Based on the successful application of substation configuration language(SCL) and the characteristics of wind farms,a IEC 61400-25 standard wind power plant configuration tool is designed using extensible markup language(XML), information model in IEC 61400-25 and database. The configuration tool includes modules of configuration interface, XML parser, transformation between tree controls and wind power plant configuration language(WPPCL) document, WPPCL document generation and data storage. A method is proposed for transmitting standard configuration files among involved equipments to implement uniform configuration of wind power plants.
