Design And Implementation Of Data Acquisition System For Custom Energy Consumption Of Liaoning Power Company

Power industry is supporting economic and social development of basic industries and public utilities,with the rapid development of China’s national economy and the improvement of people’s living standards,reliance on electricity is also increasing.With the increased use of electricity each year,is also gradually increasing the size of the grid,involving a broad geographic range,a variety of power facilities,including a transformer substation,transformers,surge arresters,meters,switches and other equipment of a secondary high-voltage equipment and substations radiation the levels of transmission lines and electrical equipment maintenance capture information area on electricity is becoming increasingly difficult,the traditional manual inspection of the approach has been very difficult to solve the huge gathering information on users of electricity.Therefore,the development of a complete set of power consumption data acquisition system has become an inevitable trend.In order to solve the user’s real-time electricity information collection,some U.S.and other countries proposed the concept of smart grid.Smart grid in real time using advanced information technology and efficient electricity grid for the collection of information,while the grid is important in all aspects of on-line monitoring of operating parameters to improve the safety and reliability of the power supply,reducing power loss in the transmission grid.Liaoning electric power information collection system introduced in this paper is to develop B/S structure is adopted to improve the development,the development of language in Java language,using Oracle as the database for data storage,data acquisition(DAQ)technology was used to power user electricity information acquisition.Liaoning electric power information acquisition system mainly includes the acquisition management module,data processing function module,sampling terminal equipment management function module and the user management module.Among them,sampling management module,including setting,sampling methods,three child functions such as task management module;Data processing module and include sampling data,abnormal data repair maintenance,four functions such as data statistic,data analysis module;Collection terminal equipment management module,including sampling terminal equipment maintenance,terminal equipment debugging,running terminal equipment inquiry,collection terminal equipment patrol management of four subsystems function module;Collect user management module,including low voltage user management,user management and so on high-pressure two child function module.
