19、 61400-25 series addresses vendors (manufacturers, suppliers), operators, owners, planners, and designers of wind power plants as well as system integrators and utility companies operating in the wind energy market. The IEC 61400-25 series is intended to be accepted and to be used world-wide as the
20、international standard for communications in the domain of wind power plants.The IEC 61400-25 series has been developed in order to provide a uniform communications basis for the monitoring and control of wind power plants. It defines wind power plant specific information, the mechanisms for informa
21、tion exchange and the mapping to communication protocols. In this regard, the IEC 61400-25 series defines details required to exchange the available information with wind power plant components in a manufacturer-independent environment. This is done by definitions made in this part of the IEC 61400-
22、25 series or by reference to other standards.The wind power plant specific information describes the crucial and common process and configuration information. The information is hierarchically structured and covers for example common information found in the rotor, generator, converter, grid connect
23、ion and the like. The information may be simple data (including timestamp and quality) and configuration values or more comprehensive attributes and descriptive information, for example engineering unit, scale, description, reference, statistical or historical information. All information of a wind
24、power plant defined in the IEC 61400-25 series is name tagged. A concise meaning of each data is given. The standardised wind power plant information can be extended by means of a name space extension rule. All data, attributes and descriptive information can be exchanged by corresponding services.T
25、he implementation of the IEC 61400-25 series allows SCADA systems (supervisory control and data acquisition) to communicate with wind turbines from multiple vendors. The standardised self-description (contained either in a XML file or retrieved online from a device) can be used to configure SCADA ap
26、plications. Standardisation of SCADA applications are excluded in the IEC 61400-25 series but standardised common wind turbine information provides means for re-use of applications and operator screens for wind turbines from different vendors. From a utility perspective unified definitions of common
27、 data minimise conversion and re-calculation of data values for evaluation and comparison of all their wind power plants.The IEC 61400-25 series can be applied to any wind power plant operation concept, i.e. both individual wind turbines, clusters and more integrated groups of wind turbines. The app
28、lication area of the IEC 61400-25 series covers components required for the operation of wind power plants, i.e. not only the wind turbine generator, but also the meteorological system, the electrical system, and the wind power plant management system. The wind power plant specific information in th
29、e IEC 61400-25 series excludes information associated with feeders and substations. Substation communication is covered within the IEC 61850 series of standards.The intention of the IEC 61400-25 series is to enable components from different vendors to communicate with other components, at any locati
30、on. Object-oriented data structures can make the engineering and handling of large amounts of information provided by wind power plants less time-consuming and more efficient. The IEC 61400-25 series supports scalability, connectivity, and interoperability.The IEC 61400-25 series is a basis for simp
31、lifying the contracting of the roles the wind turbine and SCADA systems have to play. The crucial part of the wind power plant information, the information exchange methods, and the communication stacks are standardised. They build a basis to which procurement specifications and contracts could easi
32、ly refer.The IEC 61400-25 series is organised in several parts. IEC 61400-25-1 offers an introductory orientation, crucial requirements, and a modelling guide.NOTE 1 Performance of the IEC 61400-25 series implementations are application specific. The IEC 61400-25 series does not guarantee a certain
33、level of performance. This is beyond the scope of the IEC 61400-25 series. However, there is no underlying limitation in the communications technology to prevent high speed application (millisecond level responses).NOTE 2 IEC 61400-25-4 is, at the time of the publication of IEC 61400-25-1 (this part
34、), still to be published. W ith IEC 61400-25-4 the mapping of the information and information exchange models to a specific communication profile will be described/defined in detail. IEC 61400-25-4 may consist of more than one normative mapping but at least one of the optional mappings has to be sel
35、ected in order to be in conformance with the IEC 61400-25 series. IEC 61400-25-4 is expected to include the following mappings:W ebservicesIEC 61850-8-1 MMS OPC XML DAIEC 60870-5-104DNP3Each of the different mappings specifies individually which and how information models (IEC 61400-25-2) and inform
36、ation exchange models (IEC 61400-25-3) will be supported. The mapping will only reflect the information model and the information exchange services given in IEC 61400-25-2 and IEC 61400-25-3. The individual selected mapping will as a minimum support the mandatory data and data attributes, and the associated services. A specific mapping may, for implementation reasons or due to underlying properties of the communication protocol used,
