Abstract

The invention discloses a method and system for cleaning power transmission and transformation reliability evaluation big data, and the method comprises the steps: clustering of to-be-tested sample data through a hierarchical clustering CURE algorithm, and obtaining a clustering cluster of normal sample data; selecting boundary sample data based on the clustering cluster of the normal sample data;according to an abnormal data identification algorithm based on a boundary sample, identifying abnormal data in the to-be-tested sample data, and identifying the abnormal data; labeling the positionof the identified abnormal data in the to-be-tested sample data; correcting the abnormal data by applying an exponential weighting moving average method according to the marked position of the abnormal data to obtain a correction result of the abnormal data; and replacing abnormal data in the sample data with the correction result.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation reliability evaluation by power grid enterprises, and more specifically, relates to a method and system for cleaning big data of power transmission and transformation reliability evaluation. Background technique [0002] With the release of the "White Paper on the Development of China's Electric Power Big Data", it has led to an upsurge in research on big data for power transmission and transformation reliability assessment in the power industry. Accuracy and reliability are the basic requirements to ensure the accuracy of big data analysis and processing for power transmission and transformation reliability assessment. Therefore, higher requirements are put forward for the quality of big data for power transmission and transformation reliability evaluation. Big data cleaning for power transmission and transformation reliability evaluation can effectively ensure the co...
