Description

There is a need to specify point of connection for the wind plant
the RemoteInputSignal can be used to define the point of common connection of the wind plant (park) is, using the RemoteInputSignal.Terminal reference for this purpose.
The problem is that the WindPlantDynamics.RemoteInputSignal association is of cardinality [0..1], which is not appropriate for this purpose. The cardinality should be [1..1].
The point of common connection is essential for the wind plant control model and the simulation algorithm.

This is prescribed in IEC 61400-27-1:2020

Proposed Solution

Another association could be added

Decision

Apply the proposal following IEC 61400-27-1:2020.It is prefered to add required association between WindPlantDynamics and Terminal in order not to confuse with other meaning of RemoteInputSignal.

Release Notes

The following changes are applied to 302 and 457:
- add required association WindPlantDynamics.PointOfConnection between WindPlantDynamics and Termnal
