in recent years, with digital substation emerging constantly, digital electric energy meter based on IEC 61850 protocol also emerges at the right moment. In view of the actual condition that the traditional electric energy meter calibration device can not calibrate the digital electric energy meter, in this paper, the R D and design for the digital electric energy meter calibration device based on embedded platform is introduced. The device adopts modular design, and is mainly consisted of digital power source, digital standard meter and man-machine interface, etc. Via the effective combination of various modules, the device can realize analog voltage and current collection, digital power output, and calculation, display and storage of various electric energies, etc., thus, completing the calibration on digital electric energy meter, at the same time, it also has the compatibility on calibration of traditional electric energy meter. Besides, the system also provides MMS communication function, and supports the acquisition of electric energy meter data model with such functions and the reading of data.
