摘要：The high-temperature superconducting (HTS) energy storage device with the world's largest capacity recently broke ground in Cuihen

The high-temperature superconducting (HTS) energy storage device with the world's largest capacity recently broke ground in Cuiheng New Area, Zhongshan. As a demonstration project supporting China's national major R&D program "High-Performance HTS Materials and Applications of Magnetic Energy Storage" in Zhongshan, the device can provide ultra-stable power to high-tech enterprises. It is scheduled to be completed and put into operation by November this year.

HTS energy storage technology is considered a crucial enabler in building China's new power system and achieving carbon peaking and carbon neutrality goals. The demonstration project is next to the 110kV Binhai Substation on Ma'an Island in the Cuiheng New Area. The device comprises multiple major parts including superconducting magnets, cryogenic cooling systems, converters and monitoring systems, with a maximum output power of no less than 5 megawatts and a storage capacity of no less than 10 megajoules.

Currently, chemical storage systems dominate the power grid, and they can restore electricity within seconds after an outage. However, with the growing cutting-edge enterprises, they put forward higher requirements on power quality and supply stability and the need for the application of high-performance HTS materials and magnetic energy storage technology. Since the launch of the Shenzhen-Zhongshan Link, a large number of high-tech enterprises have been established and put into operation, which not only call for a higher electricity demand but also stricter requirements for supply reliability.

This is where the HTS magnetic energy storage device comes into play. "HTS magnetic energy storage features both lossless and ultra-responsive. It reacts within milliseconds, over ten times faster than traditional chemical storage systems. With this technology, even during a power outage, neither residents nor the device itself would notice any disruption, so it can effectively meet the needs of high-precision industries for stable power supply." said the manager of the project. The HTS technology deployed in this project offers not only lower operational costs compared to low-temperature superconducting systems but also broader application potential and higher commercial value.

全球容量最大高温超导储能装置在中山开工

全球容量最大的高温超导储能装置日前在中山市翠亨新区落户动工，这是国家重点研发计划“高性能高温超导材料及磁储能应用”在中山配套落地的示范工程项目，能为高新企业提供超级稳定的电能。项目预计今年11月建成投入使用。

据悉，高温超导储能技术是推动我国新型电力系统建设，助力实现“碳达峰、碳中和”目标的关键技术之一。此次落地的示范工程项目坐落于翠亨新区马鞍岛110kV滨海变电站旁，该装置由超导磁体、低温制冷系统、变流器及监控系统等关键部件组成，最大输出功率不低于5兆瓦，储能量不低于10兆焦。

目前，电网普遍采用的化学储能方式，虽然已经做到线路断电后能以秒为单位恢复供电的先进水平，但随着高精尖企业的增多，企业对供电稳定性的质量又提出了更高的要求，需要应用高性能的高温超导材料及磁储能技术。据悉，深中通道通车以来大批高科技企业陆续建成投产，这批企业对电力的需求不光量大，而且对稳定性的要求很高。

“高温超导储能装置”应运而生。“高温超导磁储能的特点一是无损，二是响应快，能达到毫秒级，比传统的化学储能快10倍以上。有了该技术设备的保障，断电情况下不但居民感受不到，甚至设备本身也感受不到，能有效满足高精密企业对稳定电力供应的需求，为生产生活保驾护航。”项目负责人表示，该项目拟落地的高温超导技术，不但使用成本比低温超导低，而且使用领域更广，商业价值更高。
