Abstract:Utilization of HTS cable lines in electrical grid enables enhancement of the transmission capacity, reduced power losses, lowering of allotment areas, improvement of environmental conditions and improvement of fire and explosion safety. Russian Federal Grid Company of Unified Energy System (FGC UES) started with the development and construction of a HTS DC cable link, which included the cable, cryogenics, AC/DC/AC converters, terminations and cable coupling joints. The link will connect two substations on downtown area. The purpose of this project is to operate at 50 MW HTS cable in the live network of St. Petersburg in order to demonstrate its effectiveness and improve the reliability of the grid. The length of the HTS cable pass will be about 2.5 km. Nowadays, all the elements of the line and all technologies required for cable manufacturing are developed. After successful tests of two 30 meters HTS cable samples together with current leads and coupling boxes, full scale production of all devises for HTS DC cable line was began.
