With the rapid development of DC power grids, protection grids is particularly important. Therefore, this paper proposes a kind fault current-limiter with instantaneous by-pass current-limiting reactance, analyses its working principle and theoretical calculations, verifies correctness through simulation experiments. At same time, experimental results show that proposed in can not only instanta...

Distribution systems across most parts of the globe are highly radial in nature. As loads are gradually increased on a particular distribution system, a higher operating current state leading to increased fault current levels is attained. Hence, the relay co-ordination is disturbed and equipments such as feeders and circuit breakers need to be replaced with higher rating so that they can handle...

In this paper, an application of superconducting fault current limiter (SFCL) is proposed to limit the fault current that occurs in power system, SFCL is a device that uses superconductors to instantaneously limit or reduce unanticipated electrical surges that may occur on utility distribution and transmission networks. Due to the difficulty in power network reinforcement and the interconnectio...
