To obtain the feasibility result of wind farm in our country, first of all, the detailed survey of wind energy on Cheju Province which is known as the area of abundant wind energy, but more electricity supply is needed because of rapidly increasing electricity consumption, was carried out. The contents of this report are summarized as follows; - Survey of wind energy utilization and wind energy analysis technique - Analysis of wind energy characteristics in Cheju Province - Development of wind energy analysis program This program provides 13 summarized analysis result and 34 detailed analysis result. And for the convenient understanding of wind energy characteristics, the graphic program was developed which enables to display the graph drawing in the monitor. (author). refs., figs., tabs.
