Study on Chemotherapy Agents in Saliva through Spectrometry and Chromatography Methods Correlated with Periodontal Status in Oncology Patients | Chapter 8 | Innovations in Science and Technology Vol. 1

 This paper describes the usage of a battery-based dynamic voltage restorer (DVR) to alleviate voltage sag and swell. During sag/swell, the DVR is a three-phase controlled voltage source with a magnitude and angle that adds/subtracts from the source voltage. In each phase, the DVR can inject a voltage of the required magnitude and phase at the fundamental frequency. The DVR can restore the load voltage in milliseconds. DVR can fix voltage sag and voltage swell problems fast and effectively. To estimate reference voltages, the Synchronous Reference Frame Theory (SRFT) is employed, and gate pulses are generated by monitoring the source, load terminal voltages, and supply currents. The reduction of voltage sag and swell using SRFT for battery-based DVR is simulated using MATLAB/ SIMULINK and the power system Block set (PSB) toolboxes.
