【摘要】 抽水蓄能是电网调峰的有效手段之一,近些年正朝着大容量、高水头及快速响应的方向发展。然而,随着我国分布式能源的大规模开发利用、智能电网的发展以及大型抽水蓄能对地理条件极高要求的制约,其正经历着应用模式的变革和向新技术转化的过程。微小型抽水蓄能具有选址相对容易、建设周期短和接入电力系统便利等特点,受到人们越来越多的关注。本文介绍了微小型抽水蓄能技术的工作原理、研究与发展现状,阐述了微小型可逆式水泵水轮机的研制情况,同时对我国微小型抽水蓄能技术的应用领域和发展前景进行了分析。更多还原

【Abstract】 Pumped storage is one of the effective means of power grid peak shaving, which is moving towards the direction of the large capacity, high water head and quick response. However, with the large-scale utilization of the distributed energy resource and the development of the smart grids as well as the restriction of geographic conditions for large-sized pumped storage, the pumped storage is experiencing the reforms of application models and R&D for new technologies. Micro and small pumped storage has the characteristics of relatively easy on location, short construction period and convenient to access to the power system, which is being paid more and more attention. This paper introduces the working principle, research and development status of the micro and small pumped storage technology, expounds the development situation of the reversible pump-turbine, and analyzes the application fields and the development prospects of the micro and small pumped storage in China.更多还原
