Abstract
The power industry world-wide has seen aggressive power demand growth in the pursuit of economic development of the countries. The power sector, in general, has also gone through reforms in the last decades and the decentralized power generation, transmission, and distribution made the control diversified. Green energy generation technologies are penetrating the power grids, and the parallel addition of bulk power generation plants is also in order. These modern power system requirements lead to complex systems where unforeseen incidents - faults challenged the power utilities to control extensive short circuit currents. The short-circuit levels reached or even exceeds the manageable limits of applied protective gear especially, costly circuit breakers. However, the time-bounded upgrades or replacements are also not financially viable. Saturated Core Fault Current Limiter(SCFCL) technology, a commercially viable option, is considered as a prospective solution to the problem. This paper report the concept validation work in the laboratory and the current limiting performance of the test model. The SCFCL technology development work worldwide with the on-site grid applications of some pilot projects has also been presented. The researcher may find the contents supportive as technical guidance.
Keywords- clipping factor, distributed generation, fault current limiter, short circuit.
