This new management model takes networking as the core, and compares the planning goals in a "bottom-up" manner, dividing the power supply area into several "grids" according to certain standards, and each grid is composed of several "grids". Compared with the traditional management model, the protection and management of power facilities based on the grid model has higher efficiency and better flexibility. It can achieve coverage and precise management of power facilities to a certain extent, but it does not fundamentally solve the drawbacks of low efficiency and inability to implement precise monitoring of power facilities. Therefore, under the new grid management model, it is more urgent to solve the pain points of power maintenance, that is, remote control and automated management of power facilities to improve management efficiency and convenience.
