4) utilize Dijsktra shortest path first to lay;
The cartographic information that utilizes 3S system to provide, considers that landform, earth's surface building distribute and subsurface geology situation, for every paths is weighted; Utilize dijkstra's algorithm to select to specify the shortest path of position between transformer station, finally determine that each point retains the limit of North and South direction or other limit;
5) adopt the modeling of vein distribution of shapes, optimize track laying trend
The straight line obtaining according to step 4) dijkstra's algorithm is laid electrical network, adopts the modeling of vein distribution of shapes to make the track of track laying, to meet the region intensive through user, optimizes track laying trend.
In the present embodiment:
The present embodiment comprises the following steps:
The first step, this embodiment is take certain city of China as example.18 districts of certain municipalization, totally 111 small towns, 99 subdistrict offices, 3661 neighborhood committees and 1704 villagers' committees, household register population 1400.7 ten thousand people, permanent resident population 1921.32 ten thousand people, land area is 6340.5 square kilometres, the density of population of calculating according to permanent resident population is every square kilometre of 3030 people.Certain city's economic total volume is positioned at first, Chinese each city for a long time, industry and commerce and service sector prosperity, and power consumption is large, but the problem that regional power grid still exists inadequate optimization, management to relatively lag behind.Jiang Jie lane distributes and is equivalent to population distribution, thereby infers the demand to electric energy.Distribute more intensive, population distribution is more concentrated, and power consumption demand is also just larger.
Second step, first sets clusters number, and algorithm is ended the parameters such as threshold value, then the each cluster centre of initialization on the density profile of lane, population street, with current cluster centre calculating subordinate function, then include other points in image in this region according to subordinate function, to upgrade each cluster centre.In the time that image is all included in classification, algorithm is ended.
Decide this area grade according near the ratio of black picture element part cluster centre, then peripheral region is included in the region of this grade.
With reference to Fig. 2 and Fig. 3, it is circular that the coverage of each transformer station should be approximately, because the each interior angle of regular hexagon is 120 degree, just can hold 3 interior angles at each splice point place, for the ease of analyzing, we are that regular hexagon Mi Pu analyzes by close circle paving problem reduction, at regular hexagon center, transformer station are set, and cover all users to make it top efficiency; Due to different brackets regional population density difference, the service area of transformer station varies in size, and therefore, the size that defines each region regular hexagon length of side is as follows:
Table 3-1 density of population area grade Classification Index
| Grade | 1 | 2 | 3 | 4 |
| The upper limit (%) | 100 | 25 | 10 | 5 |
| Lower limit (%) | 25 | 10 | 5 | 0 |
The 3rd step, it is circular that the coverage of each transformer station should be approximately, and for the ease of analyzing, we are that regular hexagon Mi Pu analyzes by close circle paving problem reduction, 2 grades of region regular hexagon Mi Pu of a part.Regular hexagon can Mi Pu, because its each interior angle is 120 degree, just can hold 3 interior angles at each splice point place.For each region, the position that transformer station sets up is regular hexagon center, covers all users to make it top efficiency.
Consider different brackets regional population density difference, and consider the service ability of a transformer station in reality, we determine that zones of different hexagon size is in practice as shown in the table.
Table 3-3 transformer station service range (distribution density) table
Figure is by an effect that region regular hexagon Mi Pu obtains wherein.
The 4th step, utilizes 3Dijsktra algorithm to be optimized power transmission network.
In the circuit network of whole UNICOMs, determine the part circuit that will delete, layout path is dropped into as far as possible under the prerequisite that is communicated with all supply nodes little.Region is being used after regular hexagon Mi Pu, if directly connect the center of adjacent hexagons, theoretical network is necessarily similar to equilateral triangle, application in this and reality does not meet, and the triangular net that every limit is all connected may cause the waste of line resource and can not fully develop the problem of line powering potential, therefore selects deletion circuit.Selection is by a line delete for North and South direction in network, only by remaining circuit, city is powered; Another kind of selection is the circuit that retains North and South direction, but deletes wherein one of two other limit.
Dijsktra algorithm flow is as follows: transformer station not connected to the network is joined the team, itself and transformer station are carried out to quicksort according to the loss to this transformer station, then select a longest line of Weighted distance to delete, if now two limits of the residue of the transformer station in the hexagon relating to are connected with other stations, gone out team, repeated this process for next transformer station in team.
Dijkstra's algorithm is routine techniques.
The 5th step, the modeling of vein shape and visual
In real physical environment, the distortion of plant leaf can be subject to the impact of diversified internal and external factor, for convenient research and without loss of generality, we consider that wherein the moisture of topmost influence factor leaf is supplied with. because in aging, the withered process of leaf, the model of vein has very important impact to the geometric configuration of leaf. and be the basis of our real simulation plant leaf distortion and set up vein distribution true to nature.To this, Runions had once proposed a kind of method of effective generation vein.The method is according to some botany phenomenons that show in leaf growth, the surface uniform of leaf distribute that some represent the growth vegetarian refreshments of nutriment, and the target of supposing thus the growth of vein be exactly arrive and connect on leaf each growth vegetarian refreshments, thereby for the each cell on the mesophyll in growth transports moisture and nutriment. like this, the profile of blade and the distribution of nutrition point have just determined the mode of vein growth, so just well the configuration of vein and leaf-shaped organic connections are got up.
In track laying, need to consider that the track of track laying meets through the intensive region of user as far as possible, and not necessarily straight line connection gained between 2 of this part region.The laying scheme obtaining due to dijkstra's algorithm is all that straight line is laid, and therefore can be optimized playing track.
In the time extending, realize according to following steps:
First from a transformer station, circuit extends take circle in scheming as unit along straight line, the relatively intensive region of inhabitant distribution in figure.Circle part, to intensive region skew, then finally extends to terminal, i.e. adjacent orthohexagonal center.
Apply after this algorithm, obtain transformer station and distribute and track laying distribution plan.The intensive treasured book of population distribution region transformer station lays relatively concentrated, and track laying is relatively intensive, and in suburb, electrical network is relatively sparse in to reduce resource consumption.
Implementation result:
The invention process effect, can carry out visual scheduling and operation, to improve the efficiency of scheduling, meets users' need for electricity.Meanwhile, by the visual demonstration of real-time grid information on load, can carry out macroscopical optimization to electrical network, also can finely tune electric weight schedule information.Following conditions permit, can obtain the real time fail information operating GPS of electrical network and remote sensing technology, removes the arduous and loaded down with trivial details of artificial collection from, further improves the intelligent degree of electrical network managing and control system, and acceleration disturbance is got rid of, and benefits consumers in general.
Power transmission network is laid and optimized, utilize dijkstra's algorithm to select to specify the shortest path of position between transformer station, as a kind of scheme, final definite by the line delete of North and South direction in network, only powered by remaining circuit;
Due in track laying, the track of considering track laying meets through the intensive region of user as far as possible, and not necessarily straight line connection gained between 2 of this part region, the laying scheme obtaining due to step 3) dijkstra's algorithm is all that straight line is laid, and therefore adopts the modeling of vein distribution of shapes further circuit track to be optimized; Method is as follows:
First from a transformer station, the circuit that small circle part represents extends take small circle in scheming as unit along straight line, and oval circle is the relatively intensive region of inhabitant distribution in figure.Small circle part is enclosed intensive region skew to ellipse, then finally extends to terminal, i.e. adjacent orthohexagonal center.
Apply after this algorithm, obtain transformer station and distribute and track laying distribution plan, the intensive treasured book of population distribution region transformer station lays relatively concentrated, and track laying is relatively intensive, and in suburb, electrical network is relatively sparse in to reduce resource consumption.
