Abstract

The paper presents a technique for improving the performance of a superconducting generator
(SCG). The technique is based on combining the effects of a fuzzy logic controller @LC) and a
thyristor controlled static reactive power compensator (TCSR). The fuzzy controller requires two
input signals and generates the output control signal. This signal is applied at the governor control
loop of the SCG in order to accomplish a satisfactory damping for the SCG low frequency
oscillations over a wide range of operating conditions. The TCSR is applied at the generator
terminal bus bar to change the transmission system configuration, based on a controlled firing
angle, for improving the system stability. The performance of the SCG equipped with fuzzy logic
controller (FLC) has been studied and the results were obtained in a comparative form with and
without using TCSR The results clearly reveal that inclusion of the TCSR is very significant to
improve the system performance and to increase the power transfer capabilities.
