PURPOSE:To facilitate the indication of data and the understanding of the contents of data processing by providing a unit element level data layer and a summarized element level data layer to the data base and by providing a processing layer to an operation processing means corresponding to each data layer consisting of the above unit element level data layer and the above summarized element level data layer. CONSTITUTION:An equipment data layer 11 is a unit element level data layer describing the data that sorts the equipment constituting a power system as a unit element. To a relay data layer 13 defined data of a protection relay is described. A substation level data layer 12 is a summarized element level data layer, in which the unit element belonging to an equipment data layer 11 is abstracted by the macroelements on a substation level. On the other hand, an operation relay data layer 14 is a layer to manage the data concerning the protection relay. An accident information processing layer 15 has a function to manage the accident information inputted from outside. |
