A data-driven verification method for household substation relationships in low-voltage station areas

Abstract

The invention discloses a data-driven checking method for the relationship between households in a low-voltage station area, which includes the following steps: (1) Calculate the line loss rate of all station areas in the same residential area according to the settlement and power supply assessment data of the electricity sales side of the station area ;(2) Determine whether the reason for the unqualified line loss rate of the residential area is the wrong household-change relationship; (3) Establish a data-driven household-change relationship verification model; (4) Solve the model and give the household-change relationship in the station area (5) Adjust according to the adjustment scheme in step (4) in the electricity collection system. The present invention is based on user historical data of the station area and power supply data of the distribution transformer in the station area, and uses an optimization algorithm to propose a data-driven household transformer relationship checking method. This method can give suspected users with wrong household-to-change relationships, and can effectively avoid the tedious work of previous household-to-house screening, so that the line loss rate can reach a qualified level.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and relates to a data-driven checking method for household transformer relations in low-voltage station areas. Background technique [0002] The electric energy produced by the power plant in the power system is supplied to the user through the transmission, transformation and power supply links of the power grid. In the process of transmitting and distributing electrical energy, each component in the power grid (such as transformers, transmission lines, compensation and adjustment equipment, and measurement and protection devices, etc.) consumes a certain amount of electrical energy. [0003] A low-voltage station area refers to the power supply range or area of ​​a distribution transformer. The scope of line loss calculation in the low-voltage station area starts from the watt-hour meter installed at the outlet of the 10kV distribution transformer in the station area and ends wi...
