Title: Research on the Characteristics of Wind Energy Resources over Huangang Wind Farm in Jiangsu Province
Abstract: Based on the analysis of wind data measured at one wind measurement tower over Huangang Wind Farm in Jiangsu Province from Dec. 2010 to Nov. 2011, it was calculated that at 10, 50, 70 and 80 m heights the annual average wind speed was 4.0 6.1 m/s, the annual average wind power density was 80.4 238.4 W/m2, the annual effective wind power density was 116.5 262.5 W/m2, the annual effective hours were 5777 7845 h, and the annual effective wind energy density was 679.3 2041.5(kW·h)/m2. In addition, the dominant wind directions were NNE, N and NE, the sum of them took up nearly 30% of the full year wind directions, the wind energy density of the dominant wind directions accounted for almost 50% of the full year wind energy density, and the wind speed was mainly ranging from 3 to 8 m/s, about 80% of the full year wind speeds. Overall, wind energy resource was abundant in this region. Especially the hub height of the already built wind turbines had the wind power density of more than 250 W/m2, and the effective hours took up nearly 90% of the full year. Therefore, wind energy resource had a great value of development and utilization in this region.
