As the power performance test for wind turbine, metrological data is important. All data like electric power data for wind turbine and metrological data are collected at the same time. Also, weather station is installed in the place where it is far 2.5times of diameter of wind turbine rotor. Generally, as to the weather data communication method in the wind turbine performance test, the fiber optic cable is used. If wind turbine test is played at offshore, a wireless communication should be considered. In this paper, we suggested a data acquisition system with wireless transmission which was used the WCDMA communication and the system was constructed. Also, for the real-time implement of Tablet PC, We used the Appspresso that is a hybrid cross platform mobile framework which wraps source code developed with web technology by each mobile platform runtime and builds them into native mobile apps. In the future at offshore wind turbine performance test, the availability of this system will be used and enhanced.
