Abstract
Power system stability is one of the most crucial issues which deals with the response of the system to the errors such as: Sudden load change, Short circuit, Prime mover failure, Excitation failure etc. To maintain the stability and the damping oscillation of power system. Recently, FACTS controllers have been proposed to enhance the transient or dynamic stability of the power systems, e.g.: SVC, TCSC, STATCOM. In this a fuzzy logic controller is proposed to apply a suitable control signal to STATCOM. To improve the fault clearing time and transient stability improvement within a particular duration. It is found that the fault clearing times of 0.10sec for generator (G1) under test are self-stable with respect to simulation time. Proposed method is implemented in a single machine infinite bus system and the results are compared with conventional energy function-based controllers.
