Benefits of technology

This patented system uses two methods - one involves acquiring data about individual devices connected through an electrical circuit or wires that are part of another device called a distributor. Based on this acquired data, it creates models where multiple devices have their own unique characteristics such as power consumption levels and voltage level. These models help identify which parts of these devices may require maintenance more frequently than others. By analyzing these patterns overall, they provide technical means for managing complex networks with diverse components like sensors attached thereto.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the organization and maintenance efficiency of electrical networks used at home or businesses through automated identifications that help identify any issues quickly during troubleshooting efforts without disruptive impacts upon their customers' needs.

Abstract

The invention provides a branch topology construction method and device applied to a power distribution network, and belongs to the technical field of electric powers. The branch topology construction method applied to the power distribution network comprises the following steps: respectively transmitting a current triggering instruction to each node in a transformer area at different time points, so as to trigger each node to transmit a specific current to a respective father node, wherein the specific current is a predetermined and recognizable current; obtaining current statistical information, wherein the current statistical information comprises the number of specific currents received by each node in the transformer area and the receiving time of the corresponding specific currents; and based on the current statistical information and the time point of sending the current trigger instruction to each node, determining the topological relation between the nodes. and constructing the branch topology of a transformer area. Automatic identification and construction of the branch topology in the transformer area are realized.
