摘要
应用生命周期分析法(LCA),对风力发电的电厂用材冶炼、材料运输、电厂建设这3个阶段进行分析,分别计算3个阶段中的单位能耗和环境影响,并与燃煤发电进行比较。结果表明,每发10MW·h电量,风力发电可节省3.731t标准煤,减少排放粉尘0.49887t,CO_29.935t,NO_x0.0499872t,SO_20.07885t,说明风力发电具有显著的节能和环保效应。
Three stages such as steel-smelting, material transportation and power station building are analyzed by means of Life Cycle Assessment, and the energy consumption and environmental impact are calculated in each stage, and the comparison with coal-fired thermal power generation is done as well in this paper. The results show that for every output of ten thousands of k W · h electric power, the standard coal consumption could be saved by 3.731 tons, the emission of CO2, SO2 and NOx could be decreased by 9.935 tons, 0.078 85 tons and 0.049 987 2 tons. On the basis of above results, wind-power generation has been proved that it has remarkable effect on energy saving and environmental protection.
