Implementation of Fuzzy Logic in TCR-FC

Abstract

TCR-FC (Thyristor Controlled Rectifier with Fixed Capacitor) is a well known combination to improve voltage stability. Supplementary signals such as variation in reactive power, variation in frequency is used to enhance the dynamic response of the system. In this paper Fuzzy logic controller is used in place of conventional controllers. Deviation in Reactive power is used as a supplementary signal. Results with conventional controller & with Fuzzy Logic controller is shown in this paper. Results have been taken with the help of MATLAB simulation & programming.
