Embodiment 1

[0025] refer to figure 1 , which is the first embodiment of the present invention, provides a fault detection method for a smart meter based on data detection, and the fault detection method for a smart meter based on data detection includes the following steps:

[0026] (1) Obtain the voltage data change curve of each smart meter in the set area within the set time;

[0027] (2) Obtain the current data change curve of each smart meter in the set area within the set time;

[0028] (3) calculate the voltage mean value curve of the voltage data change curve obtained in step (1) and the current mean value curve of the current data change curve obtained in step (2);

[0029] (4) Compare the voltage average curve and current average curve obtained in step (3) with the set value, and judge whether it exceeds the set value. If it exceeds the set value, it is judged as a smart meter in the set area. There is an exception.

[0030] At least six smart meters are arranged evenly in th...

Embodiment 2

[0033] refer to figure 1 , is the second embodiment of the present invention, this embodiment is different from the first embodiment in that: the controller is connected with an alarm, when the controller determines that the smart meter in the set area is abnormal, the controller drives to start the alarm alarm, alarm.

Abstract

The invention discloses a fault detection method of an intelligent electric meter based on data detection. The fault detection method of the intelligent electric meter based on data detection comprises the following steps: acquiring a voltage data change curve of each intelligent electric meter in a set area within set time; obtaining a current data change curve of each intelligent electric meter in a set area within a set time; calculating a voltage average value curve of the obtained voltage data change curve and a current average value curve of the obtained current data change curve; and comparing the obtained voltage average value curve and the obtained current average value curve with set values, judging whether the obtained voltage average value curve and the obtained current average value curve exceed the set values, and if the obtained voltage average value curve and the obtained current average value curve exceed the set values, judging that the intelligent electric meters in the set area are abnormal. According to the invention, the voltage value and the current value of each intelligent electric meter in a set area are monitored, so that problems existing in a set area can be obtained in time so as to handle the problems in time and feedback sensitively; and voltage and current are detected at the same time, so that fault detection is more guaranteed.

Description

technical field [0001] The invention relates to the technical field of faults of smart meters, in particular to a method for detecting faults of smart meters based on data detection. Background technique [0002] The smart meter is the smart terminal of the smart grid. In addition to the basic electricity metering function of the traditional electricity meter, the smart meter also has the functions of electricity consumption information storage and two-way multi-rate metering in order to adapt to the use of smart grids and new energy. , User terminal control function, two-way data communication function of various data transmission modes. With the development of intelligent power system, the use of smart meters is also increasing on a large scale. In order to timely feedback and process the maintenance of smart meters, the main power station needs to collect the operation data of each smart meter. Analyze the data, evaluate the running status of the smart meter, and determi...
