Optimum location and allocation of fault current limiter in distribution power system using Y-Bus matrix

Abstract

The fault monitoring system is a serious part as one of the components that give the negative impact to the system. The fault needs to identify the magnitude of the nominal current, this magnitude is more than five (5) times greater than nominal current. If this happened on the system, it will cause the disaster on the Power System itself, either, system failure or, system damage. The FCL can be applied to the system for maintaining the circuit breaker operates within their limits/ratings. The Y-Bus Matrix has been implemented to analyse the optimal location of FCL for limit the fault current. This Y-Bus Matrix is identify for each buses declared as a Point of Common Coupling. Different location of fault impedance will be resulting the different location of FCL. Two categories of simulation has been used, Matlab Simulation and Y-Bus Matrix Simulation Technique as an additional support instrumentation. This project discover that FCL should be located in series at high admittance value. The analyses are verified by simulation result.
