As the lack of laboratory testing methods for dynamic load metering error of digital electric energy meter used in smart substation, a kind of dynamic error test equipment of digital electric energy meter, which adopts OOK dynamic test signal model, is developed in this paper. Firstly, a discrete OOK dynamic test signal model is intro- duced; secondly, the overall hardware design scheme of equipment is put forward, based on the scheme, this paper proposed the method of OOK signal generation, and IEC 61850-9 protocol SMV group packing. The final test shows the signal waveform generated by the device can exactly meet the requirements of the OOK model, and the test is conducted in some domestic digital electric energy meter company, and the result shows that the equipment can effectively test the dynamic error of digital electric energy meter.
