Effects of Transformer Connection on Voltage Sag Characterization

Parijat Deb | Amit Gupta ^[8]

Abstract: Day by day with the increase in demand of power supply, people are also becoming aware of power quality. Present generation wants advanced power plant design with the increment of power supply and also the power supply must be of good quality. So, to design power plant, power engineers need to concentrate on how the quality of supply can be improved along with fulfilling all the demands at the same time. In today's era, people are using so many electronic or sensitive devices as per comfort and the same will be happen in future also. These devices are one of the major causes of power quality disturbance. To maintain the quality of the power, engineers need to design their system in a way such that these devices can not seriously affect the quality of the power. In this paper disturbance of power quality due to system voltage profile disturbance is discussed. In this, voltage sag is taken as serious concern for hampered power quality. Voltage sag occurs due to fault in the system and transformer connections play an important role in this. For the analysis, software used is MATLAB/SIMULINK.
