Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is entered
Row further describes.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
Determine the present invention.
Below in conjunction with the accompanying drawings the application principle of the present invention is explained in detail.
As it is shown in figure 1, a kind of power transmission and transformation equipment state anomalous identification and the automatic method for pushing of plan for emergency handling, including following
Step:
Step one: set up emergency plan for accidents storehouse；
Step 2: monitor and identify the exception of power transmission and transforming equipment, stores in unit exception event buffer queue by anomalous event,
And carry out checking management to unit exception event buffer queue, delete the anomalous event lost efficacy；
Step 3: check each bar accident prediction in emergency plan for accidents storehouse one by one, it is judged that the equipment of every accident prediction association and
Whether corresponding Exception Type is present in anomalous event buffer queue, if exist the most simultaneously, and the most not triggering following process,
If exist simultaneously, take out and draw road sequence defined in prediction scheme, automatically start and draw road control, enter prediction scheme and automatically push flow process；
As in figure 2 it is shown, in described step one, set up emergency plan for accidents storehouse and include therefore emergency preplan table, emergency plan for accidents
Device relationships table, accident emergency draw road sequence table.
In described step one, 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 passes through prediction scheme ID and accident emergency
Prediction scheme device relationships table, accident emergency draw road sequence table association.
In described step one, trigger the faulty equipment information of prediction scheme association defined in emergency plan for accidents device relationships table, with
Usually one group of equipment of accident prediction association, when all devices all occurs abnormal in group, draws road sequence by accident emergency
Table automatically starts and draws road control, enters prediction scheme and automatically pushes flow process.The equipment source of association is in bus, exchange line segment, transformation
Three kinds of device types of device.
In described step one, accident emergency needs the switch automatically drawing road to believe when drawing the emergency processing of accident defined in the sequence table of road
Breath, a corresponding Zu La road sequence of prediction scheme, the switch models of control derives from chopper table.
In described step 2, the anomaly monitoring of power transmission and transforming equipment includes: busbar grounding supervision, the out-of-limit supervision of busbar voltage, mother
Line voltage pulsation supervision, device current overload monitor, transformer overload ability monitors that this 5 class monitors method, right by them
Bus, exchange line segment, transformator monitor, when an abnormality is discovered, anomalous event are stored in unit exception event buffer team
In row, storage content includes device type, device identification, Exception Type, time of origin.
Just can mate further, since single prediction scheme needs multiple equipment to meet abnormal condition simultaneously, and the monitoring of equipment state
Journey is asynchronous process, it is therefore desirable to sets up unit exception event buffer queue, takes out every anomalous event from buffer queue,
Checking whether each Time To Event and current time difference exceed the setting time, if exceeding, it being removed, no from caching
It is re-used as the foundation that accident prediction judges, thus step 2 needs to manage anomalous event in anomalous event buffer queue, in time
Delete the anomalous event lost efficacy.
In an embodiment of the present invention, the recognition methods of described busbar grounding is as follows: obtains bus three-phase voltage and calculates
Three-phase imbalance value, when Voltage unbalance value is more than 15%, it is judged that for busbar grounding；The identification that described busbar voltage is out-of-limit
Method is as follows: bus real-time voltage is crossed bound scope and is then judged as voltage out-of-limit；The identification side of described busbar voltage fluctuation
Method is as follows: obtains busbar voltage maxima and minima on the same day in real time, and calculates the upwards difference between currency and maximum,
Calculate the downward difference between currency and minima, when maxima and minima difference exceedes the 4.1% of rated voltage, sentence
Break critical out-of-limit for busbar voltage fluctuation, when exceeding the 5% of rated voltage, it is judged that out-of-limit for busbar voltage fluctuation；Described equipment
The recognition methods of current overload is as follows: monitoring wire or the current value of main transformer equipment in real time, when current loading rate reaches specified electricity
Stream 90% time be judged as critical out-of-limit, reach to be judged as when 100% out-of-limit, reach to be judged as when 110% the most out-of-limit；Described
The recognition methods of transformer overload ability is as follows: monitor the ratio of main transformer high-pressure side winding power and main transformer capacity, and root in real time
Setting corresponding threshold value according to temperature, ratio is judged as main transformer overload when exceeding corresponding threshold.
In a kind of specific embodiment of the present invention, in shown step 3, definition prediction scheme S need to meet two conditions: 1) line
Road L electric current is critical out-of-limit；2) bus B line voltage out-of-limit, prediction scheme needs to check in anomalous event buffer queue when checking and is
No " critical out-of-limit " event that simultaneously there is circuit L and " voltage out-of-limit " event of bus B, if exist the most simultaneously,
The most not triggering following process, if exist simultaneously, then the match is successful for prediction scheme, takes out and draws road sequence defined in prediction scheme, automatically opens
Dong La road controls, and enters prediction scheme and automatically pushes flow process.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technical staff of the industry
It should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description, the present invention is simply described
Principle, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these change
Both fall within scope of the claimed invention with improvement.Claimed scope by appending claims and etc.
Effect thing defines.
