This document contains the detailed information of the standard IEEE C37.115-2003. A standard test method, including evaluation criteria and performance measures, test scenarios for communication between intelligent electronic devices (IEDs) that implement substation integrated protection, control, and data acquisition is defined. Test scenarios are used to describe what data is exchanged between IEDs to perform a specified function that may be distributed between IEDs. All test scenarios use a standard Unified Modeling Language (UML) and a core reference model to build out an implementation.
