This paper deals with simulation of STATCOM used for harmonic reduction with the aid of multilevel VSI circuit. The harmonics in STATCOM due to the voltage ripple are reduced. As a result, the size of inductor and DC capacitor can be reduced. The STATCOM has the great advantage of a fewer number of devices. The VSI is extremely fast in response to reactive power change. The simulation of the ST...
