摘要: 贵州大部分风电场处于海拔高、空气湿度大的山区,通过对计及海拔、湿度的空气密度进行推导、计算,发现这2个因素都与空气密度成反比,且目前风电场在计算中通常将山区空气按照干空气进行计算,未考虑湿度的影响。同一型风机在相同风速的情况下,其输出功率与空气密度等比例降低,因此,在机组选型、发电量估算,风功率预测等方面应加以考虑。

关键词: 高原山区, 海拔, 湿度, 空气密度, 风电功率

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
