“…The magnitude of the injection voltage in the in-phase correction for the specified voltage sag state is minimum as compared to the other current compensation methods. The dc-link voltage level is also lower if the form of compensation is in phase[13]. InFig 2, the DVR configuration is shown.…”

Power quality became very important for utilities as well as users. The cause of the power quality problem is instability (voltage, current, and frequency). Voltage sag and voltage swell are common voltage disruptions. They are caused by faults, disturbances arising in the transmission system, etc. This paper deals with the voltage instability compensation of linear sensitive loads by dynamic voltage restorer (DVR) using instantaneous power theory. The practical experiment results were obtained using the data acquisition card (DAQ) and LabView real-time software. The new design can compensate the voltage for ±15% of the nominal value for the two conditions sag/swell. Also, the designed controller enhanced the response of less than 110% overshot at stalling time of less than 0.2 sec.

“…These torsional energies if not contained can travel upstream to the diesel generator and can induce first natural frequency vibration in the diesel generator driveline. As on-board DC system in ships can be equipped with power buffers based on supercapacitors and energy storage devices, this torsional energy transfer problem can be solved [136,137]. To reduce the effects of system load fluctuations, a power buffer (supercapacitor and a hybrid converter combination) is used as fast acting energy storage in marine vessels [11,16].…”
