Abstract

Abstract: Most of the wind farms in Guizhou are located in the mountainous areas of high altitude and high air humidity. The air density is deduced and calculated considering the altitude and humidity. It is found that the above two factors are inversely proportional with the air density. At present, the air in the mountainous area is usually considered to be dry in wind power calculation and the effects of humidity are ignored. With the same wind turbine and wind speed, the output power is proportionally reduced with the air density. Therefore, the humidity should be considered in wind power unit design, generation estimation, power prediction.

Key words: plateau mountainous area, altitude, humidity, air density, wind power
