Integration of unique switch type Fault Current Limiter to mitigate the power quality problems in distribution system

Abstract

In modern power distribution system, increasing the growth of electrical power demand is destined to increase the number of the short circuits in the power system network. So, many imperative methodologies are concerned and are evaluated to establish satisfactory operation. In that Fault Current Limiter (FCL) suggests the best way to minimize the short circuited stresses & may bourn the electromagnetic stress over associated devices. It also reduces the rated capacity of circuit breakers for fault initiated transients from effecting spurious trips. This analysis illustrates the utilization of proposed FCL for analyzing power system dynamics and mitigation of fault conditions at Point of Common Coupling (PCC). The paper highlights the integration of a single switch with current controlled three phase FCL. It offers favorable merits with several faults such as LG, LLG, LLLG faults as shown by using Matlab/Simulink tool.
