Mitigation of Voltage Sag and Swell by Using Magnitude Tracking Method

Our project proposes a concept to mitigate the voltage sag and swell. There are three types of voltages is being considered. Normal voltage, Lower voltage (sag), Higher voltage (swell). Normal voltage is being considered so as to keep it constant throughout. Our project deals that if sag or swell happens, the automatic correction with comparison of magnitude voltage using DVR and this mitigation of voltages controlled by a PIC controller. The voltage inverter operation is much reduced and thus the efficiency and reliability of the system is improved in an effective manner.
