| 摘 要： | 利用西北地区和东南沿海地区具有代表性的测风塔资料,对比分析其风能资源特性差异,结果发现:①即使西北和东南沿海地区的年平均风速相同,西北地区的年平均风功率密度和年风能密度均显著大于东南沿海地区,其风功率密度可大1～2个等级,造成这种显著差异的关键因子是西北地区"大风速"的出现频率较东南沿海地区多;②西北地区和东南沿海地区的风向变化主要以小角度变化为主,但两地区的风向变化特征明显不同:西北地区的小风向变差角出现频率略少于东南沿海地区,而较大的风向变差角出现频率明显多于东南沿海地区.两类地区不同的风资源特性将影响风电场选址和设计、风电机组选型以及建成后的运行管理模式,具有重要的现实意义和使用价值. |
| 关 键 词： | 风能资源 风速和风向特性 典型地区 |

| Abstract: | Northwest China and southeast coast of China are the two typical areas which are affluent in wind-energy resources in our country.A comparative study was carried out on characteristics of wind-energy resources by analyzing the observational data obtained from towers which are representative in the two areas.The results showed that even if the annual mean wind speed in the northwest China is the same as that in the southeast coast of China,the annual mean wind power density and the annual wind energy density... |
| Keywords: | wind-energy resource characteristics of wind speed and direction typical area |
