Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Taking the voltage fluctuation data of the medium-voltage feeder under the fault state as an example, this is a typical power quality problem, and its data type belongs to event data. The specific flow chart of the power data quality evaluation and rule verification method in the embodiment of the present invention is as follows figure 1 shown, including:

[0026] Step S1: Build a power data quality assessment system and a data rule verification database;

[0027] (1) Firstly, build a complete power data quality evaluation system, aiming at data types, data attributes, data representation forms, data exchange specifications, and data sharing processes, etc., to form a comprehensive set of differentiated data such as basic data, operating data, and event data. The comprehensive evaluation index sys...

Abstract

The invention discloses a method suitable for power data quality assessment and rule check. The method comprises the steps of establishing a differential data quality comprehensive evaluation index system and a data quality rule check library for a device object of a specific region in a power system and for data describing a basic feature, a running feature and an event process of a power device; and automatically generating a multilevel data check rule set based on the rule check library according to to-be-checked power data, thereby realizing automated data monitoring and check. According to the method, the power data quality comprehensive evaluation index system and the data quality rule check library are established and the multilevel power data rule set is automatically generated, so that the features of differential power data are comprehensively assessed and comprehensively evaluated; and the method is of important significance for realizing data quality management control and forming a technical scheme and a long-term mechanism of data management.

Description

technical field [0001] The invention relates to a method suitable for electric power data quality evaluation and rule verification, which belongs to the technical field of electric power data management. Background technique [0002] With the large-scale access of clean energy and electric vehicles, the physical structure and operating characteristics of the power system have undergone fundamental changes. The data representing power system equipment, operation, and calculations are more abundant, and the data dimensions are getting higher and higher. And the sources are more diverse, and the factors that affect data transmission and accuracy are more difficult to determine. At present, the processing capacity of the existing data quality verification system based on traditional database systems and computing platforms has serious bottlenecks, making it difficult to quickly complete data quality monitoring and verification. On the other hand, the characteristics of real-tim...
