抽水蓄能电站经济环保效益分析

抽水蓄能电站作为一种特殊的发电方式在世界范围内已经得到了广泛应用。但因为抽水蓄能电站引起的系统煤耗减小不易定量说明,现有的计算方法又不易理解,所以在我国存在抽水蓄能电站是能源浪费的错误认识。针对这种情况,借鉴工程热力学中的“等效焓降”的思想,采用项目经济评价中“有无对比”分析方法,建立了抽水蓄能电站经济效益和环保效益的计算模型,形成了抽水蓄能电站节煤、节油、减少投资及运行维护费用、污染物减排的系统计算方法,并以泰安抽水蓄能电站为例进行了案例计算。表明抽水蓄能电站在以上各方面具有显著的效益,对我国的节能降耗和环保具有重大意义。

Analysis on economic and environmental benefit of pumped-storage station

As special power generation mode,the pumped-storage stations have been applied widely in the world.Since the energy saving benefit of pumped-storage stations is difficult to illustrate quantitatively,and the existing calculation method can not be understood easily,the false opinion exists in the power industry that pumped-storage stations in China are sources of energy waste.In view of this,referring to the thought of "equivalent heat-drop",the calculation model of economic and environmental benefit was established based on the method of contract between applying it or not.The systematic calculation method was realized for coal,oil,investment and operation cost saving,and pollutant reduction.The case study in Tai'an Pumped-Storage Station shows that the pumped-storage station is of distinct benefits and great significance for energy saving and environment protection in China.
