【Title】RESEARCH AND APPLICATION OF "REPLACEABLE MAINTENANCE" TECHNOLOGY SYSTEM IN SMART SUBSTATION
【Abstract】In recent years, smart substation relevant expertise has made considerable progress. Large number of new equipments such as electronic transformer, merge unit, smart terminals and other smart protection devices have been used widely. But, the application of new technologies and equipments has brought many new problems to maintenance work of secondary specialty . It is difficult to get work ticket because secondary circuit in traditional substation is expressed by the network data stream and the maintenance mechanism is not as obvious as usual. Also, since the long time maintenance work of field installation of secondary equipment in smart substation is not allowed and the differences between the intelligence of equipments in smart substation and the process of tranditional safety measures of maintenance work, there are some blind spots in maintenance work of smart substation which are dangerious to persons, equipments and grid. In this paper, we offer a technology system based on "replaceable maintenance", which can reduce the risk of site maintenance operations effectively, improve the efficiency of maintenance operations and provide reliable support for the safe and stable operation of the grid.
