Abstract:
Based on the 30year wind data of basic observation stations from 1971 to 2000 and the wind data of automatic weather stations from 2006 to 2009 in Dalian, the wind speed, valid hours, mean wind power density, and effective wind power density are computed, and the spatial characteristics of wind power in Dalian are analyzed. The results show that the wind power resources are very abundant in Dalian, and the annual effective wind power density is greater than 80 W/m2 in most areas of Dalian, Lushun Station having the highest value of 191.7 W/m2; the values of Changhai, Dalian and Wafangdian are above 150 W/m2. The effective wind power density of Jinzhou is 104.2 W/m2, Zhuanghe and Pulandian less than 100 W/m2. Valid hours for most areas are above 4500 hours per year, above 6500 hours per year for Dalian and Changhai, and between 4800 and 5500 hours per year for Lushun, Wafangdian, and Changhai. The wind power resources in Dalian have the following spatial distribution features: more abundant in the coast and island areas than in the inland areas, in the south parts than in the north parts, and in the western coast than eastern coast.
