Abstract：Aiming at the existing problem of current wind farm supervisory control and data acquisition（SCADA）system，such as the weak data access flexibility and consolidation，data integrity is vulnerable to networks and environmental factors，also through the investigation and analysis of new requirements like wind farm integrated management and multimedia monitoring，the wind farm SCADA system and data structure were studied and designed，and a solution of Web-based wind farm SCADA and information management

system was introduced. Key technologies of this system was described in details，such as architecture of system hardware and software， turbine data model set up，breakpoint continuingly support of data transmission，distributed computation and multimedia access. A test on functions of the system was carried out through the field deployment and use of the system in a wind farm. The results indicate that，the system is able to access data of wind turbine and electric equipment from different manufacturers，data continuity and integrity guarantee

is improved significantly，the application of multimedia technology increase the diversity of the real time monitoring，integrated management help users promote maintenance and management performance. The successful development and use of the system has positive reference value for the development of wind farm monitoring and management technology.
