PSCAD/EMTDC를 이용한 하이브리드 초전도 전류제한기 모델링

The increase of fault current due to large demand has caused the capacity of power machines in power grid to increase. To protect the power system effectively from the large fault current, several superconducting fault current limiters have been proposed. however, in order to apply superconducting fault current limiters into power system, there are many problems such as cost, recovery, AC loss, and cryogenic. In order to solve these problems, hybrid superconducting fault current limiter(HSFCL) was proposed. In this paper, we modeled hybrid superconducting fault current limiter using PSCAD/EMTDC and analyed fault current limiting characteristic and total resistance of hybrid superconducting fault current limiter.
