6 Plot Data On Geographical Map

Step 5 Working with the Local Repository

6 Plot Data On Geographical Map

We can now work with the data in the repository as we would with data loaded from a file. The main difference is that the user will be prompted for a description that will be added to each save (known as a commit). We will continue with the editing of the CIM representation using the IEEE 14 Bus Network in the local repository.

6.1 Adding Geographical Locations

    1. Select Editors and Open Geospatial Editor from the main menu or click on the 30icon in the toolbar.
    2. Select the IEEE 14 Bus Network from the Local Repository→IEEE Test Networks folder and click Next.
    3. If there is a desire to change the coordinate system then this can be done on this screen. The default is WGS 84 which is a latitude/longitude in decimal degrees system.
    4. Ensure Allow Editing and Allow Placement are enabled and click Finish to open the Geospatial Editor.
    5. This will also change the Workbench perspective from Cimphony to Geographical. This changes the position of the different views and windows. This is shown by the icon selected in the top-left below the toolbar. You can alternate between the perspectives by changing this selection.
    6. Return to the Geographical perspective and zoom in to the desired region on the map where the substations will be plotted either by double clicking on the area or using the zoom slider. In this case we will select Scotland (the North of the island of Great Britain).31
    7. Expand the Primary Substation under Sites in the legend of the map to list all the Substations that have multiple voltage levels.
    8. Click on a substation then double click on the location on the map where this substation should be placed. An icon will be added to the map and the substation name will go from green to grey to indicate it is placed.
    9. Click on the icon to select the corresponding entry in the Cimphony Browser.
    10. This process can be repeated for all primary substations and similarly for substations (any substations with only a single voltage level).
    11. Substations can also be placed on the map by right clicking on an already placed substation and clicking on a green name in the options popup (which indicates another substation the selected substation interconnects with). Double clicking on the map will position this substation and draw any corresponding lines.32
    12. As this is a simple map we can disable the Clustering option (enabled by default) by clicking on the Clustering On in the Toolbox.
    13. You can also toggle the map style from the default simple view to the standard Google Maps detailed view by clicking Simple Map Style which changes it to Detailed Map Style then back again.
    14. Position all the stations on the map; note that the lines are automatically drawn between the stations.
    15. Station locations can be altered by dragging and dropping the icon.
    16. The labels for the stations can be toggled by clicking on Show Labels in the Toolbox.
    17. Additional points can be added to lines by double-clicking on the lineand then dragging the small circular icon that appears (to make this easier the line width can be altered by toggling between the default thin and thick line using Line Width in the Toolbox).33
    18. Add some suitable bend-points for the lines.
    19. Adding a location will automatically add or update a Location object inthe CIM model associated with the Substation or ACLineSegment, adding, removing or modifying PositionPoints as required.34
    20. Save the updated model by selecting File→Save from the main menu. You will be prompted to enter a commit message (by default this lists the number of object changes but we can add a more detailed message such as “Addition of geographical data”. Click OK to commit the changes.
