“…It also provides a better support in reactive power at low AC voltage condition than an SVC does. It is because the resulted reactive power decreases linearly when the AC voltage decreases, by maintaining the current at the rated value even at a low AC voltage [26][27][28][29][30][31]. As it involves only reactive power, there is no phase difference between the voltage of the D-STATCON output and the AC system, when circuit losses are neglected.…”

<span>Development of a FACTS device model for mitigating voltage sag is presented. It deals with a static synchronous condenser (STATCON) to be used in the AC distribution networks. Simulation with the help of a commercial software Matlab/Simulink was explored to investigate its characteristics and performance during the voltage sag occurrence. The considered main cause of voltage sag was the starting of high capacity asynchronous motor. A voltage source inverter based on the phase-controlled thyristor components was implemented in this application to compensate the change in reactive power of the system. The concerns have been put on the influence of initial operation point and DC capacitance. The study results show the capability of D-STATCON model to reduce the consequence of voltage sag following the starting of high-power asynchronous motor in the distribution network. A fast response of the condenser work confirmed the desired performance.</span>
