Method for quickly distinguishing transformer area user-transformer relationship

Abstract

The invention belongs to the technical field of power supply management, in particular to a method for quickly distinguishing transformer area user-transformer relations. The line loss electric quantity and the user electric quantity are analyzed by using a Pearson correlation coefficient method; particularly, correlation analysis is carried out on a negative loss transformer area, abnormal userscan be quickly found, the number of field check users is reduced, a user marking unit is designated as a unit, the unit is a meter box (generally one meter box represents the same power supply point,namely the same transformer area), the daily power consumption of the meter box is calculated according to the relationship between the meter box and the users, and then the transformer area relationship of the user meter box is checked; a 'genetic algorithm' is adopted to solve a 'combination problem', one population has a plurality of individuals, and each individual has a chromosome and a corresponding gene and is similar to a knapsack problem in the genetic algorithm.

Description

Technical field: [0001] The technical field of power supply management of the present invention is specifically a method for quickly distinguishing the relationship between stations, districts and households. Background technique: [0002] In the process of transmission, transformation and distribution until the user uses electricity, the line loss in the low-voltage station area has always been an important part of power consumption. The management of the line loss in the low-voltage station area has always been an important basis for the management level and operation level of power supply enterprises. The management work is mostly on-site search for each household, which is time-consuming, inefficient, and inconsistent with the current increasingly strict management of line loss indicators. The change of electrical characteristics can lock the problem users in advance, which can greatly reduce the scope of on-site inspection and improve work efficiency. After analysis, t...

The management of the line loss in the low-voltage station area has always been an important basis for the management level and operation level of power supply enterprises.

After analysis, the number of station districts with file errors, that is, the number of station districts with wrong ownership and division by users, accounted for the largest number, among which the abnormally high loss of archives accounted for more than 60% of the total number of stations, and the negative loss station accounted for about 90% of the total number of stations. % or more, and the current general method for checking the archives of the station area is to check the relationship between households one by one through the line loss detector in the station area. It usually takes a whole morning to check a station area with 500 users, which is extremely expensive. consumption of manpower and material resources
