Drawing and Editing a Grid
Views
Grid elements can be added in different views
- Map view
- Schematic view
- Split view
TIP
Expand the drawing area by clicking in between the editor and grid view windows.
Add New
You can add new grid elements by clicking on the desired icon or using the shortcut corresponding to the element you want to add, for example B for adding a new bus. An info message will appear at the bottom of the grid to guide you through certain steps of the grid editing process.
TIP
- Use fullscreen mode for a more immersive experience.
- Use scrolling for zooming in the activated grid viewer.
- Use Esc to abort a process of adding a new or editing an existing grid element.
- Use Enter to complete a process of adding a new or editing an existing grid element.
Bus
Click in the schematic view or in the map view to add a new bus. Click on a branch to add a new bus and splice the line.
Line, Connection, Transformer
Drag from the source bus to the target bus to add a new branch (line, connection or transformer).
If a Line or Connection is drawn in the map view, its geographical path can be updated by clicking on it and then in the grid inspector on the right. Recalculate the line length based on the line's coordinates by clicking on next to the Length attribute in the grid inspector.
Voltage Regulator
Click a line to add a new voltage regulator.
Switch, Fuse
Click on a branch and then on one of its connectors to add a switch.
Protection Device
Click a switch to add a new protection device.
Load, Generator, Storage, Network Feeder
Click a bus to add a new load, generator, storage or network feeder.
Station
Click in the schematic view or draw a polygon in the map view to add a station.
Lines and connections can be connected to the inside of the station by dragging them from a bus to the station and then connecting to any bus that is already present inside the station.
Edit
Grid Inspector
Clicking on a grid element opens the grid inspector for that element on the right side. There it is possible to edit the attributes of the element.
Component Overview
Element attributes can also be edited in the Component Overview.
TIP
The table can be expanded to the full width of the screen by clicking on the button in between the editor and grid view windows.
TIP
The table supports most shortcuts known from Excel, like
- copy + paste of values between cells
- dragging down to fill cells with the previous value
- and more...
Multiple Selection
To select multiple elements use the icon from the toolbar or keep Ctrl / Cmd pressed while dragging an area over the desired elements. Alternatively use Ctrl / Cmd + A to select all elements.
TIP
Individual elements can be selected by keeping Ctrl / Cmd pressed and clicking on the desired elements.
INFO
- Selected elements will be highlighted with a purple color.
- Use Esc to deselect grid elements.
Copy/Paste
Selected elements (highlighted purple) can be copied and pasted either using the icon from the toolbar or using Ctrl / Cmd + C and Ctrl / Cmd + V .
Pasted elements will receive a new unique ID.
Delete
Selected elements (highlighted purple) can be deleted using the icon from the toolbar or using Delete button on your keyboard. You can also delete the element currently visible in the grid element inspector on the right side.
Scale
If your buses are too far or close to each other, use the and icons to inflate or deflate your grid. This will move your grid elements closer to or further away from each other.
Discard
Unsaved changes can be discarded by clicking on next to the button and then clicking on .
Library Component
Electrical parameters of the following electrical components can be overwritten by pre-defined models from the Component Library:
- Lines
- Transformers
- Fuses: Fuse Model
- Loads: Reactive Power, Time Series Behavior
- Generators: Reactive Power, Time Series Behavior
- Storage: Active Power
To change the electrical parameters of a line, click on the line and then in the Library Component section of the grid inspector on the right. Select the desired model from the dropdown list.
To change the reactive power characteristic of a load or generator, select the load/generator and then click on the Reactive Load/Reactive Generator in the grid inspector on the right. Under Library Characteristic the characteristic can be chosen from the dropdown list.
Grid Reconfiguration
Facilitates moving an electrically disconnected part of the grid to another grid. Click the icon in the toolbar to start the reconfiguration process. Once in the reconfiguration mode, open switches or connectors, and you will see the deenergized parts of the grid in different colors. Click the button in the part you want to move. A dialog window will open, prompting you to select the grid you want to move the grid elements in the selected part to. When the reconfiguration has completed, you will get the option to open the target grid. The elements that have been moved will be highlighted (selected). In the schematic view, you will be able to move them directly to a more convenient location if needed.
TIP
We recommend to create a grid reconfiguration as part of a grid upgrade.
