Improvement of Power System Transient Stability Using Fuzzy Controlled Shunt Facts Device
B. Gopal Reddy [2] | Kamaldeep Sharma
Abstract: In this modern world, the electrical power consumption is vast and its power system is complex and faces many challenges due to growing demand and construction of new lines. Transient stability is one of the main system insecurity when large disturbances occur. Here at first conventional shunt facts devices Static VAR Compensator (SVC), Static Synchronous Compensator (STATCOM) are used as an additional supplementary controller to enhance transient stability. This paper proposes a Fuzzy Logic Controller to determine th signal to control STATCOM for damping the rotor angle oscillations of the machine to improve system stability. This controller is tested on 2-machine 3-bus system. Here the parameters like deviation of rotor angle, terminal voltages of buses are observed. The results are compared to conventional SVC and STATCOM to Fuzzy controlled STATCOM to prove that Fuzzy controlled STATCOM gives better results. The MATLAB/SIMULINK software is used to verify the model designed.
