Analysis of the Self-Protection HTS Cable in Low Voltage DC Microgrid

With the wide access of distributed new energy generation, more and more DC driven loads, many occasions are more suitable for using DC distribution network to transmit power. When HTS cable is used in DC microgrid, it can not only play the advantages of small size, light weight and high-power density, but also reduce the insulation difficulty of cable. When a short-circuit fault occurs in the DC microgrid, the HTS cable can not only effectively limit the short-circuit fault current on the fault branch line, but also protect the voltage and current of the load on the adjacent branch line to a certain extent.
