2012-2021年吉林西部地区风速气候特征及其对风力发电的影响
Climatic characteristics of wind speed in the western region of Jilin province from 2012 to 2021 and their impact on wind power generation
摘要
Abstract
Utilizing hourly wind speed observation data from eight national meteorological stations in the western region of Jilin province from 2012 to 2021,the wind shear power law formula was used to extrapolate specific wind speed thresholds corresponding to three conditions of non-operation,full capacity operation,and cut-out wind power generation at the observation heights of the weather stations.The statistical analysis was conducted of the an-nual total duration,continuous duration,and yearly variability of these specific wind speeds and their climatic char-acteristics,as well as assessing their impact on wind power generation.The results indicate that the western region of Jilin province possesses favorable wind energy resources,characterized by high annual average wind speeds,a high occurrence frequency of full capacity wind speeds,and a short duration of non-operation wind speeds,impl-ying infrequent wind speed conditions unfavorable for wind power generation.The best wind resources in this re-gion were observed from March to May,with higher monthly average wind speeds.Relatively favorable wind re-sources were concentrated in January,July,August,and December,with comparatively lower monthly average wind speeds and longer duration of non-operation wind speeds.The least specific wind speeds conducive for wind power generation occurred in February,May,and June.In the eastern parts of the western Jilin province,the wind re-sources were relatively unprominent,with lower annual average wind speeds compared to the western parts,longer periods of non-operation wind speeds,a lower frequency of full capacity wind speeds,and virtually no occurrences of cut-out wind speeds.关键词
