摘要
应用生命周期分析法(LCA),对水力发电的工程用材的冶炼、材料运输、电能输送这三个阶段进行分析,分别计算三个阶段中的能耗和对环境的影响,并与燃煤火力发电进行比较。结果表明,每发10MW·h电量,水力发电可以节约3.84t标准煤,减少向大气排放CO29.9094t,NOx0.0449t,SO20.07914t,粉尘0.49654t,说明水力发电具有显著的节能和环保效应。
Three stages such as material smelting, material transportation and electricity transmission were analyzed by means of Life Cycle Assessment and the energy consumption and environmental impact were calculated in each stage and the comparison with coal-fired thermal power generation were done as well. The results showed that for every output of ten thousand kW·h electric power output, the standard coal consumption could be saved by 3.84 tons and the emission of CO2, SO2 and NOx could be decreased by 9.9094 tons, 0.079 14 tons and 0.044 9 tons. On the basis of above results, hydropower had be proved that it had remarkable effects on energy saving and environmental protection.
