DSTATCOM with LCL Filter to Improve Voltage Sags and Current Harmonics in Power Distribution System
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
An increasing demand for high quality, reliable electrical power and increasing number of distorting loads may leads to an increased awareness of power quality both by customers and utilities. The most common power quality problems today are voltage sags, harmonic distortion and low power factor. This paper presents the improvement of voltage sags, harmonic distortion and low power factor using Distribution Static Compensator (D-STATCOM) with LCL Passive Filter in power distribution network. The model is based on the Voltage Source Converter (VSC) principle. The D-STATCOM injects a current into the system to mitigate the voltage sags. a LCL( inductor-capacitor-inductor ) Passive Filter with pulse width modulation (PWM) was then added to D-STATCOM to improve current harmonic distortion. The simulations were performed using MATLAB SIMULINK version R2009b.
