Opis

The power quality issue has remained a consistent point of concentrate, primarily in light of fact that it can get numerous economical consequences in industrial processes. Among the variables that influence quality of electrical power are those identified with transient nature. They usually begin with activation of capacitor banks, sudden change of loading conditions and many other unwanted situations occurring in distribution networks. In this Research we have carried out our analysis over phase angle jump occurring in system voltage due to different system disturbances stated above. Investigations of transients with and without capacitor bank and load changing scenarios are the main focus of this work. Numerical estimations of system variables for various transient voltages and inrush currents are calculated and their effect on utility and utility networks are examined. Finally their compensation perspectives have been proposed then. Eventually Spectral analysis of RMS value and Phase Shift of System voltage is made to extract the acceptable capacitor bank size,capacitor bank switching time and load variation by observing the transient over-voltages and harmonic components.
