摘要
为研究风电场运行全过程的碳排放和能源消耗,建立了系统动力学模型进行预测模拟和不确定性分析。结果表明,风机生产与运输阶段的CO2排放和能耗占比最大,废弃处置阶段的资源回收对于CO2排放和能源消耗具有抑制作用,材料的大量消耗是造成CO2排放量和能耗量巨大的主要原因;提高生产工艺和风电场建造技术,降低材料的CO2排放系数、能耗系数和材料的消耗量,以及提高金属材料的回收率能够显著降低CO2排放总量和能耗总量。与发电量相同、运行周期同为20 a的火电厂相比,风电场能够减少CO2排放660.5万t。
In order to study the carbon emissions and energy consumption of the entire process of wind farm operation,a system dynamics model was established for predictive simulation and uncertainty analysis.The calculation results showed that the CO2 emissions and energy consumption in the wind turbine production and transportation stage accounted for the largest,and the resource recovery during the waste disposal stage had an inhibitory effect on CO2 emissions and energy consumption.The large consumption of materials was the main reason for the huge amount of CO2 emissions and energy consumption.Uncertainty analysis and sensitivity analysis show that improving the production process and wind farm construction technology,reducing the CO2 emission coefficient and energy consumption coefficient of the materials as well as the consumption of materials,and increasing the recovery rate of the metal material can significantly reduce CO2 emissions and energy consumption.Compared with the thermal power plants with the same generating capacity and 20 years’operation cycle,the wind farm can reduce CO2 emissions by 6.605 million tons.
