Applications of Fault Current Limiters

Abstract

This chapter introduces the main components of a power system and discusses their associated vulnerabilities to short-circuit currents. The crucial components for future power systems, among others, include renewable generators, transformers, busbars, HVDC lines, microgrids, electric vehicles, charging stations, battery energy storage systems, and solid-state breakers. FCLs are then presented as protective devices that enhance the resilience of these components against fault currents. The chapter is primarily based on recent research that provides a comprehensive understanding of the impact of FCLs on each specific part of the power system. Finally, the effects of FCLs on different sections of the power system are summarized, and the major findings are briefly discussed.
