Due to the increase of electric power consumption and the development of distributed generations (DGs), the short-circuit levels are rapidly rising which may exceed the maximum short-circuit capacity of grid equipment. Fault current limiter (FCL) is one of the most effective methods to limit excess current. Various types of FCLs such as superconducting, solid state, saturated-core and hybrid topologies...
As the level of short-circuit fault current gradually approaches the maximum value that the breaker can cut off, effective ways to limit it have to be found. The saturated-core superconducting fault current limiter (SCSFCL) is a kind of current-limiting device based on the nonlinear activity of the steel core.
With electric power consumption and distributed generations (DGs) keep growing, fault current levels are rapidly rising. Many approaches to limiting fault currents have been considered. Changing the grid topology or sequential tripping is costly, complex and may affect the stability of grid. On the other hand, uprating of circuit breakers and other equipment can be very expensive [1]. Fault current...
Underground high temperature Superconductor (HTS) power cables have attracted extensive interest in recent years due to their potential for high power density. With funding support from the United States Department of Energy (DOE), the world's first transmission voltage level HTS power cable has been designed, fabricated and permanently installed in Long Island Power Authority (LIPA) grid. The HTS...
