REACTIVE POWER COMPENSATION WITH THE HELP OF VOLTAGE CONTROLLED D-STATCOM

Abstract

In this paper new method for voltage controlled mode of D-STATCOM will used for
reference voltage generation while in traditional method of VCM (voltage controlled mode)
reference voltage will taken as 1 p.u. In this new method it is possible to achieve unity power
factor at load terminal which is not possible in traditional method. Also, loss in the new
method will less as compare to traditional method. This is due to more current supplied by
compensator in traditional method as compared to new method. In both the method DSTATCOM each phase will contain three capacitor for removing high switching frequency.
Also, it is possible to clear sag for more time as compare to traditional method. Through
detailed simulation and experimental results, it will found that load will not affected due to
sag & also possible to achieve UPF in new method.
