“…The drive will absorb a small amount of energy from the rotating load to maintain the DClink at a specified level and maintains the specified DC-link for few seconds during a dip that does not exceed 20%. Here, no additional cost is included only small software modification is required but provides ride-through only for sags of 20% and reduced speed may not be acceptable for certain loads [7][8].…”

Electric power quality encompasses voltage transients, sags, swells, voltage distortions and momentary interruptions (outages) etc There are different techniques to enhance ride-through capability of ASD's during voltage sag conditions. These are aimed at maintaining the DC-link voltage constant by injecting energy from an external source. Ultracapacitors, as storage device, are of reduced size as compared to batteries and provide fast energy exchange. In this paper, the improved performance of ASD's with Ultracapacitors at DC-link during various electric power system faults is demonstrated using MATLAB simulation.and physical experiments were carried out to verify the correctness and validity of proposed ASD ride through topology and control strategies.The performance of ASD under healty and abnormal condition is first simulated in MATLab simulink and then the same are verified using designed hardware setup. The LABView (8.5) software and DAQ board has been used to record the generated waveforms during various power quality disturbances.

“…Battery backup systems operate similarly to adding capacitive energy storage, with the advantage that their energy per volume ratio is much higher than standard capacitors [6][7][8][9]. The batteries are easily available with low cost; provide ride-through for deep sags and full outages.…”

Voltage unbalance or sag conditions generated by the power system faults can have a significant negative impact on the ASD's (Adjustable Speed Drives). A practical ride-through scheme based on supercapacitor/ battery as an energy storage device for ASD's is presented in this paper. Energy storage module is connected to support the DC -link voltage during power system faults. The performance of ASD's under normal and power system faults is first simulated in MATLab Simulink and then experimentally verified. The Data AcQuisition boards (DAQ) of National Instruments along with LabVIEW software have been used to record the observed waveforms.

Adjustable speed drives are highly sensitive to voltage sags.. In this paper an appropriate ride-through scheme based on Supercapacitor as an energy storage device for ASD (Adjustable Speed Drive) during various power quality events has been presented. The proposed compensator topology has been evaluated analytically using MATLAB and experimentally verified. The LABView (8.5) software and DAQ board has been used to record the generated waveforms during normal and abnormal conditions.
