Embodiment 1

[0024] For users and units participating in the market, as of 12:00 on T+2 days, the metering system still cannot collect their meter data, then the electricity quantity obtained by the time-sharing missing table code fitting method of the metering automation system of the metering automation system in this embodiment is simulated Combined data is used for market settlement. The fitting rules include division rules by time attributes, which are tentatively divided into three types: working days, weekends, national statutory holidays (holidays are divided into small long holidays (New Year's Day, May 1st, Qingming, etc.) and large long holidays (Spring Festival, National Day ) two types); the time period within each day is defined as (0:00-23:00), that is, the data at 24:00 on the 1st of a certain month is defined as the data on the 2nd of the month.

[0025] Specifically, such as figure 1 As shown, the time-sharing missing meter code fitting method of the metering automation ...

Embodiment 2

[0036] This embodiment is similar to Embodiment 1, the difference is that this embodiment uses the electric meter in Embodiment 1 as the main meter, and besides the main meter, it also has a sub-meter so that when the main meter data is missing, the sub-meter collected data as a supplement. Specifically, when the data collected by the main table is missing, first perform the following steps:

[0037] Check whether the auxiliary meter successfully collects the electricity data in the corresponding missing time period. If yes, the electricity data in the missing time period is approximately fitted by the data collected by the auxiliary meter; otherwise, execute step S1 in the first embodiment. In this embodiment, the collected data of the sub-meter is used as backup data. When the sub-meter is working normally, the data of the sub-meter can be used directly. When the sub-meter and the main meter fail at the same time, data fitting is performed by the method in the first embodime...

Abstract

The invention provides a time-sharing missing meter code fitting method for an electric meter of a metering automation system, and the method comprises the following steps: S1, taking an interval electric quantity arithmetic mean value of time points before and after an interval of a missing time period as an electric quantity fitting value when the time length of the missing time period is smaller than a first preset time length; and S2, when the time length of the missing time period is greater than the first preset time length, taking the electric quantity / meter code data of the electric meter in the same attribute date for approximate fitting. According to the invention, different processing is carried out according to the length of the missing time period, the missing data is respectively processed according to the time attribute under the condition that the missing time period is long, the power consumption habit of a user is met, the missing data in various time periods can be more finely processed, and the deviation between a fitting result and a real result is reduced as much as possible.

Description

technical field [0001] The invention belongs to the technical field of electric energy data processing in electric power systems, and in particular relates to a method for fitting time-sharing missing table codes of electric meters in a metering automation system. Background technique [0002] The problem of missing electric energy data can be formalized as the problem of automatic interpolation of missing data. For the problem of missing electric energy data, due to the difference in the environment of the measurement point, the data distribution may be completely different, and there may be a very large gap between the result obtained by applying the same set of parameters and the real value. Therefore, researching a processing method that automatically performs interpolation according to the data distribution has become a problem to be solved in the online processing of electric energy data. [0003] In order to solve the above technical problems, people have carried out...
