Embodiment Construction

[0065] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0066] The information quality quantification method provided by this application can be applied to such as figure 1 shown in the application environment. The application environment includes a substation 11 and a secondary system 12 of the substation. Among them, the secondary system 12 of the substation communicates with the substation 11 through the network, obtains the data information during the operation of the substation in real time, and stores the data information in the secondary system of the terminal substation. Data information, classify and quantify data in...

Abstract

The invention relates to an information quality quantification method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring data of a substation secondary system in a preset time period; performing clustering analysis on the data by adopting a clustering method based on a shuffled frog leaping algorithm to obtain a plurality of data sets; performing quantitative analysis on each data set according to at least two preset evaluation indexes to obtain data proportion of each data set under each evaluation index; and according to the data proportion of each data set under each evaluation index and the target weight of each evaluation index, obtaining the quality quantized value of each data set. By adopting the method, the accuracy and efficiency of information quality quantification can be improved.

Description

technical field [0001] The present application relates to the technical field of information quality evaluation, in particular to an information quality quantification method, device, equipment and storage medium. Background technique [0002] With the continuous increase in electricity demand in daily life and manufacturing, and the rapid development of power systems, the use of smart substations has become more common, resulting in a continuous increase in the amount of data collected by the secondary system of smart substations. Therefore, when the operation and maintenance personnel of the plant station need to maintain the data information of the smart substation, they need to use valuable data information as the judgment basis for operation and maintenance, which requires the quality evaluation of the massive data information in the secondary system of the smart substation , to obtain valuable data information. [0003] In the prior art, when evaluating the quality of...
