Description
Technical field
The present invention relates to Substation Automation System field, and in particular to a kind of alarm signal action of intelligent substation with
Temporal and logic relation analysis method.
Background technology
With the expansion and the propulsion of " big to run " System Construction of electrical network scale, large number quipments monitoring information is linked into control
Center, shows in chronological order, does not do any layering and reasoning and judging is processed, and operations staff's monitor task is heavier, it is easy to
Significant alarm signal is missed, delay is processed and caused the accident.When there is accident, semaphore is more, roll screen brush screen phenomenon occurs,
Operations staff is even more dazzled, at a loss as to what to do, it is difficult to concentrate on crucial points, affects the correct process to accident.Simultaneously as electrical network
The method of operation is changeable, and when an error occurs, protection, breaker may occur malfunction, tripping, and warning information can in transmitting procedure
Can lose, distort, these factors complicate will failure, operations staff may be difficult to make correct in the short time again
Judgement.
At present transformer station's alert mode adopts single dimension, the classification side such as such as switch changed position, protection signal, remote measurement be out-of-limit
Formula, it is clear that be not enough to carry out specific warning information accurate and sufficient description, while conventional alarm pattern is uniaxially
Offer suppresses/enables, the function such as confirm based on the push away picture, isolated warning information of measuring control point attribute definition.Alarm mode phase
To dullness, information is informed operations staff by the way of tiling simply, lack Consumer's Experience, including user interaction and customizable
Deng.And excessive information is provided, and is fatal thing for operations staff, in so various warning information, operation
Personnel can not rapidly hold keynote message.And as monitoring data lacks efficient preprocessing means, invalid alarm and time
Alert and take place frequently, cause main website further to analyze and lack reliable and stable data basis, although alarm direct transfers technology in part
Area is applied, and achieves positive effect, but which is substantially or emphasis solves the problems, such as Modulation recognition and transmission optimization, fails
Effectively solving core information refines problem, not yet fundamentally alleviates main website monitoring processing pressure.
Additionally, existing monitoring system of electric substation does not have the function of intelligent inference substantially, it is impossible to which the relevance of information is done
Go out to judge, and corresponding improvement is simply made in terms of information aspect, classification.Meanwhile, SCADA receive warning information also exist with
Lower problem：The signal of semantic meaning or extension repetition, dither signal interference, order are chaotic, useless to operation monitoring and analysis

The intelligent algorithms such as Petri network, information fusion.Expert system intelligent substation warning information process application in, although precision and
Efficiency improves a lot, but the defect for exposing is yet suffered from, and mainly has the construction of knowledge base under complex fault pattern inadequate
Complete, the factor such as alert mode of huge knowledge base and complexity constrains the diagnosis speed of expert system, the method for operation, protection
The change of configuration correspond to the adjustment of knowledge base rule causes maintenance workload very big, and protection device or breaker misoperation are easy
Cause to judge by accident or so that solution does not restrain so that its fault-tolerant ability is poor；Artificial neural network does not need construction knowledge base and reasoning
Machine, but the premise applied need to obtain enough sample sets in advance for its training, when electrical network is larger or connects more complicated,
The complete alarm sample set of acquisition is relatively difficult, and Algorithm Convergence is unreliable in addition, explains itself behavior and output result ability
It is very poor；The alert analysis processing method of Petri network is primarily present that fault-tolerant ability is poor, large scale electric network modeling has multiple shot array and asks
Topic, wrong report can not be recognized and fail to report information, there may be many solutions, and topological structure of electric and relaying configuration change situation；
The completeness and redundancy of the mainly information that information fusion technology is relied on, next to that multi-source information feature extraction and fusion method
Improvement, the precision of alert analysis process can be improved in theory and the diagnostic result of the overall situation, but in actual applications, letter can be obtained
The complete and redundancy of breath is difficult to obtain.
