The application of smart substation technology has brought many opportunities to the power industry, but also caused many new problems and challenges. At present, with the large-scale promotion of intelligent substation based on IEC61850, there are many engineering problems which will not appear in IEC61850 protocol and are closely related to practical application. A device for online detection of electrical error is designed in the paper for the measurement deviation problem of “IEC61850-9-2 input digital power meter” in the new generation of intelligent substation. The characteristic of the device is that once the meter measurement error is detected within the set time interval, it will record the voltage and current waveform data within the interval in real time for error analysis and problem finding.
