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 changing trend of the line loss rate, it can be seen that the power 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 16...

Abstract

The invention discloses a running abnormality detecting method of a metering device. The running situation of the metering device is comprehensively judged according to analyzing on the variation tendency of a line loss curve, the power consumption information of a user, the meter voltage of the user, the current and other data. According to the method, the running state and the user power consumption condition can be monitored in real time, and the electric energy metering device running abnormality and suspected users with power consumption abnormality can be accurately determined. Meanwhile, the method is more efficient and reliable, and running is easy.

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.
