Investigation into characteristics of both wind energy resource and wind turbines in Urumqi region
摘要
Abstract
In order to evaluate the characteristics of both wind energy resource at different altitudes and wind turbines in Urumqi region,the wind speed distribution of two-parameter Weibull,variation of wind speed with altitude,wind power density and capacity factor of wind farm are analyzed.Based on the wind speed data at 10,20,30,40,50,60 and 70 m altitudes in that region,the monthly and an-nual mean wind speeds,annual mean wind power density and probability distribution of wind speed are calculated in a typical meteorological year.Besides,the shape factor,scale factor and cumulative probability of the Weibull distribution at various altitudes are estimated by making use of the maximum likelihood method.Furthermore,eight kinds of small- and medium-sized wind turbines are chosen to study their capacity factor and mean power output.As a result,it is shown that the wind energy re-source in that region is in between available and rich zones,and the capacity factor for the selected wind turbines is quite small,ranged from 4.4%to 19.8%.This is mainly attributed to the lower mean wind speed in the region.Thus the region is unsuitable for a large-scale wind farm,but small-scale wind farms or wind-hybrid power systems or mechanical systems driven by wind power can be a suitable option.关键词
