Abstract ABSTRACT Although many attempts have been made to construct an economically feasible Fault Current Limiter (FCL), no FCL has yet been widely accepted by the power industry. This thesis presents a novel fault current limiter for power system applications that is both economically feasible and practical. The work includes two parts. The first part proposes the new topology and analyzes the circuit operation principle in detail. Thus circuit simulations are presented to verify the feasibility of the novel fault current limiter and the control structure for the operation of the FCL is developed. The second part is the construction of a working prototype and the testing to verify the operational principle and the simulation results. The Novel Fault Current Limiter is constructed from off the shelf components making it an economically viable current limiter right now as opposed to costly superconducting FCLs’. A full control system has been developed and a prototype built and tested at the Center for Advanced Power Systems. The experimental results have confirmed the simulation results and it has been concluded that the Novel Fault Current Limiter is an economic and viable alternative to the FCL’s available today.
