【摘要】：論文詳細(xì)分析了中國(guó)北方地區(qū)風(fēng)電發(fā)展及分布現(xiàn)狀和京津冀地區(qū)霧霾污染現(xiàn)狀:目前中國(guó)北方地區(qū)大規(guī)模發(fā)展風(fēng)電,內(nèi)蒙古自治區(qū)和河北省風(fēng)電裝機(jī)總量在全國(guó)數(shù)一數(shù)二,主要分布在內(nèi)蒙古中東部和河北省北部地區(qū),上述地理位置是京津冀地區(qū)的上風(fēng)口,且西北上空的清潔空氣團(tuán)對(duì)京津冀地區(qū)的霧霾具有有效的清除作用。北方大規(guī)模風(fēng)電在發(fā)電過(guò)程中,風(fēng)通過(guò)內(nèi)蒙古、張家口、承德等地風(fēng)電時(shí)部分風(fēng)能被消耗,致使到達(dá)下風(fēng)向區(qū)位的京津冀風(fēng)能減少,且由于風(fēng)能與風(fēng)速的三次方成正比,這可能導(dǎo)致京津冀地區(qū)風(fēng)速減小,又因?yàn)閬?lái)自北方的大風(fēng)對(duì)本地區(qū)霧霾有重要的清除作用,因此可能加劇霧霾。本文以保定地區(qū)為例,收集氣象數(shù)據(jù)和風(fēng)電數(shù)據(jù),采用圖表法和數(shù)據(jù)分析法對(duì)北方大規(guī)模風(fēng)電對(duì)京津冀地區(qū)風(fēng)速的相關(guān)性以及對(duì)京津冀地區(qū)霧霾影響等展開研究。經(jīng)計(jì)算能見度(代表霧霾嚴(yán)重程度)與日平均風(fēng)速為低度正相關(guān),年平均風(fēng)速與北方風(fēng)電并網(wǎng)裝機(jī)容量(代表風(fēng)電消耗風(fēng)能的量)均為中度正相關(guān),最后得出,北方風(fēng)電并網(wǎng)裝機(jī)容量與能見度的相關(guān)性系數(shù)為0.287,雖然呈正相關(guān),由于相關(guān)性系數(shù)小于0.3,屬于基本無(wú)相關(guān)性。其中,北方大規(guī)模風(fēng)電對(duì)京津冀地區(qū)風(fēng)速的相關(guān)性研究與理論推導(dǎo)存在差異,進(jìn)一步分析原因得出最終本文結(jié)論:到目前為止,北方大規(guī)模風(fēng)電發(fā)展對(duì)京津冀地區(qū)風(fēng)速基本無(wú)影響,進(jìn)而對(duì)于京津冀地區(qū)霧霾的影響甚弱。
[Abstract]:The paper analyzes the development and distribution of wind power in northern China and the present situation of smog pollution in Beijing-Tianjin-Hebei region: at present, the total amount of wind power installed in Inner Mongolia Autonomous region and Hebei Province is one of the highest in China. The above location is the upper tuyere in the Beijing-Tianjin-Hebei region, and the clean air mass over the northwest has an effective effect on the smog removal in the Beijing-Tianjin-Hebei region. In the process of large-scale wind power generation in the north, some wind energy is consumed when wind power passes through Inner Mongolia, Zhangjiakou, Chengde and other places, resulting in a decrease in the wind energy from Beijing, Tianjin and Hebei to the lower wind direction, and because wind energy is directly proportional to the third power of the wind speed. This could lead to a decrease in wind speeds in the Beijing-Tianjin-Hebei region, which could be exacerbated by the fact that strong winds from the north have an important role in clearing the smog in the region. Taking Baoding area as an example, meteorological data and wind power data are collected, and the correlation of large-scale wind power in northern China to wind speed in Beijing-Tianjin-Hebei region and the influence of smog on smog in Beijing-Tianjin-Hebei region are studied by using chart method and data analysis method. The calculated visibility (representing the severity of smog) is positively correlated with the daily average wind speed, and the annual average wind speed is moderately correlated with the installed capacity of wind power grid connected to the north (representing the amount of wind energy consumed by wind power). The correlation coefficient between the installed capacity of wind power grid and visibility is 0.287, although it is positively correlated, because the correlation coefficient is less than 0.3, it belongs to the basic no correlation. Among them, there are differences between the correlation study and theoretical deduction of wind speed in Beijing-Tianjin-Hebei region by large-scale wind power in northern China. The final conclusion of this paper is obtained by further analyzing the reasons: so far, The development of large-scale wind power in northern China has little effect on the wind speed in Beijing-Tianjin-Hebei area, and then has a weak effect on smog in Beijing-Tianjin-Hebei area.
