The world's first High-Tc superconducting power substation, which was developed by the Institute of Electrical Engineering, Chinese Academy of Sciences (IEE CAS), was put into operation officially in the power grid in Baiyin city, Gansu province, China. The substation with voltage level of 10.5 kV, which is located at the National High-Tech Industry Park in Baiyin city, integrates a 1 MJ/0.5 MVA high temperature superconducting (HTS) magnetic energy storage devices (SMES), a 3-phase 1.5 kA high-Tc superconducting fault current limiters (SFCL), a 630 kVA high temperature superconducting (HTS) transformer, and a 75m long/1.5 kA 3-phase AC HTS transmission cable. These new-type superconducting power devices can enhance the stability and reliability of the grid, improve the power quality, decrease the system losses and reduce the occupation area of substation. Till now, it is the only distribution-level High-Tc superconducting substation in the world, which creates the world’s first and China’s first in many areas. Nearly 70 completely independent intellectual property rights were obtained. It integrates the latest and the most advanced research results of superconducting power technology of recent 10 years in our country. Its operation marked a significant breakthrough of our country's superconducting power technology.
