Abstract: Power quality issues are of great concern in transmission and distribution system now a day due to the sensitive nature of the loads. The sensitive nature of the load increases with the advent of power electronic technology. It has become important, particularly, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply that results in a failure of end use equipment. In distribution systems voltage sag are more prominent. Power quality problems cannot be eliminated by using conventional filters. Therefore power electronic based Active Power Filters (APF) are most commonly used now a days. Voltage sag problems are the most frequently occurring and detrimental power quality problems. At present, a wide range of very flexible controllers, are emerging for custom power application to correcting the voltage sag in a distributed system. Among these controllers STATCOM are most effective devices, along with controlling methodology Mamdani Fuzzy Controller (MFC), ANN and ANFIS controllers. A STATCOM inject the voltage in series with the system voltage and a STATCOM injects a current into the system to correct the voltage sag. In their existing system they should be performance of STATCOM using PI controller showed to be better performance for solving voltage sag problem. But we are going to propose the ANN and ANFIS on STATCOM in order to increase the efficiency and their better performance to rectify the power quality problems.
