摘要
[目的]核聚变作为一种新型核能利用形式,其清洁绿色特性被视为人类未来的“终极能源”,也是我国在能源发展道路上的必经之路。在热核聚变发电厂中,中国聚变工程实验堆(CFETR)聚变反应堆具有一定周期性、脉冲式的输出特性,而汽轮发电机组的运行是稳定、连续的,因此核岛和常规岛之间需配有储能岛以进行储能缓冲;为实现其储能缓冲的功能,储能系统需选择合适的运行模式。[方法]核岛与常规岛耦合运行或解耦运行,对应着储能系统不同的运行模式;文章基于CFETR核岛侧的功率输出特性,从系统配置、设备选型和运行控制等方面对储能系统运行模式的不同方案进行分析和对比。[结果]研究结果表明,核岛与常规岛的解耦运行模式在常规岛发电效率、设备设计技术成熟性和机组运行控制上都更具优势,因此推荐热核聚变发电厂储能系统采用解耦运行模式。[结论]储能系统解耦的运行模式方案大都采用成熟技术,可进行规模化的商业应用,因此可为实现热核聚变发电厂的商业化设计提供支撑。
[Introduction]As a new form of nuclear energy utilization that is green and clean,nuclear fusion is regarded as the"ultimate energy"of mankind in the future and also as an inevitable route for China's energy development.In thermonuclear fusion power plants,China Fusion Engineering Test Reactors(CFETR)have periodic and pulse energy output,while turbine generator units operate stably and continuously.Therefore,an energy storage island is required between a nuclear island and a conventional island for energy storage buffering.To realize such a buffering function,a suitable operation mode needs to be selected for the energy storage system.[Method]The coupling and decoupling operation of the nuclear island and conventional island corresponded to different operation modes of the energy storage island.Based on the power output characteristics of CFETR,different operation mode schemes were analyzed and compared from aspects such as system configuration,equipment design and operation control.[Result]The results show that the decoupling operation mode of a nuclear island and conventional island is superior in terms of power generation efficiency,maturity of equipment design technology and operation control of generator units,so it is recommended to adopt the decoupling operation mode for the energy storage system in a thermonuclear fusion power plant.[Conclusion]Most of the decoupling operation mode schemes for the for the commercial design of thermonuclear fusion power plants.
