【 摘 要 】

The proposed paper presents power quality improvement at the utility interface for a Direct Torque Controlled (DTC) induction motor drive by making use of the design and implementation of a multilevel voltage source converter based on static synchronous compensator (STATCOM) employing an effective modulation control technique simulated in a MATLAB Simulink environment. The main objective of this paper is to present an approach capable of performing fast torque response and harmonics reduction in DTC drive. Hence, an efficient control strategy is applied, in order to reduce the voltage fluctuations like sag and swell conditions and also to reduce current and voltage harmonics in the DTC drive system. The work proposed in this paper is aimed at obtaining results exhibiting improved THD at the ac mains.
