Abstract
Distributed generators (DGs) are heavily integrated with the power system network through the power electronic inverters. Such inverter based distributed generation (IBDG) system increases the vulnerability of the system due to faults. In this study, we develop a control and protection strategies of IBDG system employing superconducting fault current limiter (SFCL). The mathematical model of SFCL is developed based on transition period, fault occurring time, and maximum resistance during current limiting state. The detailed modeling for the SFCL, DG, voltage source inverter (VSI), and associated controllers is presented. In order to insert the limiting resistance dynamically during contingencies depending on critical current, SFCL is placed between the VSC and grid. The advantages of the proposed approach are manifolds: simplest control of system faults, and lossless operation during normal conditions. Several disturbances are applied in the system to see the positive impacts of the proposed approach. The comparative analytical results show that the protection approach well restricts the fault current within the tolerable range of the system and its converters.
