Simulation and analysis of HTS resistive and PEFCL for fault current and voltage sag mitigation in power system network

Linear growth of Electrical energy demand in the world resulting in a consistent increase in the short circuit level in power system network, which effects in blackout. Usage of renewable energy to meet demand without proper synchronization will result in power quality problems like voltage sag, swell etc. Power System engineers at utility side are facing challenges of integrating new generation of power and renewable energy into existing power systems network. The High Temperature Superconducting Fault Current Limiter (HTSFCL) and Power Electronic Fault Current Limiter (PEFCL), offers a possible solution to the power system network. Power quality problems caused by short circuit and renewable energy sources which has been simulated and analysed in this paper. The simulated results are analysed for the effect of resistive HTSFCL in both single and three phase power system network performance to reduce fault current level and PEFCL for both single and three phase power system network recital for fault current and power quality and also the total harmonic distortion (THD) is analysed during the fault with MATLAB Simulink.
