Study on Operating Characteristics of Distribution Network with Fault-current Limiting-type HTS Cable

The fault-current limiting-type HTS cable (FCL-HTS cable) has the advantages of large surge absorption capability and small volume of the superconducting cable. This paper mainly analyze the characteristic of the urban distribution network with the FCL-HTS cable. Combined with economic analysis, the feasibility of using a FCL-HTS cable to connect with the distribution network is discussed. Based on the model of FCL-HTS cable, the characteristic of fault current and the power flow of the distribution network are analyzed. And the transient stability of the evaluated, which shows the feasibility of adopting fault-current limiting-type HTS cable in distribution network.
