Accompanying drawing explanation
Fig. 1 is flow chart of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the present invention is further elaborated.
Take that to realize Jiangsu 500kV rack be example.A real-time method for expressing for operation of power networks situation, the method is shown operation of power networks situation in the mode of dynamic graphical, Fig. 1 is flow chart of the present invention.Specifically comprise the following steps:
Step 1: equipment modeling and rack Data Collection.Equipment is carried out to modeling, extract the vegetarian refreshments of wanting that needs expression, and record these information with the form of setting, obtain rudimentary model; After rudimentary model completes, the form collection material according to set, stores rack data, obtains overall, a complete rack information.
In order to express major network grid structure, extract 500kV circuit, transformer station, power plant and form rack, and with the trend value of word annotation circuit, on the path of circuit, with the form of animation arrow, express the size of trend simultaneously, and be divided into 10 grades.Circuit needs recording equipment id, tolerance limit id, instantaneous value id, title and some position.Transformer station need to record the id of transformer station, tolerance limit id, instantaneous value id, title and some position.Power plant need to record the id of power plant, tolerance limit id, instantaneous value id, title and some position.Word annotation need to record instantaneous value id, title, coordinate, font, color.
Step 2: read rack information and draw basic model.Read rack information, by different device types, drawn out, obtain basic model; The device model of now drawing is basic state, does not carry out associated with concrete status data; On figure, only can see the positional information of equipment, its state information is not expressed.
According to the storage content of the various kinds of equipment of definition in step 1, from each system, collect necessary information, and unify summary record in a file, as be stored as an xml file.
Step 3: when reality is shown drafting, first use the information of definition in LoadConfig function load step 2, resolve successively each node content, and construct word annotation, transformer station, power plant and circuit object.Use canvasMain.Children.Add method to add on the picture of displaying the object of structure;
Step 4: also need to record overall word annotation list in the process of resolving each node.The total capacity value of the list Ji Ge transformer station of transformer station of the overall situation.For power plant, obtain the capability value of each unit.For circuit, need to record overall circuit list and the total capacity of each circuit.
Step 5: obtain real time information, upgrade rendering model.
Start independently thread, the rudimentary model key value according to storage, extracts corresponding status data from each operation system; The status data extracting is carried out to verification, check its correctness; If incorrect, abandon the data that this obtains, wait for that the next time cycle regains data; If data are correct, be set on corresponding basic model; Now basic model, after receiving new status data, can redraw according to new state value, changes the state of showing; , compare with default limit value meanwhile, change its state, and to end user's prompting or warning message; Thread, with the status data of the interval continuous updating model of setting, is expressed operation of power networks state in the mode of dynamic graphical in real time.
Start a thread, call GetRealData method and obtain real time data.Value below can obtaining successively in the method.
Step 501: the instantaneous value that obtains word annotation.According to the record in the list of global text annotation, call GetScadaData and obtain a collection of instantaneous value, whether the value that judgement obtains is qualified, if defective throw exception jumping out.If qualified, upgrade successively the record value in the list of global text annotation, according to different threshold value setting Show Styles, on graphical interfaces, word annotation redraws.
Step 502: the instantaneous value that obtains transformer station.According to the record in the list of overall transformer station, call GetScadaData and obtain a collection of instantaneous value, whether the value that judgement obtains is qualified, if defective throw exception jumping out.If qualified, upgrade successively the record value in the list of overall transformer station, according to different threshold value setting Show Styles, on graphical interfaces, transformer station redraws.
Step 503: the instantaneous value that obtains power plant.Record according in overall power plant (generator) list, calls GetScadaData and obtains a collection of instantaneous value, and whether the value that judgement obtains is qualified, if defective throw exception jumping out.If qualified, upgrade successively the value of exerting oneself of each unit, according to different threshold value setting Show Styles, on graphical interfaces, power plant redraws.
Step 504: the instantaneous value that obtains circuit.According to the record in overall circuit list, call GetScadaData and obtain a collection of instantaneous value, whether the value that judgement obtains is qualified, if defective throw exception jumping out.If qualified, upgrade successively each circuit, need to upgrade conductor loading and the sense of current, according to different threshold value setting Show Styles, on graphical interfaces, circuit redraws.
Step 505: one of thread dormancy regular time interval, as 10 seconds.This value can arrange as required.After dormancy period finishes, meeting is 501--505 step successively.
So far program can constantly be obtained new value, and upgrades graphical interface of user.The situation that surmounts tolerance limit in the value obtaining, can provide different display mode (flicker or color change) on interface, with call user's attention, thus the convenient abnormality that monitors operation of power networks.
The present invention shows operation of power networks situation in the mode of dynamic graphical, and the information such as realizing collection Line Flow, Substation Electric Equipment, transformer load, generator output of take is main data display and pattern exhibiting, and operation of power networks situation is provided in real time.
