CGMES: SynchronousCondensers are not imported

[jeandemanged]

Describe the current behavior

cim:SynchronousMachine-s with type SynchronousMachineKind.condenser are not imported in iIDM

Describe the expected behavior

Synchronous condensers should be imported in iIDM

Describe the steps

• Load a CGMES with a cim:SynchronousMachine with type SynchronousMachineKind.condenser. As per QoCDC rule SynchronousCondenser (line 2626), the SynchronousMachine should not have any cim:GeneratingUnit associated.
• check iIDM content, the condenser cannot be found

Environment

powsybl-core:5.2.1

Relevant Log Output

No response

Extra Information

It seems that the SPARQL query for synchronous machines assumes that a GeneratingUnit is always present for SynchronousMachines, but this isn't true for condensers - hence query is missing the condensers. cim:RotatingMachine.GeneratingUnit should be considered optional in query, or another dedicated query should be made for condensers.

[zamarrenolm]

I think it will be clearer if we make a specific separate query for synchronous machines than can only be "condensers". For the rest of types (generator, motor and its combinations) we should always have an associated generating unit.
