Embodiment Construction

[0024] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0025] Please refer to figure 1 , a schematic flow chart of a method for repairing missing voltage data of a smart meter user provided by the present invention, the method includes the following steps:

[0026] In step A, the user voltage data of a station area is obtained based on the electricity consumption information collection system, which is the voltage data at 24 o'clock in a day, that is, the voltage data recorded once every hour. Collected the user voltage data of 20 key users in a station area from September 28, 2017 to January 8, 2018, a total of 110 days, and the voltage data of user C1 on September 28 is shown in the following table:

[0027] Table 1 Voltage value of user C1 on September 28, 2017

Abstract

The present invention provides an intelligent electric meter user missing voltage data restoration method. The method comprises the steps of: obtaining user voltage data of a zone area based on a power utilization information collection system; calculating an average value of voltage difference values of users at corresponding moment; according to the size of the average value of the user voltagedifferences, providing user grouping basis, and performing grouping of the users; and according to a grouping result, providing a user missing voltage correction method, and correcting user missing voltage data between groups. The intelligent electric meter user missing voltage data restoration method can achieve restoration of intelligent electric meter user missing voltage data so as to provideimportant data basis for development of related business.

Description

technical field [0001] The invention relates to the technical field of smart meters, in particular to a method for restoring missing voltage data of smart meter users. Background technique [0002] The smart meter is the smart terminal of the smart grid. In addition to the basic electricity consumption measurement function of the traditional electric energy meter, it also has the functions of electricity consumption information storage and user-side control. With the construction of smart grid, smart meters have become very popular. The smart meter will record and upload the user's voltage, power and other information to the electricity consumption information collection system. These data are important basic data for related work. However, when the smart meter is running, due to communication and other reasons, the voltage data will be lost, and the data loss will bring inconvenience to the operation analysis. [0003] Publication No. CN 105514994 A provides a topology tr...
