Half-automatic Schematic Map Production

With this solution, schematic maps can be created based on the Smallworld sector-specific application for electricity. The ITS Schematic Map Assistant creates these maps using a list of components and objects depicted in the overview map. Topology is also reconstructed. With the help of additional drawing tools, a plot visualisation is created based on the original version.

  • Optimised schematic map creation and documentation
  • Creating a list of objects in the main menu
  • Topologically complete schematic map creation
  • Supply areas are visualised in colour
  • Creating real-life schematic plans

Product Description

Initial Starting Point

Utility companies usually edit medium voltage schematic maps in a CAD or DXF format. As a result, these plans are documented and updated separately. Furthermore, a CAD-based schematic map can not be evaluated topologically meaning that circuit visualisations are impossible. In order to break away from this static solution and to use an analytical and GIS-based approach, medium voltage schematic maps for electricity are deployed in Smallworld GIS. One of the main requirements is to apply DIN-conform layouts of the current map.

Schematic Map Assistant

In the ITS Schematic Map Assistant, power plants can be edited and documented in a special schematic map for electricity that is topologically derived from an overview map. Based on topological connections in the overview map in conjunction with plant circuit diagrams, the ITS Schematic Map Assistant produces maps that depict switches and cables within the plant as well as individual routes. This reduces editing work for users. It is only necessary to create a line which intersects with the power plant in the schematic map.

Creating a Schematic Map

The schematic map is created via the main menu in combination with existing electricity assets that are available in a list. After selecting a power plant, the corresponding geometry can be positioned in the unique internal world of the schematic map. As soon as another power plant is connected, the advantages of the Schematic Map Assistant come into play. All further switching elements and internal cables are automatically placed in their correct location, producing a topologically correct schematic map containing geometries for all components.

Different Visualisations

It is also possible to create different schematic map visualisations using different styling methods. This is done in a separate design application. Geometries are maintained in their original form. Styling methods are applied to depict objects differently, for example, according to their status or slightly displaced and using different symbols and labelling. The following two illustrations show identical excerpts of the same schematic map, but in two different style variations. One in the default style and the other in a electricity-specific style. This layout is created using additional design tools. Some of them are listed below:

  • Instead of busbars, a power plant symbol is placed at outgoing route intersections similar to the overview map.
  • Multiline power plant labelling.
  • To label routes, the shortest section of the cable route is determined.
  • Medium voltage switches in transformer stations are placed on intersections of busbars and internal cables.

With the help of these design tools, schematic maps for electricity are visualised in a style that electricity departments recognise. This increases acceptancy amongst users.
