Power Quality Improvement in DTC ofInduction Motor Drive Using VSC BasedSTATCOM

摘要: A The Power Quality (PQ) in distribution system is affected during its starting whn it draws large current. Voltage Sag one of the problem created by induction motor. When connected to a source, there dip voltage which could be critical for entire system. power electronics based fact devices called static synchronous compensator (STATCOM) used this paper improve quality motor with dtc scheme . result will analysed comparing THD source side and without statcom. Among all control methods drives, Direct Torque Control (DTC) seems particularly interesting being independent machine rotor parameters requiring no speed or position sensors.This aimed analyze DTC statcom improvement.
