摘要： 应用生命周期分析法(LCA),对风力发电机从原材料的生产制造、运输、建设、运行及拆除报废各阶段进行分析,分别计算各阶段的环境负荷,最终用全球变暖潜力和酸化潜力指标表示,并与燃煤发电进行比较.以沈阳市法库县望海寺风力发电场为实例进行分析,结果表明,在风力发电机的一个生命周期内(平均为20年),环境负荷较大的过程为原材料的制造、发电场的建设与运行维护两个阶段,并且每发电10 MW.h,相对于燃煤发电相比,风力发电可省3.96 t的标准煤,可减少向大气排放CO29.77 t,NOx0.050 t,SO20.02 t,全球变暖潜力(GWP)和酸化潜力(AP)分别是燃煤发电的1.08%和3.12%,但建...

Abstract: The life cycle assessment (LCA) was applied to analyze each stage of a wind turbine including manufacturing of raw materials and transportation, building, use and dismantling of the equipment, and environmental load of various stages was calculated respectively. The environmental load was described by indexes of global warm potentiality (GWP) and acidification potentiality(AP), and the wind turbine and a coal generator were compared and analyzed. Taken Wanghai Temple wind farm in Shenyang as a case study, the results showed that, during a life cycle of the wind turbine (average 20 years), the larger environmental load processes are the manufacture of raw materials and construction, operation and maintenance of power stations, and in contrast to a coal generator, the wind turbine can reduce 3.96 t standard coal, 9.77 t CO2, 0.050 t NOx and 0.02 t SO2 for a 10 MW·h, and its GWP and AP will be 1.08% and 3.12% of a coal generator, respectively. However, it destroyed a large number of ecological resources in construction process. Hence, the environmental protection measures will be further strengthened, and it is important to minimize the damage to ecological resources.
