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 transformer area household transformation relation.
Background
With the advance of the fine management work of the national power grid, higher requirements are provided for the fine management work of a low-voltage distribution room at the tail end of the power supply at present. On the basis of meeting the main assessment target of acquisition success rate, the line loss statistics assessment requirements based on the electricity sales and electricity consumption are higher and higher, the line loss statistics accuracy is ensured to become the work key point of operation and maintenance teams, and the accurate establishment of the transformer area house-to-house relationship is the key and the basis for ensuring the transformer area line loss calculation accuracy. The diagnosis information provided by the adoption system is not comprehensive enough, so that operation and maintenance personnel are required to check the conditions of each transformer area one by one, and the workload is huge, so that the manual checking is urgently required to be replaced by a technical means. In addition, users and distribution line adjustment are modified by adding or deleting in the distribution area, and the situation that operation and maintenance personnel file maintenance errors are inconsistent occurs occasionally, so that the household variation relation is accurately identified, and the method is also an important ring for ensuring the qualified line loss.
The station transformer is not subjected to uninterrupted power verification and real differentiation by a special means for an urban and rural junction with complex wiring and a cable cell, the real relation cannot be accurately reflected according to a construction drawing, and the problem of cross-station copying caused by signal coupling of adjacent station areas cannot be effectively solved by the existing communication technology. Therefore, an efficient platform area household transformation relation automatic identification technology is needed to solve the problem that the platform area line loss rate does not reach the standard due to the error of the ammeter files.
The method for realizing the station area user-to-user relationship identification in the power industry mainly comprises two methods, wherein the first method is to distinguish in a manual power failure mode. And powering off the transformer of the transformer area, and then performing patrol and verification on each line to determine the transformer relationship of the transformer area. The second mode is that the station area automatic identification mode is adopted, the wave generator is installed, the power generator sends power data such as station area numbers, phase sequences, voltages, currents and the like in preset time, and the station area user variation relation is determined. The first mode is a manual power failure mode. The method is direct and accurate, but the notification is issued several days before the power failure, and a large amount of manpower and material resources are called, so that the efficiency is low, the method is inconvenient, the debugging period is prolonged, the working progress is influenced, and the power failure time is too long and is easy to complain by users. The second way is through the platform district automatic identification way. The platform area distinguishing instrument has high 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
