摘要： 储能电站可解决可再生能源间歇性和不稳定性的问题,满足常规电力系统和区域能源系统效率,安全性和经济性的迫切需要.本文提出了一种新的蓄热电站技术----独立熔盐蓄热电站,进行了独立熔盐蓄热电站原理的介绍,概念设计和技术经济评价.结果表明:独立熔盐蓄热电站初期投资很低,仅为6152.88元/kW,投资回收期短,在3年以内.独立熔盐蓄热电站占地面积小,可建在城市中实现热电联供,总能效率可由单纯发电的30%提高到80%以上.

关键词: 储能, 熔融盐, 蓄热, 电站

Abstract: Energy storage power station is an effective method to meet the urgent demand for solving the problem of intermittency and instability of renewable energy and improving the efficiency, security and economical efficiency of conventional electric power system and the regional energy system. A new kind of thermal storage power station technology----Independent thermal storage power station with molten salt is proposed in this paper. This paper outlines the principle, conceptual design and techno-economic appraisal of the independent thermal storage power station with molten salt. The results show that initial investment of the station is very low, only 6152.88yuan/kW. Its payback period is short, within three years. Independent storage plant with molten salt can set up in cities and towns with less area occupation and the plants can realize the cogeneration of heat and power. Total efficiency can be raised from 30% for power only to more than 80% for cogeneration.

Key words: energy storage, molten salt, thermal storage, power station
