Using the Foreign Key in PowerFactory , consider the following aspects:

- You can have differences between object name and foreign key name, for example:
object name = "West Cable 24"; foreign key name = "FKEY-West Cable 24"

- The Foreign key names should not have more than 40 characters. If the SCADA name
of a load is e.g. L1234 then the foreign key can also be L1234.
This can simplify the interface because it is easy to implement a 1:1 link, i.e. each object
in SCADA corresponds to one object in DIgSILENT PowerFactory. The foreign key is called foreign,
because it is a key from another system (e.g. SCADA).

- Foreign keys are case sensitive, so the following two lines do not refer to the same object
(hint: also object names are also case sensitive).
1. fk_breaker
2. fk_Breaker
• Foreign keys must be unique within a project, but names could be the same,
if these are stored in different data folders in the PowerFactory database.
