風速資料 分析에 의한 風力發電시스템 最適 設計
摘要
In this paper, how to design the wind power generation system is presented. It is shown that the wind system optimization can be achieved by consideration of the four factors; wind statistics, efficiency of conversion of wind energy to electrical energy, average annual energy extracted and load factor. The wind is characterized by a weibull probability function. The Weibull parameter is calculated for the characterizing wind and the primary design specification of ten different sites. Some graphs are presented, which can be used to design a wind system for maximum output of a specified load factor at given site. Two different systems, V_c = 0.4 V_R and V_c = 0.5V_R are discussed, as samples, for investigation of the effects on the system through the variation of cut-in speed.
