Embodiment Construction

[0018] The specific steps of digital substation fault inversion are as follows.

[0019] 1) On the specified sending port, import the CID files of one or more merging units.

[0020] 2) On the designated sending port, import the CID files of one or more protection devices or intelligent operation boxes.

[0021] 3) Import the Comtrade cfg file generated by the digital fault recorder.

[0022] 4) Match the SMV and GOOSE data in the CID file with the SMV and GOOSE data in the Comtrade file.

[0023] 5) Take out the data from Comtrade's dat file, and fill in the SMV and GOOSE messages according to the mapping relationship.

[0024] 6) Time stamp each frame of message according to Comtrade's recording frequency, and organize the data of one second.

[0025] 7) Drive the FPGA to send synchronously according to the calibrated time scale.

[0026] The specific steps of digital substation communication inversion are as follows.

[0027] 1) Import log files.

[0028] 2) Analyze t...

Abstract

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.

Description

technical field [0001] The present invention relates to the application of the general object-oriented substation event (GOOSE) of IEC61850 in the international standard "Substation Communication Network and System" and the sampling measurement value (SMV) transmitted through ISO / IEC802.3 in substation relay protection, specifically It is a digital substation fault inversion and communication inversion method based on the IEC61850 standard. Background technique [0002] The IEC61850 standard is the latest series of standards of "Substation Communication Network and System" formulated by the International Electrotechnical Commission TC57 working group to solve the interoperability problems faced by the substation automation system. This standard is supported by most mainstream manufacturers at home and abroad, and has become the only unified standard in the field of substation automation in the world. [0003] The tripping and closing information in the digital substation ba...
