基于全生命周期评价方法的风电环境效益测算——以内蒙古某风电场为例

Analysis on Environmental Benefit of Wind Turbines Using Life Cycle Assessment——Case Study of Some Wind Farm in Inner Mongolia

选取内蒙古某风电场作为"三北"地区风电场的典型案例,采用全生命周期评价方法,从原材料生产、运输、施工建设和报废等4个阶段分析其能耗及对环境的影响。经过对比测算,该49.5MW风场与传统300MW的蒸汽轮机发电机组相比,每MWh能耗约为传统火电厂的3.5%,全球变暖潜力只有煤电发电的1.5%,酸化潜力只有煤电的0.8%,该结果论证了在"三北"地区建设风电场的环境效益十分显著。

This paper selects a wind farm in Inner Mongolia as a typical case of the ＂ Three North＂, and applies life cycle assessment to analyze its energy consumption and environmental impact from four stages, which are manufacturing, transportation, construction and diposal stage. The research indicates that the per MWh energy consumption, the global warming potential and the acidification potential of the wind farm is 3. 5% , 1.5% and 0. 8% of the conventional thermal power plants respectively, compared with 300MW Turbine Generator Set. The results demonstrates that wind energy development in the ＂ Three North＂ will bring significantly environmental benefits.
