Device for analyzing network communication record of digital transformer substation

The invention discloses a device for analyzing the network communication record of a digital transformer substation, which conforms to IEC61850 communication standard and provides service for the fault analysis, the engineering debugging and the relevant technology learning of the digital transformer substation. The device for analyzing the network communication record comprises at least one recording instrument and at least one analyzing instrument, wherein the recording instrument is used for on-line monitoring and recording communication between running entities (a monitoring device, a motion device, a protection/measurement and control device, an intelligent terminal, a combination unit and the like) in the transformer substation, carrying out on-line fault analysis and prediction, storing communication message periodicity as a file and generating briefing information for recording the file; the analyzing instrument provides various kinds of analysis, such as a communication process, message relativity, message mistakes and the like, and an analytical result is displayed in a view mode; the recording instrument and the analyzing instrument support various platforms, can run in the same machine and can also be installed in a distributed type; and when a distributed type installation mode is adopted, an analyzing exchanger of the network communication record is needed. The invention is applied to an electric power system and has the advantages of flexible installation and allocation, strong expansibility, low cost, long service life, visual display and comprehensive information.
