Embodiment Construction

[0086] Below in conjunction with accompanying drawing and by specific embodiment the present invention is described in further detail, following embodiment is descriptive only, is not limiting, can not limit protection scope of the present invention with this.

[0087] The present invention analyzes the electricity consumption data of a large number of users based on the collection of low-voltage station areas, so it needs to be analyzed through big data processing technology, and the processing of big data is usually carried out by means of a cloud computing platform. Cloud computing, which originated from computers, combines a large number of ordinary computers into a network system similar to supercomputers. The system is meshed into a cloud, which can meet the processing needs of massive big data. Facing the electricity consumption data of a large number of users collected by the terminal-smart meters in the station area, not all the electricity consumption data can be coll...

Abstract

The invention relates to a method for extracting characteristic parameters of a low-voltage area network. The method comprises the following steps: S1, establishing an area network characteristic index system; S2, adopting an association rule mining algorithm-Apriori to realize selection of characteristic parameters of the low-voltage power distribution area; S3, clustering the sample data by adopting an improved K-Means algorithm according to the selected characteristic parameters of the low-voltage power distribution area; and S4, extracting line parameters of the power distribution line byadopting a compact 2D FDFD algorithm. By extracting circuit parameters in the power distribution line, the line loss rate of the system can be reduced by optimizing load power supply, the economic loss is reduced, and the energy conservation and emission reduction work is deeply promoted.

Description

technical field [0001] The invention belongs to the field of electric power metering, and relates to electricity data mining and characteristic parameter extraction technology, in particular to a method for extracting characteristic parameters of a low-voltage station area. Background technique [0002] The line loss rate is an important technical and economic index of the power system, and it is also a comprehensive technical and economic index to measure the operation level and management level of the power enterprise. Efforts to reduce the power loss of the power grid, minimize the management line loss, and control the technical line loss within a reasonable range are an indispensable work for power supply enterprises at all levels. [0003] The low-voltage station area is an important part of electricity consumption. The low-voltage electricity consumption by residents is large and widely distributed, and the structure of the distribution network is complex. Big data ana...
