Low-voltage transformer area household-transformer relationship checking method based on data driving

Abstract

The invention discloses a data driving-based low-voltage transformer area household-transformer relationship checking method, which comprises the following steps of: (1) calculating line loss rates ofall transformer areas in the same residential area according to electricity selling side settlement and power supply assessment data of the transformer areas; (2) judging whether the line loss rate disqualification reason of the residential area is a household-transformer relationship error or not; (3) establishing a household-transformer relationship checking model based on data driving; (4) solving the model, and providing an adjusting scheme of a transformer area household-transformer relation; And (5) carrying out adjustment according to the adjustment scheme in the step (4) in the powerutilization acquisition system. Based on user historical data of a transformer area and distribution transformer power supply data of the transformer area, an optimization algorithm is utilized, and adata driving-based household transformer relation checking method is provided. According to the method, suspected users with wrong household-to-household relationships can be provided, and tedious work of household-by-household screening in the prior art can be effectively avoided, so that the line loss rate reaches 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...
