Ann Based Unified Power Quality Conditioner for Power Quality Improvement

T. Veeranjaneyulu, K. Venkata narayana

Abstract


Generally, this paper proposes technique of FACTs based controller called as unified power quality conditioner, which is used to mitigate problems on transferring power based voltage and currents in the distribution systems. Reducing the rating of dc-link voltage without compromising the compensation technique is one of the advantages of unified power quality conditioner technique. The series and shunt controllers as series connection with the combination of capacitor and inductor for filtering process, and the system neutral is also considered and directly connected to neutral of distribution system for avoiding the utilization of fourth leg in the shunt converter voltage source inverter. This paper also presents a concept for improving power quality of a power distribution system such as an ANN logic controller along with the UPQC control strategy. The simulation results are compared for both conventional PI controller and ANN controller.
Key Words: UPQC Controller; ANN; Power Quality and THD
