Description of drawings
Fig. 1 is a visual pattern message analysis method flow diagram of the present invention.
The normal waveform of Fig. 2 system and several kinds of signature waveform examples that network is unusual.
Embodiment
System adopts the data acquisition CPU board that message (SV, GOOSE, MMS etc.) is received storage, and carries out basic analytical, classification.
On the analysis backstage all kinds message being carried out tree structure resolves and analysis of oscillogram.
Tree structure is only resolved all kinds is resolved separately, and the numerical value of each field in the analytic message, and the full station model of combination digital transformer substation 61850 are resolved message comprehensively, shows institute's interior each equipment relevant numerical in corresponding station.
The oscillogram display pointer is to resolving SV and the message data of GOOSE message in the time; Full station model in conjunction with digital transformer substation 61850; Equipment in the corresponding power station of continuous message data is carried out the demonstration of oscillogram; The graphics edition function is provided, can carries out convergent-divergent, roaming and the direct positioning action of exception message figure.
Unusual waveforms analysis and message location refer to provide the anomaly analysis result simultaneously from the direct analysis waveform characteristic of oscillogram that shows, directly locate the corresponding network message of unusual waveforms through the operation figure.Be divided into two kinds of situation:
1. the electric power system system failure (slope and value are all in a limited range for system disturbance, power transmission line line short etc.) can directly be located corresponding message and confirm mutually by unit faults recorder analysis experience and software analysis in addition.
2. network failure, direct analysis waveform characteristic (slope is unusual, be worth unusual etc.) is located the position of unusual waveforms; Amplification provides anomaly analysis result (such as frame losing, incorrect order is retransmitted etc.) simultaneously with demonstration directly perceived; Can operate figure and locate corresponding message, search the fault source, solve network problem.
The basis of unusual waveforms analysis and message location technology is that the waveform essential characteristic of electric power system is continuous sinusoidal waveform, and its slope also is continuous.Under the normal condition be that the waveform that ordinate value is drawn also is a sinusoidal waveform with the slope, even if the moment that system breaks down, slope is bigger, also within a limited scope.Even primary equipment does not put into operation in addition; As long as the collector and the SV network operation; The sampled value waveform also has the fluctuation up and down of a non-zero, can not occur absolute zero for a long time, if because the direct current offset of gathering; The sampled value waveform has a fluctuation up and down around the direct current offset value, can not occur for a long time on a value and has no to change.
The basic principle that unusual waveforms is analyzed:
1, through the double sudden change of slope (when the sampled value slope of frame losing itself is very big near maximum in; Generally speaking electric power system three phase samplers send through same MU; Three is symmetrical; Can find such characteristic in the synchronization frame losing) judge and to lose a frame that three times of sudden changes judge and lose two frames etc., need judge actual generation systems fault rather than network failure through the failure wave-recording locking that suddenlys change certainly.
2, judge incorrect order through the slope sign mutation, the slope sign change is that its value is less under the normal condition, if when slope value is big, sign mutation takes place then MU generation message incorrect order can be described.
3, the three-phase channel wave just as the time slope be zero, the time is shorter, judges and retransmits.
