1. A method for operating an electrical power automation system that includes a plurality of interconnected logical objects, the method comprising:

  • evaluating, with a computer of the electrical power automation system, a data file associated with the automation system to identify information descriptive of the plurality of interconnected logical objects, wherein the plurality of interconnected logical objects include a control device, a relay device, a measurement device, and a protection device;

    responsive to evaluating the data file to identify the information, automatically generating, with the computer, a fuzzy cognitive map that models an interdependence of the plurality of interconnected logical objects upon one another based upon the information, wherein the fuzzy cognitive map includes a plurality of nodes each representing one of the plurality of interconnected logical objects and a plurality of links each representing an interdependence between two logical objects of the plurality of interconnected logical objects,where respective weights are automatically generated for the plurality of links based upon data extracted from an extension of the data file that comprises a plurality of entries each storing a value corresponding to a weight of a link, while generating the fuzzy cognitive map to indicate a degree of interdependence such that a first interdependence between a first logical object and a second logical object is greater than a second interdependence between a third logical object and a fourth logical object,where the first logical object and the second logical object are linked to one another by a first link having a first weight and the third logical object and the fourth logical object are linked to one another by a second link having a second weight, and where the first weight is greater than the second weight;

    identifying, with the computer, a non-ideality for a node, the non-ideality associated with at least one of the plurality of interconnected logical objects; and

    selecting, with the computer, the at least one of the plurality of interconnected logical objects associated with the non-ideality and selecting at least one other of the plurality of interconnected logical objects and calculating, with the computer, an indirect effect and a total effect on the at least one other of the plurality of interconnected logical objects and reporting a qualitative value of the indirect effect and the total effect to an operator of the computer.
