风力发电的环境价值与经济性分析

Environmental Value and Economic Analysis of Wind Power

为了对我国风力发电的环境价值和经济性比较有进一步认识,在现有排污收费标准和美国环境价值标准的基础上以预防污染发生的代价作为环境成本,对风力发电的环境价值以及风电和火电经济性展开分析研究.通过对燃煤火电污染物排放率和污染物环境价值标准的计算,得到风电相对火电的环境价值为0.087 3元.kWh-1.计算结果显示,风电成本为0.354 0元.kWh-1,火电成本为0.299 3元.kWh-1;但若考虑环境价值,则火电成本为0.386 6元.kWh-1,高于风电成本.表明风电具有良好的经济性和广阔的发展前景.

The paper presents a study of the environmental value of China＇s wind power and an assessment of its economy. A comparative study is conducted between the wind power and coal power with the prevention price based on China＇s pollution charge schedule （PCS） and US environmental value schedule （EVS） as the environmental cost. The pollutant emission rate of coal power and the pollutant environmental value schedule were calculated. Results show that the environmental value of wind power is 0.087 3 yuan ·kWh^-1 in comparison with coal power, and the cost of wind power and coal power are 0. 354 0 yuan ·kWh^-1 and 0.299 3 yuan ·kWh^-1 respectively. However, if taking environmental value into account, the cost of the coal power is 0. 386 6 yuan ·kWh^-1, which is higher than that of the wind power. It＇s concluded that the wind power is promising in future due to its economy and environmental value.
