Meanwhile, the geographical coordinates of the line loss abnormality can be further determined, the analysis level of the power grid data is improved, the judgment result is more accurate, the power consumption abnormality behavior of the transformer area can be rapidly identified for targeted investigation, and the workload is greatly reduced.
In a specific embodiment, step 1 specifically includes:
101. generating a platform area model according to the sequence of the equipment connection relation, the current geographic coordinates of the equipment and the key equipment parameters from the distribution transformer;
102. drawing a geographic edge layout according to the platform region model, and generating a logic single line diagram through the geographic edge layout;
103. scanning two-dimensional code identification table numbers of all the user electric meters, interacting with a marketing system to obtain user names, and obtaining a variable-line-user logic relationship in the platform area based on a logic single line diagram.
The equipment comprises actual equipment and planned equipment.
Specifically, according to the topological connection relation of the distribution transformer equipment, starting from the distribution transformer, according to the sequence of the equipment connection relation, the current geographic coordinates of the equipment and the connection relation of the previous equipment are automatically recorded beside the actual equipment or the equipment to be built, and a small number of key equipment parameters are recorded, so that a platform area model is formed.

Meanwhile, the method does not depend on communication among devices, does not have interference to meter reading processes, can be used for modeling when the devices are planned, and can be used in a planning and designing stage.
In a specific embodiment, step 3 specifically includes:
301. obtaining a branch line structure of a platform region and branch line information of a user according to the platform region model;
302. and generating a station area line loss curve according to the total table of the station area, the load record data of the user electricity meter, the station area branch line structure and the branch line information of the user.

And then, generating a station area line loss curve according to the total table of the station area, the load record data of the user electricity meter, the station area branch line structure and the branch line information of the user. Further, lines, users, areas and line loss curves can be generated, so that precise analysis can be performed.
Calculating the line loss rate of the transformer area at each moment through calculating the total load of the transformer area and the total load of the user electricity meter at different moments, and obtaining a line loss curve of the transformer area after connecting the values of the line loss rate at each moment, wherein in a specific embodiment, the step 4 comprises the following steps:

402. judging the correlation between the line loss curve of the area and the user load curve according to the morphological similarity; if the user is positively correlated, the user has abnormal line loss; if the correlation is negative, the user has electricity stealing behavior.
Specifically, calculating the similarity between the line loss curve of the area and the user load curve by adopting a shortest distance method; judging the correlation between the line loss curve of the area and the user load curve according to the morphological similarity; the line loss curve is positively correlated with the load curve, which indicates that the line condition of the subscriber is not good, such as complex wiring and non-optimal fault; the line loss curve is inversely related to the load curve, then the user is indicated that the user may have electricity stealing behavior, such as intermittent electricity stealing user behavior; and (5) targeted investigation, rapidly finding out and analyzing the users generating line loss.
Also, since the line loss ratio= (source-end load)/source-end load is 100%, when the end load increases, the poor surface line condition causes the line resistance to increase, thereby aggravating the increase of the source-end load, and eventually causing the line loss to increase. A positive correlation indicates that the subscriber line condition is poor. If the line loss increases when the end load decreases, it proves that the external equipment is causing load on the current line, and the user may have electricity stealing behavior.
After the similarity is obtained, the embodiment can also compare the similarity with a historical similarity database, and can find abnormality, so that a user generating line loss can be more quickly searched and processed in a targeted manner.
In a specific embodiment, the method further comprises:

determining a power supply path corresponding to the abnormal voltage moment based on the platform region model, so as to obtain a voltage drop distance curve;
and determining a fault line section according to the pressure drop distance curve and the branch line information of the user.
The total table and the load record data of the user ammeter comprise 24 hours of a day, so that the most serious moment of low voltage of the user can be determined according to the total table and the load record data of the user ammeter, then a voltage drop distance curve is determined according to a power supply path corresponding to a table model at the moment, specifically, for example, the voltage of the ammeter of the user a at the moment t is 100v, the voltage of the total table of the table is 120v, and the power supply path and the line length of the user can be obtained through a single line diagram of the table model. And then a voltage drop distance curve, namely a voltage drop distance curve of the transformer area, can be obtained through line voltage drop calculation, and a main line section causing low voltage can be further determined according to the branch line structure of the transformer area in the transformer area model and the branch line information of a user, so that the investigation is conducted pertinently.
The connection relation between each user and the distribution transformer can be seen from the distribution diagram and the single line diagram of the transformer area, such as the users with serious low voltage and the users with collinear periphery are extracted in a targeted mode, and the main section of the line section is further judged through the line trend.
In a specific embodiment, the method further comprises:
calculating the line loss value of each line section corresponding to the maximum moment of the line loss of the station area, and calculating the corresponding loss density according to the line loss value line and the line length of each line section;
and sorting the line loss density of each line section from large to small, and marking the line section sorted in front of the preset position as a suspected fault section.
Specifically, the invention can determine the maximum moment of the line loss of the transformer area through the line loss curve of the transformer area, then the line loss of each line in the transformer area at the moment can be obtained, and the line length of each line can also be calculated according to the geographic coordinates of the line, thereby calculating the line loss density. And then, the line sections with relatively large line loss are found out, and the investigation is correspondingly performed, for example, the proportion of the line loss to the total line loss of each line section is ordered, and the line section with the front of the line section is used as the main line section, so that the targeted investigation is performed.
