Title

Fuzzy Logic Control Method for D-STATCOM to Mitigate Voltage Sags and Swells

Abstract

This paper presents a robust control scheme to vary the gate pulse pattern of the switching devices of D-STATCOM, a custom power device used to maintain the voltage profile of a distribution system dynamically. The work is carried out on IEEE 13 bus industrial distribution system with a shunt compensating device. The system receives 69KV from the grid and distribution feeder is rated for 13.8KV. D-STATCOM is realized using eight 6 pulse insulated Gate Bipolar Transistor (IGBT) voltage source inverters(VSI) for reactive power compensation and voltage stabilization for the cases of voltage sag and swell. The control strategy used in this work is fuzzy logic controller (FLC). FLC overcomes the drawbacks of conventional controllers like Proportional integral (PI) and proportional integral derivative (PID) controllers and provides a dynamic control action to vary the gate signals given to the power electronic switches which provides voltage support to the load bus thus mitigating power quality issues such as voltage sag or swell caused due to varying load patterns. FLC do not require precise mathematical modeling of the system as in the case of PI and PID controllers. A test distribution network, subjected to sensitive load variation is simulated with and without compensation. The response obtained clearly demonstrates the effectiveness and robustness in voltage stability and power quality issues. The simulation work is carried out in MATLAB/Simulink environment.
