Method for identifying user-transformer relationship in low-voltage transformer area

Abstract

The invention provides a method for identifying a user-transformer relationship in a low-voltage transformer area, which solves the problems of unreliable identification result, low identification efficiency and large potential safety hazard of the existing method for identifying the user-transformer relationship in the low-voltage transformer area. The identification method provided by the invention comprises the following steps of: firstly, dividing all distribution transformers in a transformer area to be identified into a plurality of sets; performing diversity identification; then, sequentially confirming the correlation between the user and the voltage effective value of the distribution transformer, the correlation between the user and the voltage effective value of other users confirmed to be hung on the distribution transformer and the correlation between the user and the voltage effective values of other distribution transformers in the transformer area recorded in the transformer area file, so as to confirm and identify the user-transformer relationship of the low-voltage transformer area; the invention has the advantages of simple operation, no need of on-site instrument identification equipment, avoiding of the problem of transformer area crossing of present identification methods, overcoming of the defect of unreliable identification results, no need of on-site operation of workers, high identification efficiency, and avoiding of possible safety hidden troubles.

Description

technical field [0001] The invention relates to the technical field of identification of the topology relationship of low-voltage station areas, and more particularly, to a method for identifying the household-change relationship of low-voltage station areas. Background technique [0002] The line loss of the low-voltage station area is an important part of the line loss management. How to effectively calculate the line loss of the low-voltage station area and formulate the corresponding loss reduction strategy is of great value to improve the operating efficiency of the enterprise and the operation efficiency of the power grid. District topological relationship is an important basis for line loss analysis in the same period, and the inaccuracy of station area file information (including station area topological household change relationship) will inevitably lead to abnormal line loss analysis results. However, my country's power industry has long suffered from the drawbacks...
