In the following Master’s degree research main information and communication aspects in wind power plant farm analyzed and demonstrated by constructing basic prototype. The wind energy market in Europe is growing and needs have arisen to develop standard-based information systems to support future expansion of wind energy in Lithuania. Introduction and first chapter overview the background for modeling such system. Requirements for data structures representing main measurements and information exchange inside and outside of the system are defined on the base of IEC 61400-25 standard “Wind Turbine Generator Systems - Part 25: Communications for monitoring and control of wind power plants”. Models, comprising such system are described and possible communication topologies enumerated. From several existing communication profiles, defined in above mentioned standard, SOAP / XML based web services for communication architecture are chosen and prototype built. Article based on this work was written together with coauthor professor A. Nemura and presented in international KTU conference “Automation and Control technologies – 2005���� and LEI conference “Application of information and management technologies in electricity energetics“. The purpose of article is to form and refine the wind farm information system problem introducing IEC 61400-25 standard.
