【 摘 要 】

Nowadays, wind power generators have been developed widely in China and cover a wide range of larger humidity areas such as the southern of china, mountains and coastal. However, wind farm's output calculation has never taken regional air humidity into account at present, which regional air is considered as dry's one. By theoretical analysis and case calculation, this paper presents air density is inversely proportional to air humidity, which makes wind power be proportional to air density under the same wind velocity and wind power generator. As a result, regional air humidity should be considered in many factors such as unit selection, estimation of unit's output and wind power prediction.
