Fig. 1 is that the power transmission and transformation equipment state anomalous identification of the present invention and the flow of plan for emergency handling automatic push method are shown
It is intended to.
Fig. 2 is the design structure diagram of emergency management prediction scheme storehouse.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
The application principle of the present invention is explained in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of power transmission and transformation equipment state anomalous identification and plan for emergency handling automatic push method, including with
Lower step：
Step 1：Establish emergency plan for accidents library；
Step 2：The exception of monitoring and identification power transmission and transforming equipment, by anomalous event storage to unit exception event buffer team
In row, and inspection management is carried out to the queue of unit exception event buffer, deletes the anomalous event of failure；
Step 3：Each accident prediction in emergency plan for accidents library is checked one by one, is judged that every accident prediction is associated and is set
Whether standby and corresponding Exception Type is present in anomalous event buffer queue, if not existing simultaneously, not triggering following mistake
Journey takes out the drawing road sequence defined in prediction scheme, automatic start draws road control, into prediction scheme automatic push flow if existing simultaneously；
As shown in Fig. 2, in the step 1, it is pre- including event emergency preplan table, accident emergency to establish emergency plan for accidents library
Case device relationships table, accident emergency draw road sequence table.
In the step 1, the overall information of accident emergent management prediction scheme defined in emergency plan for accidents table, including prediction scheme
ID, title, description, associate device quantity, sequence draw way amount etc., and emergency plan for accidents table is pre- by prediction scheme ID and accident emergency
Case device relationships table, accident emergency draw road sequence table association.
In the step 1, the associated faulty equipment letter of triggering prediction scheme defined in emergency plan for accidents device relationships table
Breath, associated with accident prediction is usually that one group of equipment draws road when all devices are abnormal in group by accident emergency
Sequence table starts automatically draws road control, into prediction scheme automatic push flow.Associated equipment source is in busbar, exchange line segment, change
Three kinds of device types of depressor.
In the step 1, accident emergency, which is drawn, needs opening for automatic drawing road when the emergency processing of accident defined in the sequence table of road
Information is closed, a prediction scheme corresponds to the roads a Zu La sequence, and the switch models of control derive from breaker table.
In the step 2, the anomaly monitoring of power transmission and transforming equipment includes：The out-of-limit monitoring of busbar grounding monitoring, busbar voltage,
Busbar voltage fluctuation monitoring, the monitoring of device current overload, transformer overload ability monitor that this 5 class monitors method, right by them
Busbar, exchange line segment, transformer are monitored, when an abnormality is discovered, anomalous event are stored in unit exception event buffer queue
In, storage content includes device type, device identification, Exception Type, time of origin.
In addition, since single prediction scheme needs multiple equipment while meeting exceptional condition just can to match, and the prison of equipment state
Survey process is asynchronous process, it is therefore desirable to establish unit exception event buffer queue, every exception is taken out from buffer queue
Event checks that each Time To Event, whether more than setting time, moves it if being more than with current time difference from caching
It removes, is not re-used as the foundation of accident prediction judgement, thus need to manage anomalous event in anomalous event buffer queue in step 2,
The anomalous event of failure is deleted in time.
In an embodiment of the present invention, the recognition methods of the busbar grounding is as follows：Obtain busbar three-phase voltage simultaneously
Three-phase imbalance value is calculated, when Voltage unbalance value is more than 15%, is judged as busbar grounding；The out-of-limit knowledge of the busbar voltage
Other method is as follows：Busbar real-time voltage crosses upper and lower limits and is then judged as voltage out-of-limit；The identification of the busbar voltage fluctuation
Method is as follows：In real time obtain busbar voltage same day maxima and minima, and calculate it is upward poor between current value and maximum value
Value calculates the downward difference between current value and minimum value, when maxima and minima difference is more than the 4.1% of rated voltage
When, it is judged as that busbar voltage fluctuation is critical out-of-limit, when being more than the 5% of rated voltage, is judged as that busbar voltage fluctuation is out-of-limit；It is described
The recognition methods of device current overload is as follows：The current value of real-time monitoring wire or main transformer equipment, when current loading rate reaches volume
Constant current 90% when be judged as critical out-of-limit, be judged as out-of-limit when reaching 100%, be judged as when reaching 110% serious out-of-limit；
The recognition methods of the transformer overload ability is as follows：The ratio of monitoring main transformer high-pressure side winding power and main transformer capacity in real time,
And corresponding threshold value is set according to temperature, ratio is judged as main transformer overload when being more than corresponding threshold.
In a kind of specific embodiment of the present invention, in shown step 3, two conditions need to be met by defining prediction scheme S：1) line
Road L electric currents are critical out-of-limit；2) busbar B line voltages are out-of-limit, and whether prediction scheme needs to check same in anomalous event buffer queue when checking
When there are " critical out-of-limit " event of circuit L and " voltage out-of-limit " events of busbar B, if not existing simultaneously, after not triggering
Continuous process, if existing simultaneously, prediction scheme successful match takes out the drawing road sequence defined in prediction scheme, and automatic start draws road control, into
Enter prediction scheme automatic push flow.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
