摘要:

針對(duì)目前實(shí)測(cè)數(shù)據(jù)少、地表覆蓋差異考慮不全面等問(wèn)題,本文選取了內(nèi)蒙古灰騰梁風(fēng)電基地的5所自動(dòng)氣象站,通過(guò)對(duì)比風(fēng)電場(chǎng)內(nèi)、上/下風(fēng)向與側(cè)風(fēng)向的大氣溫度和比濕差異,得到不同風(fēng)向上大氣溫度和比濕的日變化和季節(jié)變化特點(diǎn),最終判斷風(fēng)力發(fā)電機(jī)運(yùn)行對(duì)典型草原大氣溫度及比濕的影響。通過(guò)對(duì)氣象站數(shù)據(jù)的分析,發(fā)現(xiàn)風(fēng)力發(fā)電機(jī)的運(yùn)行會(huì)使得大氣出現(xiàn)明顯的"增溫"和"減濕"效應(yīng)。具體表現(xiàn)在:上風(fēng)向和下風(fēng)向"增溫"和"減濕"最為明顯,全年上風(fēng)向的平均增溫可以達(dá)到1.07℃,下風(fēng)向平均增溫可以達(dá)到1.25℃;全年上風(fēng)向比濕平均減少0.17 g·kg^-1,下風(fēng)向比濕平均減少0.16 g·kg^-1。風(fēng)電場(chǎng)的"增溫"和"減濕"幅度可能改變草地生態(tài)系統(tǒng)進(jìn)程,因此在建設(shè)風(fēng)電場(chǎng)的同時(shí),需要更好的理解風(fēng)力發(fā)電對(duì)環(huán)境的影響。

Abstract:

Due to a lack of field-measured data and incomplete consideration of variability in land surface coverage, this paper selected five automatic meteorological monitoring stations at Huitengliangwind power base in China. By comparing the variability of temperature and specific humidity inside the wind farm, and in the upwind, downwind and side wind directions, daily and seasonal variations in temperature and specific humidity were obtained. Finally, the influence of wind turbine operation on the atmospheric temperature and specific humidity of typical steppe was judged. It is found that wind turbines increase the temperature and decrease the specific humidity of the atmosphere. These effects are most obvious in the upwind and downwind directions. The annual average temperature rise was 1.07 ℃ in the upwind direction and 1.25 ℃ in the downwind direction. On average throughout the year, specific humidity decreased by 0.17 g·kg^-1 in the upwind direction and 0.16 g·kg^-1 in the downwind direction. The magnitudes of "warming" and "reducing specific humidity" of wind farms may change the grassland ecosystem process, so the better understand should be needed in the impact of wind power generation on the environment while building wind farms.
