Accompanying drawing explanation
Fig. 1 is monitor state initial in the embodiment of the present invention；
Fig. 2 is the monitoring of In Hangzhou Region of Zhe Jiang Province operation of power networks data in the embodiment of the present invention；
Fig. 3 is the map rendered plus hotspot graph in the embodiment of the present invention.
Detailed description of the invention
With detailed description of the invention the present invention it is further elaborated below in conjunction with the accompanying drawings and illustrates.In the present invention, each is implemented
The technical characteristic of mode, on the premise of not colliding with each other, all can carry out respective combination.
The present embodiment select Hangzhou as region to be shown.Basic scheme is for utilize hotspot graph to show respectively on geographical map
Ground voltage and payload, color scale reference gas warm point diagram, voltage or load value are the highest, closer to positive red, along with number
Value reduces, and gradually becomes yellow, green, blueness.
The present embodiment, using the map products of company of Baidu as base map, is loaded into what map rendered as hotspot graph by API
Basis.Its initial monitor state is as shown in Figure 1.The monitoring of service data is as shown in Figure 2.Based on this map, carry out electricity
Force system voltage or the visual control of load, specifically comprise the following steps that
(1) from SCADA system, In Hangzhou Region of Zhe Jiang Province each system median generatrix voltage or load data are read in real time.
(2) utilize distance weighted interpolation calculation to go out the voltage virtual value of blank space between bus, make region, Hangzhou on map
The corresponding numerical value of each point in scope to be shown, thus discrete node voltage coloring problem is converted into continuous print joint
Point voltage coloring problem.
The circular of distance weighted interpolation is as follows:
For any point P in the range of Hangzhou on map, search nearest three of this periphery and there is busbar voltage or negative
The discrete point of lotus data, its nodal value is respectively V1, V2 and V3, voltage or the virtual value V of load at some PPFor:
(wherein diRepresent the i point distance to P point)
(3) colour band is utilized to define different rgb values to different voltages or load value, according to the numerical value corresponding to each point,
Carry out color mapping, make the corresponding a kind of color of each point.Colour band is the continuous colour band being extended to blueness by redness, and color maps
Process gives redness, yellow, green, blueness the most successively by voltage or load value.
(4) it is loaded into map by the API of Baidu's map, according to the color mapping result obtained in above-mentioned steps, by focus
Figure is covered in after arranging transparency on Baidu's map, it is achieved the hotspot graph in the range of Hangzhou renders, with the electricity in visualized map
Force system voltage or load.Monitoring personnel can according to the color of hotspot graph intuitively voltage or load to power system supervise
Control.Said process arranges just to circulate every 1 second and repeats above step, with Dynamic Announce hotspot graph, real-time monitoring system state.
Geography information, based on GIS-Geographic Information System (GIS), is tied mutually by this method with power system node service data
Close, the step generation node service data such as is mapped and render by bus digital independent, the calculating of virtual value, color isocontour
Method for visualizing.Hotspot graph and contour map can effectively reduce dispatcher and find the time needed for system exception and fault,
It is to visualize explicit representation the most efficiently.But when troubleshooting, hotspot graph or contour map cover and are likely to result in identification difficulty,
Affect treatment effeciency, therefore display and the hidden function module of hotspot graph can be set during display, heat can be used as required
Point diagram.
Embodiment described above is the one preferably scheme of the present invention, and so it is not intended to limiting the invention.Have
Close the those of ordinary skill of technical field, without departing from the spirit and scope of the present invention, it is also possible to make various change
Change and modification.The technical scheme that the most all modes taking equivalent or equivalent transformation are obtained, all falls within the guarantor of the present invention
In the range of protecting.
