SetRef: Setting for indicating an IEC 61850 object reference. Some function need to have a setting indicating which input (for example SV streams, phasors, CB position…) has to be used. There is no setting DO defined in existing LN, it is proposed to add this DO in LN GAPC to make it generic. More details on use cases (see attached documents): * Use case 1: recloser function where it is necessary to use the line voltage and busbar voltage. The busbar voltage to be used depends on the topology of the substation. This means that an external function needs to indicate which voltage busbar is to be used. The SetRef is written by the external function and corresponds to the TVTR stream of the relevant merging unit. It cannot be done by configuration as the topology changes dynamically depending on the state of circuit breaker and disconnector switches. * Use case 2: in case of redundant SV streams, several merging unit may be eligible to provide the SV stream use for the function. Since the opening of the issue, RTE has chosen to use InRef and dynamically write the SrcCBRef (with an external function) to cover these use cases. No other uses cases that could not be covered this way have been identified. There is no longer need to have implementation of SetRef. [New parametres need to be modelled in GAPC LN. This issue refer to SetRef parameters, as explained in the attached documents by RTE.]
