Recognition method, device and equipment for customer line and household relationship in vacant rooms in Taiwan area

Abstract

The present invention relates to a method, a device and a device for identifying the relationship between vacant subscribers and households in the station area. The method for identifying the relationship between vacant user lines and households in the station area includes: obtaining the voltage time series data and active current time series data of each electric meter in the target station area, as well as the active current time series data at the head end of the low-voltage outgoing line of each phase; The user's electricity meter; determine the voltage correlation of each meter according to the voltage time series data of each meter, cluster the vacant electricity meter and the electricity meter with the greatest correlation, and calculate the total active current of all electricity meters under each category respectively; The time series data of active current at the head end of the low-voltage outlet and the sum of active currents of various categories are used to solve the line-to-household relationship identification optimization model to determine the line-to-household relationship of vacant users. Based on the user voltage characteristics of higher voltage correlation coefficients of users with the same phase line and short electrical distance, the above identification method realizes the accurate identification of the relationship between the vacant user line and the household in the low-voltage station area.

Description

technical field [0001] The invention relates to the technical field of electric power distribution networks, in particular to a method, device and equipment for identifying the relationship between lines and households of vacant users in a station area. Background technique [0002] In rural areas or other remote areas, many users choose to go out to work all year round, and usually only use electricity when they return to their hometowns during holidays. This makes the vacancy rate of such users relatively high. Therefore, users who do not usually use electricity are called vacant users. The vacant users account for a large proportion of the peak load of electricity consumption during holidays, and the lack of line-to-household relationship of vacant users seriously restricts the optimal management of electricity consumption during peak load in the low-voltage station area. The identification method is particularly important. [0003] The current identification methods of ...
