Abstract
An integrated system of micro windmill has been developed for use in our life setting. The performance of the windmill was tested and especially, its characteristics were studied by PIV technique. The diameter of micro wind turbine is 500 mm. This micro wind turbine is a unit of integrated wind energy system. The micro turbine has features as large solidity and long chord length. The measurement was carried out with 3×1.8m^2 wind tunnel at the wind speed in the range from 3 to 10m/sec. Twin YAG laser was employed to the measurement.
