Performance Evaluation of Adjustable Speed Drives with DSTATCOM
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Adjustable speed drives (ASD) employing induction motors are widely used in the industrials and process control in the form of varied applications such as fans, compressors, Pumps etc. They are energy efficient and can result in substantial energy saving when properly installed. However, they inject high harmonic content into current drawn from the ac system. This paper deals with the application of a DSTATCOM for compensation of such loads. The MATLAB / Simulink based models are developed for adjustable speed drive loads. The analysis is carried out with and without DSTATCOM. The results shown in the paper proves that DSTATCOM can be used as a good harmonic filter. This paper presents the enhancement of harmonic distortion and low power factor using Distribution Static Compensator (D-STATCOM).The model is based on the Voltage Source Converter (VSC) principle. The D-STATCOM injects a current into the system to improve harmonic distortion and low power factor. The simulations were performed using MATLAB SIMULINK version R2012b.
