A wind energy conversion system was assembled with a small-scale wind driven generator (Yamada type) of rated output 1 KW, storage batteries of 24V×600AH and fluorescent lamps. This system was operated for 333 days for the period Aug. 1982 to July 1983. In the average of daily energies, the wind energy of 13.1KWH was inputted to the cross section (11.34m^2) of rotating blades, 1.07KWH of which was converted to electric energy and 0.89KWH was used for the lighting. The relation between mechanical efficiency and wind characteristics was discussed. The mean generation efficiency and the mean transfer efficiency of the energy throughout the system were evaluated as 8.2% and 6.8%, respectively. From these further problems were discussed.
