Fault Current Limiter Based on Triggered Vacuum Switch

摘要

A new type of fault current limiter (FCL) based on triggered vacuum switch (TVS) is proposed in this paper. The TVS- based FCL (TFCL) is mainly composed of a capacitor, a current--limiting reactor connected with a capacitor in series and a TVS con- nected with a capacitor in parallel. With the TVS at off or on state, the whole TFCL behaves as a conventional series compensator or a fault current limiter, respectively. Numerical simulation and prototype experiment based on LC resonant test circuit show that it is feasible to develop TFCL.
