摘要
能量偿还时间是评价新能源发电能力的重要指标之一。首先,文章针对目前应用广泛的小型风力发电机,给出了一种基于LCA的小型风力发电机能量偿还时间的计算方法,实例分析一台300 W垂直轴风力机,运用Gabi软件计算出其生命周期阶段总的消耗能量;其次,通过试验得出了此型号风力机在不同风速下的功率特性,并仿真计算出此型号风力机安装在桂林尧山景区的年发电量;最后,计算出桂林尧山景区安装该型号风力机时,能量偿还时间为2.36 a。
Energy repayment time is one of the important indicators of evaluation of new energy power generation capacity. In this paper, a method to calculate the small wind turbine energy to repay time has been proposed based on LCA. A 300 W vertical axis wind turbines was analyzed as a case and its expend energy of life cycle phase was calculated by using Gabi software. Then, the output power characteristics of wind turbine under different wind speed were obtained by experiments and the power could generate by this wind turbine model installed on the peak of Yao Mountain in Guilin were obtained by simulation analysis. Finally, the simulation results show that wind turbine mounted on the top of Yao Mountain in Guilin has the energy pay back time of 2.36 years.
