Scope

IEC 61400-25 focuses on the general requirements for communication between various components (such as wind turbines) and participants (such as SCADA systems) in wind farms. The internal communication of each part of the wind farm itself is not within the scope of application.
IEC 61400-25 designs a communication environment supported by the client-server model, defines the following three aspects, and models them separately to ensure the scalability of the implementation:
a) Wind farm information model;
b) Information exchange model;
c) Mapping of the information model and information exchange model to standard communication protocols.
The wind farm information model and information exchange model constitute an interface between the client and the server. As an interpretation framework for accessing wind farm data, the wind farm information model provides unified, component-oriented wind farm data to the client via the server. The information exchange model reflects all the effective functions of the server. IEC 61400-25 enables connectivity between different clients and servers from different manufacturers and suppliers for access.
As shown in Figure 1, the server defined by IEC 61400-25 includes the following aspects:
—— Information provided by wind farm components, such as "wind turbine rotational speed" or "total power generation within a certain period of time", which are modeled and can be effectively accessed;
—— The exchange service of modeled information values, defined in the GB/T 30966.3 information exchange model;
—— Mapping to communication protocols, providing a protocol stack to obtain exchange values from modeled information (GB/T 30966.4).
IEC 61400-25 only defines how to model information, exchange information, and map to specific communication protocols, and does not include how and where to implement communication interfaces, application programming interfaces, and implementation sugges
