Description

An magnet was manufactured and tested for a 1 MJ/0.5 MVA Superconducting Magnetic Energy Storage and Fault Current Limiter system (SMES-FCL) with HTS tapes recently. It consists of 46 double pancakes with an inductance of 13.3 H, and the rated operating current is 388 A, the maximum magnetic field is up to 3.5 T. In this paper, the fabrication and tests of the 46 double pancakes, the assemblage of the magnet are described in detail. And then, the fundamental performances testing of the magnet were carried out at liquid nitrogen and sub-cooled liquid nitrogen, respectively. And then, the magnet was soaked in liquid neon and cooled with four AL325 cryo-coolers to keep zero neon vaporization. After the whole 1 MJ/0.5 MVA SMES-FCL were field installed and tested, it had been put into operation since January 6 of 2017 at a 10.5 kV wind farm locating in Yumen, Gansu Province of China.
