Claim 10:
11. The hierarchical health index evaluation apparatus for an intelligent substation according to claim 10, wherein
the device health index calculation module comprises:
a data packet obtaining unit, configured to obtain a data packet exchanged between the device and the another device;
a correlated device list adding unit, configured to add the another device to a correlated device list of the device based on IP address and MAC address information of the data packet, wherein the device is also added to a correlated device list of the another device;
a sorting unit, configured to sort a correlated device in the correlated device list of the device in ascending order based on a basic health index of the correlated device to obtain a sorted correlated device;
a correlation weight determining unit, configured to determine a correlation weight of the correlated device based on a quantity of correlated devices in the correlated device list; and
a device health index calculation unit, configured to correct the basic health index of the device based on the basic health index and the correlation weight of the sorted correlated device to obtain the health index of the device.
