Embodiment
Embodiment 1
The present invention is further illustrated below in conjunction with concrete case study on implementation.
1) be arranged to figure granularity filter condition, plant stand type be set to transformer station that electric pressure is 10kV ~ 220kV and switching station, mark measurement amount type selecting mark A phase current, meritorious, idle.From current electric grid model, search out qualified plant stand and line information, generate plant stand pel and circuit pel in mixing system drawing instrument, each plant stand pel is evenly distributed, and has generation circuit pel between the plant stand of connection to connect.
2) use the network map layout algorithm based on expansion mechanical model to carry out intelligent distribution to plant stand pel, this algorithm is to the innovatory algorithm based on Repulsion-Tension model algorithm;
Described is made up of node and two, limit key element based on the network topological diagram in the network map layout algorithm of expansion mechanical model.One clearly topological diagram should meet the following conditions: a) node is uniformly distributed .b) can not too press close between node and limit; C) limit is rationally distributed, avoids intersecting as far as possible.
By carrying out the topological graph of layout according to physical system modeling, using each plant stand as a node, each circuit is as a limit; Each node can regard the particle that has quality as; Each limit can regard the rubber band that has contractility as, and it has natural length (namely not by length during external force), if be elongated, then shows tension force; Asking of two nodes has mutually repulsion effect.
In order to make, for making node and limit keep appropriate distance, to give repulsion between limit and node, if the subpoint of node q is on the e of limit, then think may there is repulsion between q and e.Node can move under repulsion effect, and limit then maintains static.Repulsion and distance are inversely proportional to, if the hypotelorism between node and limit, node can be pushed in the other direction by repulsion; If the spacing on node and limit is greater than certain distance d, then repulsion is 0, produces excessive impact to avoid a limit repulsion to node layout.
For such physical system, to each particle (node) arbitrary position, it just can be allowed to run voluntarily according to physics law.In each step, what calculate that each corner is subject to makes a concerted effort, and allows this node move certain distance along resultant direction, until finally reach balance.Under ideal conditions, the initial velocity of all nodes is 0, and namely the overall initial momentum of system is 0, and system is not by the effect of external force, thus the conservation of momentum, the aggregated momentum of system is 0 always.This guarantees terminal stage or the internal node vibration of system, otherwise static, and overallly can not move to a direction or rotate.
To each plant stand node in system, obtain tension force suffered by each node and repulsion by tension force-repulsion formulae discovery, tension force and repulsion are added and obtain making a concerted effort, then by vector addition, Orthogonal Decomposition is the power in X-axis, y-axis direction.When system does not balance (initial situation), make each node along the direction displacement of making a concerted effort, thus X-axis, the y-axis coordinate information of each node can be obtained, one-tenth figure effect meets tidal current chart limit and intersects as far as possible few, Node distribution distance evenly, have the node of direct line to be distributed in the requirement at a place as far as possible, graphical distribution is rationally attractive in appearance.
3), after plant stand position is determined, the intelligent wiring of circuit will be carried out.The line requirements of automatic generation is smooth vertical and horizontal, will avoid intersecting between circuit as far as possible.Employing fan official algorithm carries out the intelligent wiring of circuit, makes circuit smooth vertical and horizontal, and ensures that intersection is minimum, and between many circuits, spacing evenly, rationally, and dislocation-free, nothing cover.
4) by the relevant parameter of circuit pel and plant stand figure element lane database, the measurement pel of this circuit of the other mark of circuit pel, circuit pel generates visual pie chart pel, the load factor of this circuit in this visual pie chart figure element database, circuit generates the dynamic power flow pel representing direction of tide and size, the visual electric network current diagram of final generation.
The feature of the present embodiment is 1) according to the electric network tide model in auxiliary tone system, in conjunction with actual flow data, automatically can generate dispatcher and carry out the supervision of auxiliary tone system load flow and the requisite trend figure of dispatching office; After the actual tide model of electrical network changes or changes, the trend graphic change caused, algorithm can accurately identify.2) setting of layout granularity, ensure that the trend figure that both automatically can generate the whole network, also according to actual needs, can generate the trend figure of the partial electric grid be concerned about.3) intelligent distribution can carry out autoplacement to each plant stand node of trend figure automatically, and ensure that plant stand Node distribution is even, have the plant stand of connection as far as possible close, the intersection between circuit is minimum, can not too press close between plant stand node and circuit.4) intelligent wiring ensure that shortest path between each circuit, and meets the smooth vertical and horizontal orthogonal graph custom that dispatcher uses.5) automatic marking of device parameter, makes the consistency of picture library be ensured.Visual pie chart, dynamic power flow make figure clear, attractive in appearance.
In sum: the present embodiment can generate the visual trend figure required for electrical network mixing system fast, for auxiliary tone systems engineering building and electrical network analysis research provide strong technical support, intelligence is mapping process automatically, not only can raise the efficiency, and greatly reduce the careless omission that human factor may cause, for power grid security, stable operation provide technical guarantee.
