Abstract

Electric power systems needs pure sinusoidal output voltage and current without any interruptions at desired value. T-UPQC consists of combined shunt and two series converter based through filters for improving the quality of power in load side as well as source side. This paper deals with an implementation of a T-UPQC using two control techniques one is PI and other one is mamdani fuzzy controlling technique for mitigation of different distorted load conditions. They are maintained and manage the power into the T-UPQC. The model and the proposed control technique are discussed in d-q coordinates and the performance of this scheme is evaluated. Simulation results demonstrate satisfactory performance of the proposed new smart technique for the control of T-UPQC under varying loads using MATLAB-Simulink environment. The improvement of quality of power is analysed by comparing with two smart techniques use of the T-UPQC.
