Fault Current Limiter (FCL) in Distribution System for Improve the Power Quality

Continues growth of electrical energy demand is resulting in a corresponding increase in the short circuit in power system, which results in voltage sag problems and threat to power quality in the system. Several solutions have been implemented, including the use of Fault Current Limiter (FCL), in order to reduce circuit breakers rated capacity and to limit the electromagnetic stress in associated equipment. This paper presents a study of the impact of fault current limiter in power system performance and hence improving the power quality. In order to evaluate the impact of fault current limiter in power system performance, simulation models of power system performance with ‘FCL’ are used. For simulation model development, MATLAB simulation tool “SIMULINK” software is used. A distribution system fed from single source is used to assess the impact of ‘FCL’ to power system performance.
