Abstract.
The paper briefly presents the results of the superconducting DC line development for the power system of St. Petersburg. The main attention is paid to the investigation of threatened emergency operation associated with break- downs in the cryogenic system. Analysis of the data obtained during emergency operation tests of the helium management system for a cable line is presented. Circuit diagrams of the helium management system are provided. Maximum admissible limits of the helium management system for high-temperature super- conductor cable (HTS) during emergency operation are determined. Potential transmission time of the rated power by cable in case of various cryogenic system failures was evaluated. As a result, an adjustment to the created interlock and protection system of HTS cable helium management system was proposed for enhancing the operation reliability in various modes.
