| Abstract | ||||
| This paper presents the design and application of a combined fuzzy logic (FL) controller and a thyristor controlled static reactive power compensator (TCSR) to enhance the performance of a multi-machine power system. This is a 12-bus system which includes superconducting generator (SCG) and three conventional machines of different types and ratmgs. The FL controller is designed and implemented in the governor control loop of the SCG. While, conventional generators are equipped with different excitation systems and then conventional controllers. Also, the TCSR compensator is designed and included at different locations due to its increasing importance in suppressing power system oscillations ahd improving system damping. A fairly detailed Non-linear model of the whole system is built and computer simulations are used to demonstrate the effectiveness of the combined conml scheme in improving the static and dynamic performance of the power system under different disturbances and over a wide range of operating conditions. A com~arison is made between these results to select the most effective location of the TCSR. The mlt's are of great interest tp power system utilities, forming a gaint for future applications. | ||||
