New resonance type Fault Current Limiter

This paper proposes a new parallel LC resonance type Fault Current Limiter (FCL). This structure has low cast because of using dry capacitor and non-superconducting inductor and fast operation. The proposed FCL is able to limit fault current in constant value near to pre-fault condition value against series resonance type FCL. In this way, the voltage of point of common coupling (PCC) will not change during fault. Analytical analysis is presented in detail and simulation results are involved to validate the effectiveness of this structure.
