Description

technical field [0001] The invention relates to a fast topology identification system for a low-voltage station area, which belongs to the technical fields of smart grid and smart electricity utilization. Background technique [0002] In many old communities and remote areas in China, there are problems such as confusion in the filing of power projects and unclear topology of the station area. At present, due to the lack of accurate line topology diagrams in many low-voltage station areas, it is difficult to quickly and accurately troubleshoot problems when a line fails, and there are problems of low troubleshooting efficiency, long cycle time, and high cost. A lot of manpower, material resources, and financial resources were wasted, and the final problem could not be effectively solved. To solve this problem, the common practice under the current technology is to rely on the power supply department to provide the topology data of the station area saved during the construct...

Problems solved by technology

However, due to the large number of distribution stations of the power company and the complexity of electrical wiring, there is still a phenomenon of private construction and random construction. Especially in some old residential areas and remote areas, due to various load adjustments that have not been filed and adjusted in time and listing errors, etc., the power supply department Obtaining the original topological relationship information during the construction of the station area is usually incomplete and unreliable

[0003] There are three main reasons for the wrong topological relationship of the low-voltage station area: (1) errors in the files of the electric meter of the user during the construction of the low-voltage station area, resulting in an error in the topology of the low-voltage station area; (2) insufficient attention to the station area, and only recording The information of some station areas caused the loss of topological information of some low-voltage station areas; (3) when the low-voltage station area failed, there was no record or wrong record when the wiring was adjusted during the inspection and emergency repair, resulting in the topological error of the low-voltage station area
