The application of the data warehouse and data mining technology in electricpower system has become one of the most prevalent topics at present. The optimaloperation and safety operation of steam turbine have been the most focused. On thebasis of many materials related to the data warehouse ,data mining and steamturbine technology both domestic and international, the current information state ofin electric power enterprise is analysed, and on the basis of deep analysis for DCSsystem, data warehouse and data mining focused on the analysis and prediction ofturbine performance is designed. The result can provide that data mining and datawarehouse technology can be used to improve science and reliable evidence foreconomic operation and safe operation of the turbine units. It has high practicalvalue.
