Method and device for identifying relationship between transformer area phase sequence and line households

Abstract

The invention relates to a method for identifying a relationship between a transformer area phase sequence and line households. The method comprises the steps of: acquiring an active current value ofa low-voltage outlet line of each phase of the target transformer area, an active current value data and voltage time sequence data of each electric meter, and voltage time sequence data of a three-phase bus at a distribution transformer low-voltage side; classifying types of the electric meters according to the voltage time sequence data, and acquiring electric meter sets; determining the electric meter set to which the low-voltage outlet line of each phase is to be assigned according to the active current value of the low-voltage outlet line of each phase, the active current values and the voltage time sequence data of the electric meters, the voltage time sequence data of the three-phase bus at the distribution transformer low-voltage side and the electric meter set; and combining arbitrary electric meter sets in electric meter sets of each type, and matching the combined electric meter set to be an electric meter classification set Gamma of a phase low-voltage outgoing line i if asum of the active current values after combination and an active current value of the phase low-voltage outgoing line i satisfy a first preset condition. The method and the device have the advantagesof low identification difficulty, high precision, no need of additionally arranging other terminal equipment, high operability and small operation and maintenance pressure.

Description

technical field [0001] The present invention relates to the technical field of electric low-voltage distribution network, and in particular to a method for identifying the relationship between phase sequence and line households in a station area, a device for identifying the relationship between phase sequence and line households in a station area, computer equipment, and a computer-readable storage medium. Background technique [0002] The traditional low-voltage operation and maintenance management mode lacks the support of the topological relationship of the station area, which can easily lead to problems such as untimely notification of power outages, untimely emergency repairs, long or unresolved low voltage solutions, frequent changes in the station area, abnormal line loss in the station area, etc. , resulting in low customer satisfaction indicators. For this reason, it is particularly important to study the identification technology of the "line-phase-household" rela...
