| 摘 要： | 以全寿命周期风资源评估思想对未来运营期风资源进行预测分析,得出每年的预测风速,根据此预测风速,得到每年的预测发电量,再进行项目的经济效益评价,从而更加接近实际情况。然后对项目风资源进行敏感性分析,以测风年份风速为基数,以20%的幅度进行敏感性分析,最终得出各个年份的经济效益。根据全寿命风资源理论进行分析得出的结论需要提高风电上网电价,才能使项目盈利。

| Abstract: | The full-life-cycle assessment of wind resources is used to forecast and analyze the future operating wind resources,and the forecast wind speed is obtained. The annual generating capacity is concluded based on the above data,and more accurate project's economic benefit assessment can be obtained. The sensitivity of the wind resources is analyzed. The measured annual wind speed is used as the base data. Based on the 20% range of the sensitivity analysis,the economic benefit of each year is concluded. Accord... |
