Testing method for synchronization performance of IEC61850-based digital measurement and control device

The present invention discloses a method for testing the performance of the synchronization digital monitoring and control device based on the IEC61850, it is simple, accurate, time-saving features, by changing the digital protection relay tester sample counter output value of each channel sampling interval, simultaneously combining unit so that different values ​​for different output sampling counter number, checking Control device displays the output value corresponding to the sampled value to determine whether or not its synchronization performance; if the corresponding, correct performance of the synchronization; If it does not, then the synchronization performance is incorrect.
