Abstract
In this article, Interline power flow controller (IPFC) has been recommended to limit the short circuit current (SCC) in low voltage (LV) electrical distribution system. Industrial loads are increasing due to various reasons in the distribution system. It leads to the power requirement at the distribution system level. Therefore, there is a scope for increase in the fault current. Due to the increased fault current, the protection of switchgear is vital. A simple control strategy wth IPFC is proposed in the distribution system to limit the fault current. Low voltage distribution system i.e 800 MW thermal power plant water system LV distribution system is considered for demonstrating the effectiveness of the IPFC. Short circuit analysis is performed without and with the IPFC by applying ETAP and MATLAB (SIMULINK). The simulation results are compared. Further, the effect of different ratings of standard transformers is also analyzed. It is noticed that the control strategy with IPFC can limit the fault current.
