IEC
61400-25 (Communications for monitoring and control of wind power plants, TC 88) provides uniform information exchange for monitoring and control of wind power plants. This addresses the issue of proprietary communication systems utilizing a wide variety of protocols, labels, semantics, etc., thus enabling one to exchange information with different wind power plants independently of a vendor. It is a subset of IEC 61400
; a set of standards for designing wind turbines.
The IEC 61400-25 standard is a basis for simplifying the roles that the wind turbine
and SCADA
systems have to play. The crucial part of the wind power plant information, information exchange methods, and communication stacks are standardized. They build a basis to which procurement specifications and contracts could easily refer.
The standard has specified five mapping (IEC 61400-25-4) to communication protocol stacks in order to address the real wind power business needs for communication. The mappings specified in the part of IEC 61400-25 comprises a mapping to SOAP

Wind turbine
A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator or wind charger. If the mechanical energy is used to drive machinery, such as for grinding grain or...
