This paper deals with the elimination of harmonics at PCC in the presence of non-linear type of loads. Introduction of five-level DSTATCOM at PCC injects compensating currents for the minimization of harmonic content in the source currents. Non-linear loads when connected to the system draw non-linear components of current leaving undesired harmonics at the source side. DSTATCOM when connected ...

This paper presents the three – level neutral point diode clamped inverter is used in a distribution static compensator (DSTATCOM), making use of the multi-level inverter advantages of low harmonics distortion and reduced switching losses. The pulse width modulation (PWM) inverter is employed as DSTATCOM compensating reactive power and eliminates the harmonics drawn from a non-linear load. A fu...
