A method and device automatically extract, to a maximum extent, reliability-relevant information from a Substation Configuration Description (SCD) file describing an electric power transmission or distribution substation. The information in the SCD file is used to identify the physical topology of a communication network of a Substation Automation (SA) system, and all dataflow relating to a given SA functionality or Logical Node (LN). An LN reliability measure for the latter is calculated, involving reliability indications specific to each element or device participating in the dataflow. A number of LN reliability measures are consolidated to produce an overall reliability for the SA system architecture or communication network topology. The method and tool minimize the engineering effort required to perform a reliability calculation, and thus allow comparing the reliability of different SA architectures with minimal effort and intervention of a reliability engineer.
