ABSTRACT
A Power quality problemis an occurrence manifestedas a nonstandard voltage, current or frequency that results
ina failure or a mis-operation ofend user equipments. Utilitydistribution networks, sensitive industrial loads and critical
commercialoperations suffer fromvarious types of outages and service interruptionswhich can costsignificantfinancial
losses. Withthe restructuringof power systems and with shifting trend towards distributed and dispersed generation, the
issue ofpower quality is goingto takenewer dimensions. In developing countries like India, where the variationof power
frequency and manysuch other determinants of power quality are themselves a seriousquestion, it is very vital totake
positive steps inthis direction .Thepresent work is toidentify the prominent concernsin this area and hence the measures
that can enhance the quality ofthe power are recommended.
This work describes the techniques ofcorrectingthe supply voltagesag,swell andinterruption in a distributed
system. At present, a wide range of veryflexible controllers, which capitalize on newly available power electronics
components, are emerging for custompower applications. Among these, the distribution staticcompensator and the
dynamic voltage restorerare mosteffective devices, both of thembased on the VSC principle. A DVR injects a voltage in
series with the systemvoltage anda D-STATCOMinjectsacurrentintothe systemtocorrectthe voltage sag, swell and
interruption. Comprehensive results are presented to assessthe performance of each device as a potential custompower
solution.
