Embodiment 1

[0044] An intelligent identification method for erecting distribution network lines on the same tower, comprising the following steps:

[0045] S1: Obtain the ledger information of the distribution network line ring network through the power distribution GIS model database, and extract the XML graphic information of the one-line diagram;

[0046] S2: convert the XML graph into a data file according to the S1 line;

[0047] S3: Carry out line topology analysis based on the data files converted by S2;

[0048] S4: Extract the key "station line" and "pole tower" information of the line from the data obtained by the analysis of S3;

[0049] S5: Output the full ledger information of the distribution network line to analyze the line line erected on the same tower;

[0050] S6: Analyze according to the full ledger information of the distribution network lines output by S5, and intelligently identify whether the towers correspond to multiple lines;

[0051] S7: For the subordinate ...

Embodiment 2

[0071] like figure 1 As shown, an intelligent identification method for the erection of distribution network lines on the same tower (pole) needs to automatically extract the power distribution GIS model to automatically extract the distribution network line ledger data method process, which involves the automatic extraction of distribution network line ledger data by the power distribution GIS model method flow. The principle of its working method is as follows:

[0072] Analyze and filter the data by extracting the line diagram model files in the GIS system, extract the one-line diagrams that are still in use, and eliminate all the archived and unpublished one-line diagrams to form an effective GIS diagram model database, and then go according to the topological relationship Analyze the hierarchical relationship between the trunk and branch lines in the feeder to form a line topology relationship table; extract key information from the line affiliation relationship obtained...

Abstract

The invention provides an intelligent identification method for erecting a distribution network line on the same tower. The method comprises: extracting a circuit diagram model file from a GIS systemfor analysis; screening data, extracting a single-line diagram which is still in use at present, removing all single-line diagrams which are archived and are not published to form an effective GIS diagram model database, and analyzing a hierarchical relationship between a main line and branch lines in a feeder line according to a topological relationship to form a line topological relationship table; and performing key information extraction on the line affiliation obtained through topology analysis and the output data file. According to the method, the identification capability of equipment erected on the same tower is presented in a normal operation mode of a distribution network line, and the method has the characteristics of high accuracy, strong effectiveness, high reliability and thelike.

Description

technical field [0001] The invention relates to the field of power grid information technology, and more specifically, to an intelligent identification method for distribution network lines erected on the same tower. Background technique [0002] The distribution network line points are multi-line, long and wide, the path is complex, the quality of the equipment is uneven, and the operating environment is relatively complex. Manual identification based on the single-line diagram will take a lot of work. Therefore, it is necessary to study the intelligent identification of the same tower (pole) to improve efficiency. It is necessary to reduce the workload. [0003] At the same time, the one-line diagram is an indispensable tool for monitoring the operation of the power grid. With the continuous expansion of the power grid scale, the traditional manual identification based on the one-line diagram has a large maintenance workload and is prone to errors. The problem of strong i...
