Abstract: This paper includes the performance of a Flexible Alternating Current Transmission Systems (FACTS) device, namely, STATic synchronous COMpensator (STATCOM) based on 6, 12, 24 and 48-pulse Voltage Source Converter (VSC), for the mitigation of voltage-dip caused by the starting of a high power induction motor. The different configuration of the STATCOM implemented improves the voltage profile feeding to a high power induction motor at starting by injecting a controllable current to the supply line having an acceptable limit of harmonics as per the standards of IEEE. The capability of the STATCOM to compensate the reactive power to the system when the voltage dip occurs due to starting of high power induction motor load is described.
