Voltage Compensation Using D-Statcom under Unsymmetrical Faults in Distribution Systems with Static Power Converter Fed Dc Motor Load

In Industrial area one 11KV feeder feeds a static power converter fed DC motor load of variable power and some usual loads i.e domestic to industrial loads. Faults at DC motor load affect the other feeder loads. The L-G and L-L faults followed by open conductor fault on DC motor load effect the other feeder loads. This paper deals with the voltage dips and correction using the DSTATCOM, a custom power device, is proposed to protect loads from the effects of voltage disturbances on distribution feeder. Here the voltage dips and correction with D-STATCOM at the desired load point is studied by simulation.
