Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as figure 1 As shown, this embodiment discloses a method for judging the abnormality of the time-sharing meter code of the meter automation system, including:

[0047] A. When the meter code of the electric energy meter increases abnormally, it is judged that there is an abnormal problem of the electric energy meter flying away;

[0048] B. When the meter code value of the electric energy meter at the last time point is less than the meter code value of the electric energy meter at the previous time point, it is judged that the electric energy meter has an abnormal problem of the meter code going backwards;

[0049] C. When the code of the electric energy meter does not change, but it is running under load, it is judged that the electric energy meter has an abnormal problem of the meter code stopping.

[0050] Specifical...

Abstract

The invention provides a metering automation system ammeter time-sharing meter code abnormity determination and restoration method comprising the following steps: A, when the ammeter code of an electric energy meter is abnormally increased, determining that the electric energy meter has an electric energy meter flying abnormity problem; B, when the meter code value at the next time point of the electric energy meter is smaller than the meter code value at the previous time point of the electric energy meter, judging that the electric energy meter has a meter code backward abnormal problem; andC, when the meter code reading of the electric energy meter is not changed but load operation exists, judging that the meter code of the electric energy meter is stopped abnormally. Three abnormal conditions of electric energy meter flying away, meter code reversing and meter code stopping can be judged, and meter code abnormity of various conditions can be effectively and accurately judged.

Description

technical field [0001] The invention belongs to the technical field of power system electric energy data processing, and in particular relates to a method for judging and repairing the abnormality of the time-sharing meter code of the electric meter in the metering automation system. Background technique [0002] There will be data abnormalities in the use of electric energy meters. There are many situations that cause data abnormalities. The existing technology cannot accurately determine whether the data collected by electric energy meters is abnormal, nor can it repair the abnormal data. The data is processed. [0003] In addition, for the problem of missing electric energy data, due to the differences in the environment of the measurement points, the data distribution may be completely different, and there may be a very large gap between the results obtained by applying the same set of parameters and the real value. Therefore, researching a processing method that automa...
