IEC 61400-25 Part 2 and Part 3 CDV approved

The following two documents (CDV – Committee Drafts for Vote) have been accepted by 100 per cent of the Members of IEC TC 88 (in August resp. in September 2014):

Wind turbines – Part 25-2 (Edition 2): Communications for monitoring and control of wind power plants – Information models

Wind turbines - Part 25-3 (Edition 2): Communications for monitoring and control of wind power plants -Information exchange models

Both parts will be published as FDIS soon.

The Information Models are revised to make them consistent with the many other models defined in IEC 61850-7-x. For example in LN WTUR several names of DataObjects change:

SptDmdW to DmdWSpt
SptDmdVAr to DmdVArSpt
SptDmdPF to DmdPFSpt

The Edition 2 of the models is a major step towards harmonization of the information models. The wind power plant objects are now very stable – they are also incorporated into the UML master maintained by IEC TC 57 WG10, WG 17, WG 18, and JWG25 (TC57/TC88):

The changes proposed in conjunction of the CDV comments on part 25-2 have already been used for the UML model. Now we have a very stable and harmonized set of information models that can be used for the whole power delivery system – all over.

Additional models are under way, e.g., for condition monitoring (90-3).

Thanks to the UML team!
