Embodiment Construction

[0024] The method for optimally drawing the network planning wiring diagram includes the following steps:

[0025] (1) Partial adjustment of station and line positions in the wiring diagram:

[0026] a. Define the minimum distance A between graphic elements;

[0027] b. Select the dense area in the wiring diagram, then locate each graphic element in the dense area through coordinates, and then calculate the distance between each graphic element through the coordinates;

[0028] c. Take the distance B with the minimum distance between the primitives, and enlarge B to the minimum distance A for positioning;

[0029] d. Calculate the magnification ratio C of the distance between primitives, that is, C= A / B, and enlarge the distance of other primitives in the dense area by C times in the same proportion;

[0030] e. Finally, enlarge the distance of each graphic element in the wiring diagram by C times to complete the adjustment;

[0031] (2) Mapping of provincial network wiring...

Abstract

The invention discloses an optimized drawing method of a power grid planning wiring diagram. The partial regulation of stations and circuit positions is realized in a mode that distances among primitives are amplified with a same proportion, the regulation mode is simple, the viewing effect of the wiring diagram after the regulation is good, and coordinates are defined accurately and completely; and through coordinates of the wiring diagrams in a province diagram and a city diagram, the coordinate mapping is realized through using a fixed-point algorithm, and the power grid wiring diagram is prevented from being drawn repeatedly on the province diagram and the city diagram by drawing people.

Description

technical field [0001] The invention relates to the field of drawing a power grid wiring diagram, in particular to an optimal drawing method of a power grid planning wiring diagram. Background technique [0002] At present, the power system uses AUTOCAD to edit the grid planning wiring diagram. There are two characteristics in drawing the wiring diagram of power system grid planning: 1. The grid planning wiring diagram does not need to be precisely positioned like a geographical map. When the wiring diagram is printed and published, in order to show the grid structure of the grid in detail, some comparison In dense areas, local adjustments should be made; 2. Both provincial companies and municipal companies need to draw wiring diagrams for power grid planning. [0003] The traditional AUTCAD-based power grid planning wiring diagram drawing work cannot effectively work on the characteristics of the power grid planning wiring diagram, mainly because autcad cannot provide cros...
