摘要
当高温超导体处于超导态,永磁体的部分磁力线进入到超导体内,由于磁通钉扎的作用,永磁体无需控制而稳定悬浮,这种悬浮特性称为无源自稳定性。高温超导飞轮储能系统安装了无源自稳定悬浮的超导轴承,具有稳定度高、大容量、高效率以及无污染等优势,在风电和太阳能发电、电力系统调峰和电动汽车等方面具有广阔的应用前景。本文概述了高温超导飞轮储能系统的基本工作原理和主要结构,详细论述了高温超导飞轮储能系统的国内外发展现状,探讨了高温超导飞轮储能系统的关键技术、当前的研究热点和特殊应用。
When the high-temperature superconductor is in the superconducting state, part of the magnetic flux lines enter into the superconductor and the permanent magnet can be levitated stably without control due to flux pinning effect. This levitation is passive self-stable. High-temperature superconducting（HTS） flywheel energy storage system with the HTS bearing（HTSB） has the advantages of high-stability, high-capacity, high-efficiency as well as non-pollution. So it has wide applications in wind power system and solar power system, peak load regulation of power system, electric vehicles and so on. This paper introduces the basic working principle and main structure of HTS flywheel energy storage system. And its development status is presented in detail. In the end, the key technologies, the focus on current research and its special applications are also discussed.
