Design and Realization of the Supervisory Information System for Wind Plant Based on the OPC Technology

With the rapid development of wind power technology, the single SCADA system can not meet the needs of wind farms. In view of the problems that different SCADA system is not compatible and data is not be shared, the paper analyzes and designs the supervisory information system(SIS) for wind farm based on OPC technology. The technology of OPC solves the problem of communication between different equipments, and this system using OPC has realized the following functions: unified management of data for multi-wind farms, performance calculation and analysis and so on, and provided an information platform for modern management of enterprises.
