In the Smart Grid, protection engineers should be provided with advanced tools to execute event analysis more effectively making sure the system is restored as quickly as possible. Since the manual event analysis is a time consuming process, this paper proposes a scheme for real-time automated collecting, analyzing, archiving, and displaying of Substation Intelligent Electronic Device (IED) data generated during a power system events. How the relevant information is extracted to generate a customized report, especially considering protection engineers' needs is discussed. Several intelligent IED data analysis application tools are incorporated for the purpose of effective IED data processing. A software application named “Report Generator” is developed for the purpose of data integration and information exchange to create the report with a predefined format. A simulation case is given for more detailed description of the automation process. This solution ensures high efficiency in root-course analysis aimed at understanding and trouble-shooting relay operations, resulting in improved reliability of power system operation.
