Initial situation

Strands can be used to graphically represent the power supply of a network. Using the functions "Verify", "Update" and "Recreate", which are available in the attribute editor of the electrical objects, these strands can be created and updated efficiently.

Procedure

Create new strand

Scenario: Create new strand, e.g. for a newly created area.

Process:

1. Open the attribute editor for one of the new electrical objects (cable, house connection, ...).
2. Check the topology with the "Verify" button.
3. Creating the strand for the objects found in step 2 via "Update".

In summary: with one click, the "Update" function creates a new strand and links it to all topologically connected electrical objects.

Extending an existing strand

Scenario: An existing network with strand is extended by capturing new electrical objects.

Process:

1. Opening the attribute editor for one of the new objects.
2. Checking the topology with the "Verify" button.
3. Updating the information about the strands with the "Update" button.

In summary: in this case, the "Update" function updates the reference to the strand for all topologically connected electrical objects with one click. Since there is already a referenced strand in this subnet, it will be propagated to all electrical objects that do not yet have a strand reference.

Resolve a conflict when updating strands

Scenario: Running the "Update" function (or the "Create or Update Strand" validation) causes conflicts (errors in the GEONIS log). There are two ways to resolve these conflicts:

(a) Using the "Update" function to keep a strand. For this case, one of the two strands must be deleted beforehand (from the attribute editor of the respective strand).

Process:

1. Opening the attribute editor (from the GEONIS log) for the strands causing the conflict.
2. Identify whether the conflict is due to a topology error or not.
   • Correct the geometry and topology of the electrical objects if necessary.
   • If the topology is correct, decide which strand to keep.
3. Open the attribute editor for the strand that should be deleted. Delete this strand from the attribute editor.
4. Open the attribute editor for one of the electrical objects and execute the "Update" function. The remaining strand will then be referenced with all topologically connected elements.

b) Both existing strands are ignored and using the "Recreate" function, a new strand is created and referenced with the objects.

Process:

1. Open the attribute editor (from the GEONIS log) for the strands causing the conflict.
2. Identify if the conflict is due to a topology error or not (correct the geometry and topology of the electrical objects if necessary).
3. Once the topology is correct, open the attribute editor for a cable and create a new strand using the "Recreate" function.
4. A new strand will be created in the database and referenced at all topologically connected elements. All existing strand references will be overwritten.

It is important to check the topology using the "Verify" button before creating a new strand. This avoids transferring strand references to elements that may be incorrectly connected.

In summary: With just a few clicks, the user can correct conflicts during strand creation. The user can choose to keep one of the strands or create a new strand and overwrite all existing references.

Note: After using the "Recreate" function, the "Delete Unreferenced Strand" validation should occasionally be run under Electrical Supply > Strands > Update Strands to delete unreferenced strands. All strands that are not referenced on at least one electrical object in the database will be deleted.

Updating strands when a change is made to the power supply

Scenario: A change is made to the power supply in an area. For example, a new station is built and part of the existing cables are supplied from this new station. It is thus necessary to create a new strand for the elements that will be disconnected from the current strand, so as not to have the same strand twice in separate parts of the power network.

Process (after the network has been adjusted) :

1. For the part of the network whose power supply does not change, the "Update" function can be used.
2. For the part of the network that is being resupplied, the strand reference can be overwritten using the "Recreate" function.

In summary: The "Recreate" function allows you to create a new strand in one action and assign it to the topologically connected elements.
