Electricity consumption condition monitoring method and system for users in low-voltage transformer area

Abstract

The invention discloses a power consumption condition monitoring method and system for users in a low-voltage transformer area, and the method comprises the steps: dividing all users in the transformer area into high-power-consumption users and low-power-consumption users according to the historical daily average power consumption of the users, and carrying out the power consumption monitoring for the users with different power consumption; further identifying the electricity larceny suspicion of the high-power-consumption user and the low-power-consumption user, determining the historical normal metering data of the electric energy meter through a dynamic time window in identifying the electricity larceny suspicion of the high-power-consumption user, setting a first threshold value requirement, comparing the real-time metering data of the electric energy meter with the first threshold value requirement to identify the electricity larceny suspicion according to a comparison result; in the process of identifying the electricity larceny suspicion of the low-power-consumption user, comparing the electricity larceny suspicion with the real-time metering data of the electric energy meter through a preset second threshold value requirement, so the electricity larceny suspicion is identified according to the comparison result. Based on the scheme, the load scale and the required power consumption scale of the users in the transformer area are fully considered, and the misjudgment rate of electricity larceny is reduced.

Description

technical field [0001] The present application relates to the technical field of power distribution data monitoring, in particular to a method and system for monitoring power consumption of users in a low-voltage station area. Background technique [0002] At present, with the deepening application of energy meter data collection, the requirements for lean management of users' electricity consumption in the station area are constantly increasing. For example: event records such as opening the meter cover of the user meter in the station area, abnormal zero live wire, voltage loss, current loss, phase failure, the latest power outage time, clock out-of-tolerance, voltage loss of the meter clock battery, etc., have not yet been effectively recorded. According to the method, the abnormal power consumption of users in the station area will have a great impact on the line loss. [0003] At present, the traditional technical method is to conduct on-site inspections of users door ...
