index of each layer, and the whole-station health index.
