Embodiment 1

[0027] An embodiment of the present invention, its main steps are as figure 1 shown.

[0028] Step 1: Configure the data source. For multi-source data of power grid substations, multi-source data adapters and ETL tools are provided to meet the needs of data quality inspection and analysis for accessing and extracting various types of data sources. Configure parameters such as connection addresses and ports of one or more databases in the source system through ETL tools and JDBC, select a data source driver adapter according to the data source type, connect to the database, perform connectivity verification, and preview data. Databases include relational databases, real-time databases, or HBase databases. Data quality analysis adopts distributed cache, big data processing technology, stream processing such as storm and spark steaming, spark memory parallel computing, kafka distributed message queue, etc., to meet the needs of large-scale measurement data quality identificatio...
