Abstract

The invention provides a data storage method and device facing a power utilization load classification application. The method comprises that a wavelet primary function is selected to carry out multi-resolution decomposition is carried out on preprocessed power utilization load data to obtain a candidate characteristic wavelet coefficient set, and label information is added to the preprocessed power utilization load data; a characteristic wavelet coefficient is selected from the candidate characteristic wavelet coefficient set, and a power utilization load data characteristic model is established; the power utilization load data characteristic model is used to carry out characterization on the power utilization load data; and user charge data after characterization is stored. Advantages ofthe wavelet transformation is applied to characteristic extraction of the power utilization load data, the data is stored in a compressed way, original information is maintained, and support is provided for subsequent applications as power utilization load classification; and the quantity of characteristic wavelet coefficients is adjusted, the optimal and fewest characteristic wavelet coefficientis selected, and the characterization efficiency of the power utilization load data is improved.

Description

technical field [0001] The invention relates to a data characterization technology, in particular to a data storage method and device for application of electric load classification. Background technique [0002] With the advent of the era of big data, organizations and enterprises from all walks of life regard data as an important resource for future development, and invest heavily in the research and development of data collection, transmission and storage technologies. For power grid enterprises, the large amount of data, various types, and high value have become the basic elements to promote the development of companies and society. [0003] Electricity load data are all numerical records, but the amount of data records is large, the records are intensive, the data redundancy is large, and the storage space is high. Its handling, storage, analysis and processing require large-capacity storage and high-performance computing platform support. Therefore, it is necessary to...
