故障電流常造成電力系統若干影響，過大的電流會造成系統或設備複雜的損傷，導致於無法修復的情況，嚴重時可能會造成電網上的電壓驟降，發生規模性停擺等影響。本論文提出一新型故障電流抑制器，電流抑制器串接於電源與系統之間。當故障發生時，電流抑制器即時的動作，使得故障電流被有效的抑制。當抑制器回復至穩態後，抑制器仍是持續抑制故障電流，避免過大故障的電流造成系統更大的損傷。並可利用外部的電流偵測警示，排除異常的故障情況。
本論文經由先模擬和實作低壓10.4V，證明抑制器是有效的，再透過模擬觀察新型故障電流抑制器於11.4kV的抑制效果。若藉由適當的設計故障電流抑制器，可以提高保護功能和減少系統的損傷，達到更好的供電品質。

In power system, fault current sometime results in equipment damage, which requires part-replacement. Moreover, severe fault current situation may induce major power outage by causing grid voltage suddenly drop. In this thesis, a novel Fault Current Limiter (FCL), connected between grid and load, is introduced. At the instant of fault, the new FCL limits the prospective fault current immediately while a fault occurs. It keeps bounding the fault current in steady state in preventing over-current damage. An extra current detecting mechanism is added to detect and to end fault situation.

Implementation and simulation of the down scaling system (10.4V) represents the effectiveness of the new FCL. The simulation results of the system model (11.4kV) illustrate its well limiting ability. With a proper design, the new FCL prevents the system damage with better grid quality.
