Problems solved by technology

Traditionally, the abnormal operation of electric energy metering devices can only be found through the event recording function of electric energy meters and manual on-site inspections. However, these methods are inefficient and cannot monitor the operating status of metering devices in real time. and so on

Embodiment

[0047] Example: In the power consumption information collection system, the historical line loss curve of a station area is found as follows: Figure 9shown. There are 24 non-resident households and 81 residential households under the station area, with a total of 105 single-phase and three-phase metering points. Analyzing the change trend of the line loss rate shows that the electricity sales in this station area decreased suddenly and the line loss increased suddenly on the 6th, 15th and 26th respectively. The main cause of the abnormal line loss is suspected to be the intermittence of the metering device. Fault or abnormal behavior of power consumption. Analyzing the line loss fluctuation between No. 5 and No. 7, there should be obvious sudden changes in power consumption in the station area on December 5 and December 7 respectively. Among them, the sudden increase of power on December 5, On December 7, the power dropped suddenly, and the sudden power was about 160~200k...

Abstract

The invention discloses a method for detecting abnormal operation of a metering device, which comprehensively judges the operation status of the metering device by analyzing the change trend of the line loss curve and combining the user's power consumption information, the user's meter voltage and current and other data. The method provided by the invention can monitor the operation state of the metering device and the power consumption status of users in real time, and accurately lock the abnormal operation of the electric energy metering device and the user who is suspected of abnormal power consumption. At the same time, the method provided by the invention is more efficient, reliable, and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of low-voltage power consumption, and relates to a method for detecting abnormal operation of a metering device. Background technique [0002] Since the operation stability and reliability of electric energy metering devices directly affect the fairness and fairness of electricity trade settlement, and are related to the safe operation of the power grid and the safety of electricity consumption of users, the monitoring of the operating status of electric energy metering devices is particularly important. important. Traditionally, the abnormal operation of electric energy metering devices can only be found through the event recording function of electric energy meters and manual on-site inspections. However, these methods are inefficient and cannot monitor the operating status of metering devices in real time. and so on. Contents of the invention [0003] Object of the invention: The object of the inventi...
