Abstract: An asset management method for a substation in accordance with an example embodiment of the present invention comprises steps of: generating integrity of each element of the substation based on state data and real-time monitoring data of the each element of the substation; classifying grade of the each element of the substation depending on the generated integrity thereof, and matching the each element of the substation with one of life models for each classified grade; specifying a candidate element subject to maintenance in a certain order of priority, assessing system reliability index and economic feasibility, and selecting a maintenance scenario for the each candidate element subject to maintenance; and executing maintenance by using the selected maintenance scenario, and updating assessment of the integrity of the each element of the substation as a result of the maintenance executed.

Abstract: A substation asset management method can include the steps of: determining whether to compensate a reliability model by element of the substation by comparing reliability of a reference reliability model by substation type with reliability depending on health index by element thereof generated based on state data and real-time monitoring data by element of the substation; compensating the reference reliability model by substation type and generating a unique reliability model by element of the substation as a result of the determination; evaluating system reliability and economic feasibility by maintenance scenario based on a reference system reliability model for each candidate element subject to maintenance among the elements of the substation; and drawing a maintenance scenario of the elements of the substation by using a fitness function of maintaining the substation based on the result drawn through the evaluation of the system reliability and the economic feasibility.
