Abstract

The world´s first high-temperature superconductor (HTS) power substation (the substation) for the only power distribution grade has been successfully developed in live grid in 2011 in Baiyin, Gansu Province of China. This 10 kV HTS power substation is an integration of 75 m/1.5 kA HTS power cable, 10 kV/1.5 kA HTS fault current limiter, 1 MJ/0.5 MVA high T_c superconducting magnetic energy storage and 630 kVA/10 kV/0.4 kV HTS power transformer. The HTS power substation is operated automatically by a real-time measuring and control system, and it is not necessary to have anyone on duty. Software is developed by using LabView program. The cooling system providing a low-temperature environment for the cryogenic devices is an independent system, and is also the key part to ensure the run of the substation. The real-time measuring and control system for the substation, which comprehensively measures and controls the related signals of the HTS power substation, is introduced, and the controlling system for the cooling system is described in detail in this paper.
