The invention discloses a data quality analysis evaluation model facing electric power big data. Core functions of the data quality analysis evaluation model facing electric power big data comprise steps of performing processing on a collection plan and a restriction rule in a basic model, calling a background storage realizing checking and analysis through a data quality control model, executingchecking and forming a checking result in an entity database, performing analysis, computing, classification and summarization through an analysis program, generating a quantized index result reflecting a plan completion state and data quality, storing the result in an analysis result table, and calling the analysis table through a foreground to generate a data quality analysis evaluation report which reflects various quantized indexes of data quality problems in detail. The invention improves an automated level of data quality analysis and evaluation, realizes intelligent management and control of data quality, satisfies data quality control requirement for big batch data, and realize quantized analysis and evaluation for data integrity, timeliness, accuracy and consistency.
