Description

A kind of Net Frame of Electric Network figure autoplacement method based on the plant stand geography information

Technical field

The invention belongs to the dispatching automation of electric power systems technical field, be specifically related to a kind of Net Frame of Electric Network figure autoplacement method based on the plant stand geography information.

Background technology

In power network dispatching system, the monitoring that the circuit between plant stand, plant stand and trend thereof distribute is the responsibility of dispatching automation.In current supervisory system, draw power system network topology diagram and electric network current diagram, be all by maintenance person or slip-stick artist according to monitored electrical network real topology, utilize the dispatching system drawing instrument, hand drawn out,

For the rationality of the energy management system operation and control result that guarantees dispatching center, need to realize overall tide model by the mutual real-time model in upper and lower level dispatching center; The electric network model of energy management system not only comprises the electric network model of local maintenance, and comprises the electric network model that the superior and the subordinate dispatching center safeguards.Owing to exist upgrading not in time, length consuming time, easily make mistakes, later maintenance inconvenience, inaesthetic shortcoming, the method of manual maintenance electric network current diagram is no longer applicable, need to automatically generate overall tidal current chart according to overall electric network model, utilize the geography information of the crucial plant stand of minority (plant stand of generating plant stand, 500kV plant stand, provincial capital position etc.), Net Frame of Electric Network figure is drawn automatically by software, workload is little, and picture is attractive in appearance, easy to maintenance.

The Net Frame of Electric Network figure in the past used at dispatching communication above the provincial level center is the drawing instrument that utilizes the dispatching automation of electric power systems software platform by maintainer's manual drawing, data message needs manual the placement, in the situation that network size is larger, draw Net Frame of Electric Network figure and often need the man-hour of several days, increasing new plant stand and circuit may need to adjust the place and route of original Net Frame of Electric Network figure, also may need to adjust whole picture structure in order to increase new data message, all rely on manual completing often can't reach efficient, accurately, the effect that fiduciary level is high.The nationwide integrated power grid rack figure of take is example, because it need to show each province's Power grid structure, so scale is very huge, and the probability that new plant stand puts into operation is higher than the probability of some provinces, Net Frame of Electric Network figure need to constantly revise, each modification all needs placement-and-routing again, and only making place modification have to a couple of days consuming time.Generally speaking, original technological means can't adapt to the demand of fast-developing electrical network scale, also can't meet the dispatcher the faster more fully demand of electric network information.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of Net Frame of Electric Network figure autoplacement method based on the plant stand geography information, can realize the autoplacement of the Net Frame of Electric Network figure based on geography information, figure has more intuitive; Support newly to add or the figure while deleting plant stand upgrades in time, reduced artificial editing graph careless omission and mistake, improved greatly the efficiency of artwork maintenance.

In order to realize the foregoing invention purpose, the present invention takes following technical scheme:

The invention provides a kind of Net Frame of Electric Network figure autoplacement method based on the plant stand geography information, comprise the following steps:

Step 1: the electric network composition data importing is arrived to the autoplacement system;

Step 2: form initial Net Frame of Electric Network figure;

Step 3: automatically adjust and optimize the plant stand position;

Step 4: the plant stand position after automatic adjustment optimization is revised.
