Development Of The Data Mining System Based-on The Data Warehouse Of Power Plant Units

With increasing automatization level of power plant units, DCS system is usedwidely in power plant, they have established data mine which covers with the process ofproduction in power plant. In order to make full use of data mine of data and discoveravailable knowledge containing in the data ,and elevate management of operation inpower plant ,so this paper assumes to exploit the data mining system based on the datawarehouse of operation in power plant, for making full use of the function of the datacollected in DCS system in power plant, which can direct electric power production. Firstly, in this paper, establish data warehouse of operation in power plant , thenassume to exploit the data mining system based on the data warehouse , and use thesystem to analyse performance of units .As a result, get lots of information rules, aftervalidation of practice and experts' evaluation ,use the information rules to direct aprocess of production .The exploitation of the data mining system based on the datawarehouse of operation in power plant, has established a groundwork for informationalcourse of electric power corporation and establishment decision-making backup system .
