متن کاملAn Optimal Design Approach for Resistive and Inductive Superconducting Fault Current Limiters via MCDM Techniques
The design process of a superconducting current limiter (SFCL) requires simulation and definition of its electrical, magnetic and thermal properties in form of equivalent circuits and mathematical models. However, any change in SFCL parameters: dimension, resistance, and operating temperature can affect the limiting mode, quench time, and restore time. In this paper, following the simulation of...
متن کاملComparison between inductive and resistive SFCL in terms of current limitation and power system transient stability
In this paper, authors present a comparative study of inductive and resistive superconducting fault current limiters (SFCL) from current limitation and power system transient stability point of view. Different types of SFCL can be used to decrease the amplitude of fault current in a power system. The two most used are resistive type (rSFCL) and inductive type (iSFCL). However, no studies have b...
متن کاملEnhancement of Multi-machine Power System Transient Stability Using Superconducting Fault Current Limiters with YBCO and Bi-2212
One of the worst types of fault that a power system should be designed to withstand is a short circuit. Within the various types of fault current limiters, the superconducting fault current limiter (SFCL) has an extremely fast current limitation. The rapid switching action and the self-sensing nature of the superconductor make SFCLs particularly attractive in fault protection. This very fast ti...
متن کاملPower flow analysis and optimal locations of resistive type superconducting fault current limiters
Based on conventional approaches for the integration of resistive-type superconducting fault current limiters (SFCLs) on electric distribution networks, SFCL models largely rely on the insertion of a step or exponential resistance that is determined by a predefined quenching time. In this paper, we expand the scope of the aforementioned models by considering the actual behaviour of an SFCL in t...
