An asset management method for a substation in accordance with the present invention generates a unique reliability model for each element of the substation by comparing reliability of a reference reliability model for each substation type with a health index of the each element thereof generated based on state data and real-time monitoring data of the each element of the substation and compensating the reference reliability model for the each element of the substation; assessing system reliability index and economic feasibility for each maintenance scenario based on a reference system reliability model for each candidate element subject to maintenance among the elements of the substation; selecting a maintenance scenario as a result of the health index and the unique reliability model for the each element of the substation, the system reliability index, and the economic feasibility and updating the unique reliability model for the each element of the substation by executing maintenance.

Method for asset management of substation

An asset management method for power equipment in accordance with the present invention comprises steps of generating integrity 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 integrity by the each sub-device; 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 an estimate 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 a predetermined priority and according to execution of maintenance.

Asset management method for power equipment

An asset management method for a substation includes deriving an optimal management plan by each element of the substation depending on integrity of the each element of the substation and deriving an optimal unique reliability model for each element of the substation through a process of compensating a reference reliability model of each substation type and an apparatus executing the method.

Asset management method for substation

Provided is a partial discharge detection device for a transformer, and a transformer using the same. An on-load tap changer is provided on one side of the outer casing of a transformer, and is partitioned from the inside of the outer casing by a shielding wall. A drain pipe is formed on one side of the outer surface of the outer casing. A drain valve is installed in the drain pipe. A configuration for detecting a partial discharge signal generated within the transformer is installed in the drain pipe. That is, a detector body is installed within the drain pipe and the drain valve. A connection mounting member is installed in an end portion of the drain valve. The detector body penetrates the connection mounting member. In the meantime, a portion, such as the on-load tap changer, is partitioned from the internal space of the outer casing by the shielding wall.
