A method for soft-reclosing of fault current limiters (FCLs) is described, which serves to reduce peak currents and stresses on machines when reclosing synchronous generators into an energized power bus and avoid mis-tripping of circuit breakers. This method depends only on local current measurements and is realized by timed closing of parallel switches that are part of the fault current limiter....
With the capacity expansion of power systems, fault currents may exceed the interrupting capacity ratings of circuit breakers (CBs). Inductive fault current limiters (FCLs) are able to effectively limit fault currents and maintain circuit breakers on duty. For power systems of different ratings, it is important to decide whether the parameters of an inductive FCL satisfy the requirement of limiting...
With the increasing capacity of power system, fault currents (CBs) may exceed the interrupting capacity ratings of circuit breakers. Fault current limiters (FCLs) can be applied to maintain circuit breakers within their interrupt ratings. The degree of fault current limiting on system performance is analyzed in radial and meshed system structures. Heavy limitation modes and light limitation modes...
