Abstract: In order to solve the problem of micro grid equipment management confusion, the life cycle management concept applied to the management of micro grid equipment. The equipment management is divided into pre management, mid term management and later management, to achieve the equipment throughout the life cycle of scientific management. At the same time, through the establishment of the equipment management database, the initial information of the micro grid equipment is recorded, and the real time status data of the micro grid equipment at each stage is monitored. The monitoring data and the existing data of the database are analyzed to construct the fault early warning of the micro grid equipment model, determine whether the equipment is normal, timely processing the equipment which needs repair or maintenance. On the other hand, the monitoring data can help analyze the micro grid power generation efficiency， achieve real time monitoring and effective management of micro grid equipment. The results indicate that the micro grid equipment management system improve the reliability of micro grid operation.
