IEC 61400-25 (all parts) focuses on the general requirements for communication between components in a wind farm (eg wind turbines) and participants (eg SCADA systems). The internal communication of each part of the wind farm itself is not within the scope of application. IEC 61400-25 (all parts) designed the communication environment supported by the client-server model, defined the following three aspects, and modeled them separately to ensure the scalability of the realization: 1) wind farm information model; 2) Information exchange model; 3) The information model and the information exchange model are mapped to the standard communication protocol. The wind farm information model and information exchange model constitute an interface between the client and server. As an interpretation framework for accessing wind farm data, the wind farm information model provides unified, component-based wind farm data to clients through servers. The information exchange model reflects the full functionality of the server. IEC 61400-25 (all parts) enables commonality of access between different clients and servers from different manufacturers and suppliers. As shown in Figure 1, the server defined by IEC 61400-25 (all parts) includes the following aspects: --Information provided by wind farm components, such as "wind turbine rotor speed" or "total power generation”, this information is modeled and can be effectively accessed. Modeled information is defined in GB/T 30966.2 Information Model. -- Exchange services for modeled information values, defined in this part of the information exchange model. -- Mapped to the communication protocol, providing a protocol stack to obtain the exchange value from the modeled information (GB/T 30966.4). IEC 61400-25 (all parts) 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 program interfaces, and implementation recommendations. However, the purpose of IEC 61400-25 (all parts) is to obtain information related to a single wind farm component (such as a wind turbine) through the corresponding logic device. This part of GB/T 30966 specifies the abstract communication service interface describing information exchange between client and server: --data access and acquisition; --device control; --event reporting and recording; --publisher and subscriber ; -- self-description of the device (device data dictionary); -- data type and data type discovery.
