【 摘 要 】

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