A STUDY PAPER BASED ON SPACE VECTOR PULSE WIDTH MODULATION TECHNIQUE FOR POWER QUALITY IMPROVEMENT

This paper presents the comprehensive reviews for mitigation of the harmonic problems in the power supply which is caused by the non-linear characteristic based loads. The presence of harmonics leads to transformer heating, electromagnetic interference and solid state device mal-functioning. Hence keeping in view of the above concern, research has been carried out to mitigate harmonics. The most popular and best modulation method used among Pulse Width Modulation (PWM) technique is Space Vector Modulation (SVM) method as it generates low total harmonic distortion (THD). This paper also represents the current status of mitigation of power quality problems by FACTS controllers. The authors strongly believe that the literature survey will be very much useful to the researchers for finding out the relevant references in the field of power quality problems mitigated by FACTS controllers.
