Static VAR Compensator (SVC) is a power quality apparatus from one of the member of Flexible AC Transmission System (FACTS) device family, which utilizes power electronics to manage the flow of reactive power in the system wherever it is connected. As a result, it is capable to offer fast acting reactive power reimbursement on electrical systems. In other words, static var compensators have their output accustomed to switch over inductive or capacitive current to facilitate control power system constraints such as the bus voltage. Additionally, static var compensators are installed at appropriate points in the electric power system to raise its transfer capability by increasing voltage stability, while under different system conditions keeping the voltage profile smoother. SVCs is be capable of diminish active power oscillations through voltage amplitude modulation. Furthermore, as an automated impedance matching device, they have the further benefit of bringing the system power factor close to unity. This project work deals with the development of a power quality improvement system especially for the voltage profile of the transmission line through Adaptive Nuero Fuzzy regulator based static var compensator. The basic idea for this project work came from the drawbacks of the PI based conventional voltage regulator that employs the voltage error (difference among the measured voltage Vm and the reference voltage Vref) to find out the SVC susceptance BSVC needed to keep the system voltage constant. The Adaptive Nuero Fuzzy regulator based static var compensator has the ability to handle the variation of voltage efficiently under the dual side three phase fault condition to maintain the voltage profile smooth and better for the system in comparison to the conventional PI based voltage SVC.
