Abstract: In the main network discipline of the power system, currently, each substation is equipped with a separate set of safety tools, which has problems such as large configuration scale, scattered storage, great management difficulty, prominent imbalance in configuration, and low level of information system application. Through an intensive tool management method, solve the problems in decentralized tool management, reduce the total number of tools, reduce the frequency of personnel arriving at the station, and achieve lean management of tools.
