Description

Technical Field
The present disclosure relates to the field of power metering, and in particular, to a method and an apparatus for identifying a distribution room based on a voltage regulating pattern, a storage medium, and an electronic device.
Background
The domestic power distribution network is managed and operated and maintained by taking a distribution area as a basic unit, and comprises line loss calculation, electricity stealing monitoring and the like, wherein the distribution area refers to a power supply coverage area of a distribution transformer, an intelligent electric meter is used as a core device for electric quantity measurement and electricity consumption parameter monitoring in a power grid, and the membership relation between the intelligent electric meter and the transformer is a very concerned engineering problem of an electricity consumption management department. When the electric meter is initially installed, the platform area relationship of the electric meter is generally clear, but in the subsequent operation and maintenance process, although a power grid company has made a strict flow to prompt relevant personnel to enter a system for recording after operation, and the personnel can be regularly organized for troubleshooting, the coverage area of a power distribution network system is too wide, new operation is continuously performed every day, including installation, capacity expansion, cutting, migration and the like of electric power facilities, and the conditions can cause disorder and even errors of platform area files of a large number of electric meters.
The portable platform area identifier is a common device in the operation and maintenance process of a power grid, and the process is that one party transmits a special signal transmitted along a wire on a line of a known platform area by using a handheld device, and the other party receives the signal on a power supply line of a device to be identified in the platform area, if the signal is correctly received, the transmitter and the receiver are on the same line, otherwise, the signal is not received. The method needs at least two persons with abundant experience and familiar environment to go to the field for live operation, and only can identify the transformer area of a single device each time, thereby being time-consuming, labor-consuming and high in cost. With the wide application of the broadband carrier communication technology in the power utilization information acquisition system, the transformer power supply domain and the power line carrier communication domain are naturally linked, so that the station area identification technology based on the broadband carrier communication process is rapidly developing. However, due to the influence of various factors such as signal crosstalk caused by back-to-back transformer areas and common zero lines, cross-phase transmission of carrier signals, convergence of power supply parameters of power distribution networks of adjacent transformer areas caused by the same high-voltage side, adoption of a non-carrier communication technology in a domestic part of power utilization information acquisition systems and the like, the related technologies still have more problems in actual transformer area testing and application, and a set of specific engineering guide standards cannot be made for transformer area identification by national grid companies and south grid companies by the time of 2021. Some researchers provide a platform area recognition mechanism based on big data analysis or neural network analysis of power consumption parameters, although the platform area recognition mechanism is not limited by a communication mode of a power consumption information acquisition system, the algorithm complexity is high, a large amount of data needs to be collected and calculated and analyzed, hardware and software need to be improved and modified on the existing system, the number of platform areas in China is huge, the power consumption environment is very complex and diverse, and the application range of related algorithms has certain limitation.
