摘要 风能是可再生清洁能源,但对于风力发电,在发电设备制造和风力发电场的建设过程中,会对环境产生污染和破坏。为评价风力机生命周期内的环境效益,提出了能源利用技术中的一个新概念———清洁度。介绍了清洁度系数的定义和计算方法,分析了该参数的物理意义,并得出结论:提高风力机清洁度的主要手段包括合理选择风场、提高发电效率、延长风力机使用寿命和有效运行时间,以及减少其它能量消耗等。 Wind energy is a renewable and clean energy source; however, the manufacture of wind power generating units and the construction of wind power plants will pollute and damage the environment. To assess the environmental benefits of a wind turbine generator (WTG) during its life cycle, cleanliness, a new concept in the energy utilization technology, is presented. This paper introduces the definition and the calculation method of cleanliness coefficient and analyzes its physics. It is concluded that rationally siting wind farms, improving power generating efficiency, lengthening WTG service life and effective run time as well as reducing other energy consumption are the main methods to enhance WTG cleanliness.
