Abstract
Voltage sag problems are the most frequently occurs in three-phase loads. When voltage sags are occurred in distribution system due to the nonlinear loads, transformers which are connected to critical loads are affected by inrush currents. Voltage sag compensator of series voltage source inverter type with transformer coupling is proposed in this paper for voltage sag compensation in power system. Flux linkage problems are occurs at time of voltage recovery from external device. Inrush currents are the severe problems, these causes failure of distribution equipments when entered into the system. At the time rectification of problem interruption in supply is occurs. In this paper an efficient inrush mitigation technique for series voltage sag compensator with feed-back controller is described. The performance of the proposed voltage compensator is verified by using MATLAB/ simulink software. Performance characteristics are described in simulation results of this paper
