摘　　要：利用RegCM3区域气候模式模拟了江苏省不同离地高度的风能密度,分析了在电网用电高峰期(调峰期)的风能密度的分布特征。分析表明:陆地上调峰期的风能密度明显大于平均密度,近海海面上差异则不如陆地;夏季陆地调峰期的优势明显大于冬季。在选择风力电场位置时,若仅考虑风能资源总量,江苏省近海海面有明显的优势,但若加上并网发电的效率因素,考虑日用电高峰期的风能输出功率,则苏南(太湖附近)与沿海海面具有相近的开发潜力。By using regional climate model the wind energy density of Jiangsu Province was simulated and the distributing character of wind energy density during electric power peak period was analyzed. On land the wind energy density during electric power peak period is more than average wind energy density especially in summer, but on the offshore sea this kind of increase is quite inconspicuous. If only gross wind energy is considered, offshore sea has obvious superiority, but if taking into account wind energy density during electric power peak period, south of Jiangsu and offshore sea have similar exploitation potential.
