The focus of the IEC 61400-25 series is on the communications between wind power plant
components such as wind turbines and actors such as SCADA Systems. Internal
communication within wind power plant components is outside the scope of the IEC 61400-25
series.
The IEC 61400-25 series is designed for a communication environment supported by a clientserver
model. Three areas are defined, that are modelled separately to ensure the scalability
of implementations:
1) wind power plant information models,
2) information exchange model, and
3) mapping of these two models to a standard communication profile.
The wind power plant information model and the information exchange model, viewed
together, constitute an interface between client and server. In this conjunction, the wind
power plant information model serves as an interpretation frame for accessible wind power
plant data. The wind power plant information model is used by the server to offer the client a
uniform, component-oriented view of the wind power plant data. The information exchange
model reflects the whole active functionality of the server. The IEC 61400-25 series enables
connectivity between a heterogeneous combination of client and servers from different
manufacturers and suppliers.
