Applied Research Of Reliability-Centered Maintenance Policy Of Substation Equipments

Substation is an important part of the grid. In order to improve the level of power grid reliability, power supply side pays attention to problem about maintenance problem of Substation equipment. Firstly, this paper explains the research and application of RCM at home and abroad and analysis the implementation process of the RCM in detail. In depth understanding of the basis of RCM implementation process, the paper gives the substation equipment fault diagnosis and maintenance decision model approach. Finally, set the transformer as an example, through the using of fuzzy comprehensive method to judge the practical operation'of the 220kV transformer and get the best way of maintenance.
