“…The analytical approach fall short of calculating the core saturation depth of such devices which is a crucial design parameter [7] [8]. Recently, many PMFCL designs are introduced [4] [6], these designs are mainly address the topology of the magnetic circuit. The numerical approach design of PMFCL was reported in [5], 2D FEM software was used in the designs of PMFCL, the FEM magnetostatic solver was the design tool in the analysis of excitation system of many proposed PMFCL configurations.…”

“…Among the promising techniques to limit the fault current is the magnetically saturated reactor in which the biasing is achieved by a permanent magnet assembly. Hence a permanent magnet fault current limiter (PMFCL) has recently attracted a lot of interests of researchers and scientists [4], [5]. The PMFCL is a nonlinear impedance device connected in series in an electrical power system.…”

As the electrical power grids are extending in capacity with connection of distributed generations, the fault current level is increasing and approaching the capacity limits of the circuit breakers. In this paper, a saturated inductor fault current limiter (FCL) based on permanent magnet biasing has been developed to overcome the inherent disadvantages associated with many previous technologies such as superconducting based techniques. A 3D Finite Element Modeling (FEM) is used to develop and validate the proposed design and compared it with air-cored inductor. A lab-scale prototype was built to verify the design. Furthermore, a scaled up model which could be introduced to 11 kV network is introduced and its electromagnetic performance is evaluated.

The main aim of this work is to design and test a permanent magnet fault current limiter (PMFCL) to limit the fault current in electrical power system network. The (fit and forget) device presented in this thesis is based on two important aspects; the best selection of the state of the art soft and hard magnetic materials and the design topology of PMFCL. Rare I would like to express my sincere thanks and greatest gratitude to my thesis supervisor Dr Faris Alnaem for all his help, advice, comments and guidance in the completion of this thesis. In addition, I would like to give my thanks to my second supervisor, Dr Walid Issa for his help, suggestions and advice. My thanks to the Electrical and Electronic Engineering Department's staff members for their assistance in obtaining the different parts I needed for the experimental work of the PMFCL. My thanks to my friends. My special thanks to my family especially my sons (Mahmud and Yousef) for their support.
