Mitigation of Voltage Imbalance and Harmonics in Induction Motor Drives

S. Ramya, T. Manokaran, V. Rajasekaran

Abstract


Distribution system, as the name suggest, is the medium through which power is distributed among the end consumers Distribution systems are comparatively not as stiff as grid systems, so large starting currents and objectionable voltage drop during the starting of an induction motor could be critical for the entire system. Thus STATCOM is an effective solution for power systems facing such power quality problems. This report deals with one of the potential applications of static compensator (STATCOM) to industrial systems for mitigation of voltage dip problem. The dip in voltage is generally encountered during the starting of an induction motor. The model of STATCOM connected in shunt configuration to a three phase source feeding dynamic motor loads is developed using Simulink of MATLAB software. Simulated results demonstrate that STATCOM can be considered as a viable solution for solving such voltage dip problems. This thesis work aims at developing a STATCOM for induction machines with reduced voltage dip.
