Description
Technical Field
The invention belongs to the technical field of power systems, and particularly relates to a method and a device for automatically identifying a substation user change relation.
Background
Along with the promotion of the fine management work of the national power grid, higher requirements are currently put forward on the fine management work of the low-voltage transformer area at the power supply end. On the basis of meeting the acquisition success rate as a main assessment target, line loss statistics assessment requirements based on electricity sales and electricity consumption are higher and higher, the accuracy of line loss statistics is ensured to be the working focus of an operation and maintenance team, and the accurate establishment of a residential transformer relation of a platform is the key and basis for ensuring the accuracy of the line loss calculation of the platform. The diagnosis information provided by the mining system is not comprehensive enough, so that operation and maintenance personnel are required to check the conditions of each area one by one, the workload is huge, and the manual check is urgently required to be replaced by technical means. In addition, the conditions of adding and deleting modification users and distribution line adjustment in the transformer area and inconsistent file maintenance errors of operation and maintenance personnel also occur sometimes, so that the user change relation is accurately identified, and the method is an important ring for ensuring the qualification of line loss.
The urban and rural combined part with complex butt lines and the ground cable cell do not have special means to carry out uninterrupted power verification and distinction on the transformer substation, the real relation cannot be accurately reflected according to the construction diagram, and the problem of cross-transformer-area reading caused by signal coupling of adjacent transformer areas cannot be effectively solved by the existing communication technology. Therefore, a high-efficiency automatic identification technology for the transformer relation of the transformer area is needed to solve the problem that the transformer area line loss rate does not reach the standard caused by the error of the electric meter file.
The method for realizing the identification of the household change relation of the station area in the power industry is mainly divided into two modes, wherein the first mode is a mode of manual power failure. And powering off the transformer of the transformer area, and then inspecting and verifying each line to determine the transformer area user change relation. The second mode is to determine the household change relation of the station area by means of automatic station area identification, installing a carrier generator, and transmitting the station area number and power data such as phase sequence, voltage, current and the like at preset time through the carrier generator. The first mode is a mode of manual power failure. The method is direct and accurate, but the notification is issued a few days before the power failure, and a large amount of manpower and material resources are called at the same time, so that the efficiency is low, the inconvenience is brought, the debugging period is increased, the working progress is influenced, and the power failure time is overlong and is easy to complain by users. The second mode is an automatic identification mode through a station area. The station area distinguishing instrument has higher cost, needs to be installed and debugged, needs to distinguish each ammeter or terminal, has large workload, high cost and complex condition, and is easy to generate
Error in error
In view of the above, it is necessary to provide a method and a device for automatically identifying a change relation of a station area with reasonable design and effective solution to the above problem.
