Description

The cardinality of PowerElectronicsConnection<->PowerElectronicsUnit is 1:0..* for the canonical model, while the cardinality is 1:0..1 at the profile level.

Proposed Solution

Solution is to:

- In the 301 for the UML change the cardinality from 1..1 to 0..1 on the PowerElectronicsConnection role end.
- In the 452 EQ profile change the direction of the association
- In the 452 EQ profile change the cardinality on the PowerElectronicsUnit role end to 0..*

Decision

Call 18 Oct 2023
it is not clear why we have the many side at the PowerElectronicsUnit. This does not match the pattern we have between GeneratingUnit and RotatingMachine. This will need follow up discussion.

14-Feb-2024 discussed further during the WG13 weekly call:

- In the 301 for the UML change the cardinality from 1..1 to 0..1 on the *PowerElectronicsConnection* role end.
- In the 452 EQ profile change the direction of the association
- In the 452 EQ profile change the cardinality on the *PowerElectronicsUnit* role end to 0..*
