Title: Voltage sag improvement of dynamic and static load distrbution network by using D-STATCOM
Abstract: The main target of this research is to allow the D-STATCOM using 6-pulse inverter to participate effectively in mitigating voltage sags. The basic idea of the voltage sag reduction using a D-STATCOM, which is connected in shunt with the system, is to dynamically inject a reactive power into the utility grid. In this study, 6-pulse inverter operation is conducted using the sinusoidal PWM. The voltage magnitude as well as phase angle are taken as a base to convert the DC link voltage (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dc</sub> ) on the capacitor to a voltage source using the developed D-STATCOM. This method offers structural simplicity and less calculation complexity by using Power System Computer Aided Design (PSCAD) software. Simulation results indicate that this method is effective and D-STATCOM has good performance and capable of mitigating voltage sag as well as improving power quality of a distribution system. Static and dynamic loads are used to deem the effectiveness of the developed D-STATCOM.
