Step S311, if SQMUM value returns 0, noses in GOOSE information whether displacement of the data in actual message.
Step S312, if the data in actual message do not have displacement in GOOSE information, judges that obtaining GOOSE information becomes for empty.
Step S32, if in step S312, judges that obtaining GOOSE information becomes for empty, sends alarm, and records warning information.In addition, in step S32, thrown by the overall situation and mono signal data set mistake function and move back pressing plate control.
Further, if this GOOSE information is the first frame receiving, and SQNUM is 0, represents that the analytical parameters of this GOOSE information is in the state of no initializtion, now do not carry out alarm.
The intelligent substation operation information transmission analysis on its rationality method of embodiment of the present invention, by judging whether GOOSE information is empty change; Judging that obtaining GOOSE information becomes for empty, send alarm, and record described warning information, and then be there is to empty change in the operation information producing in substation operation process and analyse processing, be conducive to subsequent treatment personnel to the operation troubles of transformer station analyze, localization process.
