[Abstract]:Because of the popularization of smart grid, the research of intelligent watt-hour meter is more and more important, and its calibration has a very important influence on the application of intelligent meter, and the research on it is also important. With the rapid development of computer technology and the importance of intelligent measurement and control to industrial production, Virtual instrument has gradually become an important development direction of instrument. Firstly, this paper briefly introduces the development trend of watt-hour meter, the significance and research status of ammeter calibration to power grid, and analyzes the deficiency of traditional calibrator. On this basis, an intelligent meter calibration platform based on virtual instrument is put forward. The platform has the functions of electric energy measurement, meter calibration, query, error analysis and so on. The principle of electric energy measurement of watt-hour meter is studied, and the high precision watt-hour meter is realized by programming. The whole design scheme and design process of the design platform are introduced emphatically. The graphic design based on LabVIEW can replace the traditional instrument. And it is superior to the traditional design method. Firstly, the principle of electric energy metering is studied. According to the principle, the intelligent meter with high precision is designed in virtual instrument and verified. An intelligent meter test platform is designed by using virtual instrument and database. The accuracy of the meter can be tested, and the source information and the test result of the meter can be stored in the specified database file, at the same time, The user can select the accuracy of the meter that has been measured. Finally, the error analysis is carried out, the possible error of the platform is analyzed, and the possibility of the error of the meter is analyzed, and the corresponding solving measures are given. In combination with the rapid development of communication technology and computer technology, the calibration device of electric energy can be studied to design the calibration platform of electric energy meter and establish standardization. The unified calibration data management and test application platform. Finally, provide the relevant data theoretical basis for the intelligent meter automatic detection, efficient and economical operation, guarantee the quality measure formulation, In order to improve the automation level of the intelligent meter in the production process, and can automatically save all the calibration data, and achieve the goal of ensuring quality and improving efficiency.
