Method for fault inversion and communication inversion of digital substation based on IEC (International Electrotechnical Commission) 61850 standard

The invention discloses a method for fault inversion and communication inversion of a digital substation based on the IEC (International Electrotechnical Commission) 61850 standard. At present, the digital substation based on the IEC61850 standard is basically internally provided with network data recording devices only taking charge of intercepting and storing original communication messages andnot having the function of communication inversion. In the invention, the method for fault inversion and communication inversion of the digital substation based on the IEC61850 standard comprises thefollowing steps of: analyzing Comtrade recording files generated by a digital fault recorder, and repeatedly transmitting the acquired data on each recording time point according to the recorded frequencies so as to realize the inversion of the fault data; and analyzing recorded files generated by the recording devices in the substation, and reducing and transmitting the files according to the recording time corresponding sequence of each data in the recorded files so as to realize the inversion of the communication process. The invention realizes the fault inversion and the communication inversion by a simple manner, and the combination of the fault inversion and the communication inversion provides an excellent auxiliary effect for substation workers to find out the reason of faults.
