Abstract

Power electronic components and Electronic converters gave birth to newlinenumerous new applications offering unmatched comfort flexibility and newlineefficiency to the customers Owing to the improvement in technologies large newlineamount of harmonics are introduced and they degrade the performance of the newlinethree phase four wire distribution system These effects of distortion also newlineaffect the point of common coupling where other loads are connected to the newlinesystem A lot of measures and mitigating techniques have been presented in newlinethe literature but each has its own drawbacks like circuit complexity lack of newlinereducing lower order harmonics occurrence of resonance problems with line newlineimpedance etc newlineTo overcome these defects the thesis proposes two techniques to newlineimprove the power quality of the system The first method aims at designing a newlineNeutral Current Compensator and the second method involves designing of newlineUnified Power Quality Conditioner The neutral conductor of three phase newlineFour wire distribution systems have been widely employed to deliver electric newlinepower to single phase or three phase loads The neutral conductor usually newlinecarries the zero sequence current due to the unbalanced loading among phase newlineconductors As more and more electronic equipment such as computers copy newlinemachines and adjustable speed drives are being used the harmonic currents newlinedrawn by their rectifier front ends also become significant newline newline%%%appendix p173-181, reference p182-191.
