摘要
[目的]近年来,聚变装置装机容量在不断增加,其电源系统需要输出高幅值、长脉冲的功率,对电网造成了极强的功率冲击,严重时会导致电源脱网,严重威胁聚变装置的安全.同时,高幅值脉冲也使电源系统的设计存在大量冗余.[方法]为了解决这两个问题,提出了带储能装置的新型聚变电源拓扑,通过在电源系统中加装储能装置,缓冲脉冲功率对电网的冲击.在电源运行过程中,电网提供稳态功率,储能装置提供脉冲功率,有效降低电源的成本.[结果]根据工业供配电经验,得出了不同拓扑中主要元件的选型计算公式.最终根据仿真数据,对不同电源拓扑的成本展开分析对比.[结论]证明了新型电源不仅可以减小对电网的功率冲击,提高电源系统的能量利用率,也可以降低变压器容量,具有一定的成本优势.
Abstract
[Introduction]In recent years,as the installed capacity of the fusion device has been increasing,the power supply system of the device requires high-amplitude and long-pulse power output,which causes a strong power impact on the grid,and even power supply disconnection in severe cases to pose a serious threat to the safety of the fusion device.Additionally,the high-amplitude pulses also result in a lot of redundancy in the power supply system design.[Method]To solve these problems,this paper proposed a novel fusion power supply topology with energy storage,that is,the power supply system was designed with energy storage to mitigate the impact of pulse power on the grid.During the operation of the power supply,the grid provided steady-state power while the energy storage device delivered pulse power,effectively reducing the cost of the power supply.[Result]According to the experience in industrial power supply and distribution,this paper presents the calculation formulas for the selection of key components in different topologies and conducts a cost analysis and comparison for different power supply topologies based on simulation data.[Conclusion]The experimental results show that the new power supply topology not only reduces the power impact on the grid and improves the energy utilization of the power supply system,but also reduces transformer capacity,thus it is cost-efficient.
