In view of the problem of the Remote Supervisory Control System of wind turbines, we design a solution based on the mobile Internet technology and implement it. The mobile client based on the Android operating system for the mobile remote supervisory control of wind turbines is developed. We create the state and fault monitoring software based on XML-DA OPC which exchanges data via Internet, resolving the problems of the interface protocols compatibility of hardware equipment and multi-platform supporting requirements. In this paper, the overall framework of the monitoring scheme is introduced, the design idea of OPC XML-DA server and mobile client is described, and the function is realized. The test results show that this system can accomplish the real-time monitoring of the wind turbines efficiently. In addition, this system can be applied in the field of smart home and various industrial control areas.
