Abstract
Abstract
Fault current limiters (FCLs) play a critical role in today’s power systems. It is considered a commercial solution for high short circuit current limitations, power system safety, and reliability improvement. The thesis reviews state-of-the art FCLs in the power system and their operation theory. Two novel compact structure, self-triggered, fast recovery and improved performance three-phase inductive FCLs, are proposed. The two models have been analysed and numerically simulated under a finite element model (FEM) environment. The principal operation, parameter selection, and performance validation under different fault conditions have been illustrated. Each model structure uses only one magnetic core to minimise the size, weight and construction costs. The analyses include 3D modelling, electromagnetic fields modelling in a simple power system simulation. Experimental analysis is included to validate one of the models in a laboratory electric power system model. The simulation and experimental results approve the effectiveness of the proposed structure for high short circuit currents limitation, negligible effect during the normal operation, in addition to very fast recovery time after fault clearance. The validated inductive FCL model has been used with IEEE-9 Bus RESs Integrated Power System, and different scenarios have been concluded.
