Utilization of DVR with FLC to Inject Voltage in a Transmission Line
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
In this paper a Dynamic Voltage Restorer (DVR) is used for power quality improvement on transmission side for the voltage regulation, grid stabilization and efficient utilization. The DVR normally installed between the source voltage and critical or sensitive load. The vital role of DVR depends on the ef iciency of the control technique involved in switching circuit of the inverter. The DVR is controlled by using PI with fuzzy logic controller. The Fuzzy logic controller based on fuzzy logic provides a means of converting a linguistic control strategy based on expert knowledge into automatic control strategy. This paper presents a Digital validation conducted for different cases of fault conditions using the Mat lab/Simulink/Sim-Power software environment with the Dynamic Voltage Restorer scheme with fuzzy controller for ef ective voltage compensation, in rush current conditions and transmission line loss reduction.
