| Abstract | This paper presents an application of fuzzy control to determine the control signal of static Var compensator (SVC) for improvement of power system stability. SVC is a shunt type FACTS device which is used in power system primarily for the purpose of voltage and reactive power control. A fuzzy logic based supplementary controller for static Var compensator (SVC) is developed which is used for damping the rotor angle oscillations and to improve the transient stability of the power system. Generator speed and the electrical power are chosen as input signals for the fuzzy logic controller (FLC). The nonlinear fuzzy logic controller is used to overcome the problems generated by different uncertainties existing in power systems when designing electromechanical oscillation damping controllers. Generator speed and its derivative are used to design the controller. The control signal is calculated using fuzzy membership functions. The effectiveness and feasibility of the proposed control method is demonstrated by single machine infinite (SMIB) system and multi machine system. |
