17、s communication for monitoring and control of wind power plants. The modeling approach of the IEC 61400-25 series has been selected to provide abstract definitions of classes and services such that the specifications are independent of specific protocol stacks, implementations, and operating systems
18、. The mapping of these abstract classes and services to a specific communication profile may be found in IEC 61400-25-41.This part of IEC 61400-25 defines the methods and abstract test cases for conformance testing of devices used in wind power plants. The intended readers are test system developers
19、.NOTE 1 It is recommended to obtain a common knowledge of the standards IEC 61400-25-1, IEC 61400-25-2, IEC 61400-25-3, and IEC 61400-25-4 before reading this part.NOTE 2 Abbreviations used in IEC 61400-25-5 may be listed in Clause 3 or may be found in other parts ofIEC 61400-25 that are relevant fo
20、r conformance testing.1 To be published.WIND TURBINES Part 25-5: Communications for monitoring and control of wind power plants Conformance testing1ScopeThe 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 Sy
21、stems. 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 client- server model. Three areas are defined, that are modelled separately to ensure the scalability of
22、 implementations:1) wind power plant information models,2) information exchange model, and3) 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.
23、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 exchan
24、ge 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.As depicted in Figure 1, the IEC 61400-25 series defines a server with the following aspec
25、ts:Information provided by a wind power plant component, e. g., “wind turbine rotor speed” or “total power production of a certain time interval” is modelled and made available for access. The information modelled in the standard is defined in part IEC 61400-25-2,services to exchange values of the m
26、odelled information defined in part IEC 61400-25-3,mapping to a communication profile, providing a protocol stack to carry the exchanged values from the modelled information (part IEC 61400-25-4).The IEC 61400-25 series only defines how to model the information, information exchange and mapping to s
27、pecific communication protocols. The IEC 61400-25 series excludes a definition of how and where to implement the communication interface, the application program interface and implementation recommendations. However, the objective of the IEC61400-25 series is that the information associated with a s
28、ingle wind power plant component(such as the wind turbine) is accessible through a corresponding logical device.This part of IEC 61400-25 specifies standard techniques for testing of conformance of implementations, as well as specific measurement techniques to be applied when declaring performance p
29、arameters. The use of these techniques will enhance the ability of users to purchase systems that integrate easily, operate correctly, and support the applications as intended.NOTE The role of the test facilities for conformance testing and certifying the results are outside of the scope ofIEC 61400
