Embodiment 1

[0060] Such as Figure 1-2 As shown, the power data quality assessment method and its device provided by the present invention were used to analyze the data quality of power consumption information collected by a power company in a certain city in March 2015. The analysis work included overall normative analysis, file data quality Analysis, curve data quality analysis and historical data quality analysis are carried out in four aspects. The specific analysis is as follows (the data quality evaluation process of the criterion layer is Figure 5 ).

[0061] analysis object

[0062] The analysis is aimed at collecting detailed data of electricity consumption information in a certain city in 2015, and the specific analysis objects are shown in Table 1.

[0064]

[0065] This data quality analysis is based on Hadoop's big data analysis platform, making full use of HDFS distributed storage, Hive databas...

Embodiment 2

[0072] Such as image 3 As shown, the evaluation and verification of the basic layer data evaluation index system includes three levels: verification of time series data based on grid operation attribute values; data verification based on multiple data sources of power grid operation; correlation relationship between power grid operation data verification;

[0073] The verification level of time series data based on grid operation attribute values ​​includes;

[0074] Threshold discrimination by time interval setting: Divide the regular data set into intervals of different intervals, set the maximum threshold and minimum threshold respectively with reference to their fluctuation ranges, and determine each data within the intervals of the maximum threshold and minimum threshold as meeting the interval threshold evaluation rules.

[0075] Data horizontal comparison: compare the data at a certain time with the data at the time before and after it, and if the difference is greate...

Abstract

The invention discloses an electric power data quality evaluation method and device. The method specifically comprises the steps of selecting a base layer data evaluation index and a criterion layer data evaluation index according to a to-be-evaluated data object, matching the basic layer data evaluation index and the criterion layer data evaluation index with a corresponding data evaluation ruleset, and endowing each criterion layer data evaluation index with a weight value W and an expected value E, extracting a to-be-evaluated data object and performing data preprocessing on the to-be-evaluated data object to obtain first processing data, performing base layer evaluation verification on the first processing data according to a base layer data evaluation index to obtain a first verification result, performing criterion layer evaluation verification on the first processing data according to a criterion layer data evaluation index to obtain a second verification result, and calculating a data quality comprehensive evaluation result according to the first verification result and the second verification result. The evaluation verification process reflects the quality level of the data resources with a plurality of quality dimension measurements to more accurately evaluate the quality of the data.

Description

technical field [0001] The invention relates to the technical field of power big data evaluation, in particular to a power data quality evaluation method and a device thereof. Background technique [0002] With the continuous construction and deepening of the application of informatization in power supply enterprises, various businesses of power supply enterprises have been initially integrated with informatization, and the number and types of business data in the information system have gradually increased, and the demand for data sharing is urgent. However, the data quality and the level of data sharing and utilization are not high. First, the data support for analysis and decision-making is low. The same data has multiple sources and inconsistent statistical standards. Second, the data support for operation management needs to be improved, and the data quality varies. Part of the data has no business system support, and lacks unified norms, standards, and clear data accou...
