As a rule of thumb, the maximum prospective fault current for a three-phase supply, as shown in Fig 2, can be taken as twice the single-phase value. For example, if the maximum single-phase fault current measurement is 4.6 kA, then the maximum value of fault current between line conductors is calculated as: 4.6 kA x 2 = 9.2 kA.

During a fault, excessive current—called fault current— flows through the electrical system often resulting in a failure of one section of that system by causing a tripped circuit breaker or a blown fuse. A fault current limiter (FCL) limits the amount of current flow-ing through the system and allows for the continual, uninterruptedthe small resistance in the fault circuit. Thus, the fault current-limiting inductance LFCL cannot change the damping characteristics which refer to criterion R <2 p L/C. That is, LFCL can only limit DC fault current, but not relieve the overcurrent e ect in the converter and AC sides [24].

First, the fault mechanism and fault current calculation associated with the DC converter are analysed in this study; subsequently, a multiport superconducting fault-current-limiting circuit breaker (SFCLCB) suitable for a flexible DC power grid is designed. The circuit breaker adopts ground drainage to transfer the fault current. A fault current limiter is a nonlinear element which has a low impedance at normal current levels, but presents a higher impedance at fault current levels. Further, this change is extremely rapid, before a circuit breaker can trip a few milliseconds later. (High-power circuit breakers are synchronized to the alternating current zero crossing to ...
