METHOD FOR ASSET MANAGEMENT OF ELECTRIC POWER EQUIPMENT
First Claim
1. A method for asset management of power equipment, comprising steps of:
- generating health index of each sub-device of the power equipment by using state data and real-time monitoring data of the each sub-device;
compensating a reference reliability model by the each sub-device and generating a unique reliability model by the each sub-device by comparing reliability of the reference reliability model by the each sub-device and the health index by the each sub-device;
analyzing reliability by substation system reliability and reliability by economic value;
assessing priorities based on equipment sensitivity and establishing a maintenance strategy;
calculating reliability of the power equipment by applying a system relationship model between the power equipment and the each sub-device to which specific weight and failure rate are reflected;
deriving, and calculating a quotation of, a maintenance scenario by the each sub-device; and
updating the reliability model for the power equipment while updating the unique reliability model by the each sub-device by selecting a maintenance scenario by a predetermined priority and as a result of executing the maintenance.

Abstract
A method for asset management of power equipment compensates a reference reliability model by each sub-device of the power equipment and generate a unique reliability model by the each sub-device by comparing reliability of the reference reliability model by the each sub-device and the health index by the each sub-device; assesses priorities based on equipment sensitivity and establishes a maintenance strategy while analyzing reliability by substation system reliability and reliability by economic value; calculates reliability of the power equipment by applying a system relationship model between the power equipment and the each sub-device to which specific weight and failure rate are reflected; selects a maintenance scenario by a predetermined priority; and updates the reliability model for the power equipment and the unique reliability model by the each sub-device as a result of executing maintenance.
