Description of the drawings
Fig. 1 is the flow chart of the digitlization selection method of the UHV transmission line of the present invention.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is described in further details the present invention:
The invention discloses a kind of digitlization selection methods of UHV transmission line, and this method is for UHV transmission line Layout of roads.Here is specific embodiment.
Disclosed by the invention is a kind of digitlization selection method of UHV transmission line, and this method is based on polynary geographical letter Breath system, and Computerized three-dimensional display technology is combined, it can realize the digitlization of the route selection of UHV transmission line, Fig. 1 is should The flow chart of selection method, this approach includes the following steps:
1), first create a project about target line, collect relevant information.The acquisition of the relevant information includes extra-high The terminal information and planning transmission capacity of pressure transmission line;The disengaging line architecture of start-stop substation or electric substation, transposition;Shaft tower The section of grounded-line, model.It also needs to input general Regulations simultaneously, such as standardized designs data, each voltage class electricity Gas, exploration specification etc.;And with the relevant restrictive data of this engineering, such as according to property file, approved document, document of agreement, original Then property and mandatory term etc..
2), in conjunction with polynary GIS-Geographic Information System and Computerized three-dimensional display technology, acquire existing polynary geography information number According to the general case of generation route choosing scheme.In the inventive solutions, using three-dimensional geographic information system (Geographic Information System, GIS)Acquisition, integrally face image data, altitude data, thematic information number According to, planning and built track data etc., as the underlying platform of digitlization route selection, and it is big to preliminarily form a circuit automatically Scheme.
Realize that the technical solution of digitlization route selection enormously simplifies the intensity of route selection work using three-dimensional geographic information system, It improves work efficiency.Meanwhile digitlization route selection platform in this way by all relevant information comprehensive displays together, and Route selection is carried out in three-dimensional artificial scene, substantially increases accuracy, the validity of route choosing.
Meanwhile using power grid thematic data, power grid spatial data, passage way data in three-dimensional geographic information system, with And existing control point in system(Evacuation point)Information can automatically generate a big scheme in path, as by system platform The general case of route choosing scheme mainly considers known evacuation point and tortuous system information, and foring one theoretically can be with By path corridor.
3), collaboration introductory path agreement;Military area, waters protection zone, airport control including synergy route choosing The information in area, nature reserve area, scenic spot, minery, planning region and hazardous area, and sign Path First.
Meanwhile verifying the related keynote message of the big scheme of circuit, potential information;Including to crucial scissors crossing Points And lines road Corridor nervously band supplement exploration;Field investigation to hydrometeorology;Exploration of drilling to geological-hazard-prone area area.But also It enriches, improve existing polynary geographic information data;Introductory path agreement and related keynote message are stored to existing polynary In GIS-Geographic Information System.
4), carry out the adjustment of route choosing scheme and perfect.First, the airline of circuit starting point and ending point is established. The airline can intersect with the figure layer region avoided is needed, real by increasing some corner pile points with Digital Algorithm Now to the evacuation in these regions.Secondly, Decision Making of Line Schemes is primarily determined on the basis of the airline of optimization, carries out automatic preliminary row Position, the cost of further quantum chemical method circuit do deep Decision Making of Line Schemes comparison.Polynary geography information after being improved according to supplement System carries out the optimization of Decision Making of Line Schemes, and according to detailed information, constantly improve, until forming final Decision Making of Line Schemes.It is finally right Final Decision Making of Line Schemes carry out it is perfect, particularly as be on the basis of the final Decision Making of Line Schemes of circuit selection scheme, whole process consider Determining line corridor sideline range is supplemented along marking and drawing across house, scissors crossing, across the relevant information of tree.
In the inventive solutions, by three-dimensional geographic information system, housing demolition amount, trees along circuit are calculated Cutting capacity.And by the analytic function of three-dimensional geographic information system, circuit is calculated by the ratio in mountain area, hills, Plain, is subtracted Few line disconnection.
5), determine final route choosing scheme, and by route selection resulting number, using digitlization route selection as a result, ranking, Quantify the construction cost of alternative route engineering, generate related drawing and report, including detailed line map, sea level on the average figure, Circuit plane cross section and circuit Statistical Analysis Report.
The circuit plane cross section includes within the scope of determining corridor sideline along the line across house, scissors crossing, across tree etc. Information.The circuit Statistical Analysis Report includes mountain area, Plain, each accounting example in hills, is counted across each voltage class circuit, across each Grade ice formation dirt area counts, average strain section statistics and buckling factor.
Three-dimensional geographic information system in the present invention(Geographic Information System, GIS)Using high definition Clear satellite image, timeliness is good, and precision is high, realizes that route choosing Comprehensive considers complicated ask on this system Topic, reduces the uncertainty of circuit, improves the confidence level of circuit establishment.
Route choosing in the present invention applies newest high-resolution satellite image, can preferably optimize circuit, shorten circuit Length reduces corner quantity and housing demolition amount, saves construction investment;It, can be with meanwhile according to newest high-resolution satellite image Data objectively count the information such as house, high-grade water system, road.Reliable data are provided for feasibility study, are deepened The feasibility study depth of Decision Making of Line Schemes provides objective comprehensive data basis for objective evaluation.
Digitized result in the present invention provides intuitive readable for designing institute and local government and associated mechanisms, unit Take the technical data that analysis uses.Meanwhile being counted in circuit selection course in the present invention, the basic information data being calculated, Such as road, water system, house, forest can be that other need the engineering of relevant rudimentary information directly to take away use, improve society Meeting production efficiency, economizes on resources.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes still within the protection scope of the invention.
