Abstract: In view of the phenomena of lost frames,error codes and time delay in the digital energy metering process in the IEC 61850 protocol,this paper introduced a judgment method for such events as lost frames,error codes and time delay,which was based on the interpolation algorithm. The energy metering error rate caused by lost frames,er-ror codes and time delay was first calculated through analytical calculation in order to have an accurate and clear awareness of it. And then this paper proposed using the interpolation algorithm to calculate the energy metering error. The results were used to judge the seriousness of package loss so as to judge the status of data transmission network, and thereby alert and event records should be generated. The Matlab simulation results showed that the interpolation algorithm could accurately calculate the energy metering error caused by lost frames,error codes and time delay and provide a basis for the event alert of lost frames,error codes and time delay in the digital energy metering process.
