CIM Issues #5098
CsConverter targtAlpha and targetGamma
61970-301, 61970-452, 61970-600
Description
The description of CsConverter.targetAlpha contains the constraint " It is only applicable for rectifier if continuous tap changer control is used."
The description of CsConverter.targetGamma contains the constraint " It is only applicable for inverter if continuous tap changer control is used."
The following needs to be clarified:
- on what element is the tap changer e.g. is it the TapChangerControl that regulates the Terminal that is referenced by ACDCConverter.PccTerminal or it is something else?
- the severity shall be clarified - to confirm that this is error if these conditions are not met
Proposed Solution
The description of CsConverter.targetAlpha currently contains the constraint: "It is only applicable for rectifier if continuous tap changer control is used."
The description of CsConverter.targetGamma currently contains the constraint: "It is only applicable for inverter if continuous tap changer control is used."
In the 301 we change the above respectively to:
"It is only applicable for rectifier control."
and
"It is only applicable for inverter control."
(it is also suggested that we include the below clarification on the control modes within the description in the 301 as well)
In the 456 (and 600 to reference it) we to verify and/or update if necessary:
The two control modes are mutually exclusive therefore it is expected that one, and only on, will be specified in the SSH profile (this must be verified that a constraint already exists today in the 456 for SSH that enforces this).
The SV attributes alpha and gamma for CsConverter are currently both required cardinality. They should both be optional and a constraint added to link them to the type of control declared within SSH. Only one or the other should be present but not both.
Decision
Apply the above proposed solution as amendments to the publication for CIM17. They should naturally be carried over and appear within CIM18 publications as well.
May want to evaluate at the same time if we have other minor "bug fixes" we may want to include at the same time.
Chavdar: To work with ENTSO-E to determine impact and how they will approach this.

02-May-2023:
The SV attributes alpha and gamma for CsConverter are currently both required cardinality. They should both be optional and a constraint added to link them to the type of control declared within SSH. Needs to be discussed. Only one or the other should be present but not both.
Important open question/action items:
What do we do with the current release of the 456/600 standards (CIM17) and the 301 for the description that should be clarified? Needed in the short term for ENTSO-E that can not wait until CIM18.
